Mustang Injectors in an M42 engine

--------------------------------------------------------------------------------

I remember seeing a post regarding replacing the stock M42 e30 from 1991 318i injectors with bigger ones from a Mustang.... Has any one done it here? Please let me know...and if you have the part number as well.... How easy is the install?

The stock injectors and the mustang injectors are physicly identicle. They both flow the same amount of fuel at 20.5lbs/hr although the mustange injectors are rated at 19lbs but this is at 33psi and not the 43psi of stock bmw, but the mustang injectors have 4 pintles or holes so the fuel is better atomized which produces a better burn and more power which is what we all want.

you can find the mustang injectors all day long on ebay just becareful of which one you buy the early mustang injectors are single pintle ask the seller to make sure that they are the right ones.

So was it confirmed that the M42 injectors are 20.5#/hr? The PN is still the same as the M30 injectors, and I am really sure those are 17#/hr. I put in the S50 ones at 17.5#/hr, and it is running just fine, even a little smoother than before. It would be running really lean if I went from 20.5 to 17.5.

I have used this site to determine the correct flow for the folowing injectors.
http://users.erols.com/srweiss/tableifc.htm

The ford injector is part number 0280150556 210.0 cc/min at 43.7psi (3 bar)
M42 injector is 0280150714 213.9 cc/min at 43.7psi (3 bar)
M50 injector is 0280150415 190.2 cc/min at 50.75psi

so the Mustang injector is just a little small but not enough to worry about.
The M50 injectors are rated at around 180 cc/min at 3 bar.

Oh, and what yeat Mustang can I find these injectors on? There is a Pick-N-Pull nearby with lots of them. I know only some have the 4-pintle injectors...was that year-specific?

haha i know, but yours is a crazy european car:) and i didn't have my Pn's to verify the same injectors. i was always told they were 17.5lb/hr. but thats ok cause i have the 4 pintle stang injectors.

Tim s some times we need to learn the hard way. I tied the M50 injectors because of false info on another bmw forum. After I installed them and recalibrated the SMT6 I am using on the MAF conversion I did notice a positive change so I though nothing of it and then I did some research on them and was shocked to find they were smaller. I then settled on finding injectors with the same flow rate as stock with 4 pintle since I did not think I needed extra fuel since the M42 runs rich any way. I installed the ford injectors recalibrated the injectors and was plesently surprised at the results. There was a significant increase in the torque curve and the car pulled much better at the top end.

I dont know what year mustang these came out of but there are plently of them on ebay as 19lbs injectors since the ford fuel pressure is less than 3 bar.

the m42 doesn't run rich...

03-31-2006, 03:21 PM
I have to disagree with you Kowalski, I use an A/F guage and it runs rich at WOT not by much but it is definatly not lean

tim_s
03-31-2006, 04:13 PM
sorry, no offence meant chaps! as for the running rich at WOT - barely any cars run stoich at WOT, most run 12s/13s AFRs, the m42 is pretty lean for performance really

do you have a wide band 02 sensor? or is it just the stock on?

04-01-2006, 02:07 AM
When I dyno'ed my car a while back the numbers were REALLY lean down low, and barely rich at higher RPM's. Here is a plot of the AFR. This was with stock injectors as well.

When I dyno'd my car stock the A/F was in the low 13's across the board. The dyno operator said that is about what they aim for when tuning for power.

tim_s
04-01-2006, 05:27 AM
bmwman, i'm not sure yours was running right on that dyno run, that at WOT? that seems way too lean at 3k and too lean throughout, even for a standard m42. all your motronic sensors etc on form, o2 ok and fault codes clear etc?

bmwman91
04-01-2006, 01:37 PM
That was on the previous car. I am pretty sure everything was running A-OK. I heard somewhere that the Conforti chip is tuned a little lean, but I could be wrong. Anyone else have a plot to compare it to? Stu McHenery, YEARS ago, said that the M42's problem is its injectors not flowing enough, and it does lean out a little up top...it was something BMW did for emissions.

i'm not sure if it leans out at high rpms, but 20lbs injectors sound ok to me for a car with 140bhp. i know the standard chip is configured towards stoich for economy, but still imo that AFR graph you've got really seems way too lean at 3k, a bit up and down and generally a bit lean really. 16.5 at WOT at 3k is nasty. 15 or so would be ok, but 16.5 is surprising. you'd expect it to at or below stoich all the way on WOT, mb a bit higher at low rpms. even if on the graph yours wasnt at WOT until about 3.5k, 16.5 is lean anyway.
what power did it put down like that?

tim_s
04-01-2006, 02:35 PM
i wonder if all m42s are like that, would be good to have a comparison...

04-01-2006, 08:02 PM
just go to the 19lb ford 4 pintle ones, since they're the same flow, but better atomization.

I don't know about all this Ford injector stuff. If you guys want to get real technical you can get the RC custom or software programable ones, but they are real pricey.

Only Ford part going on my car is the Ox sensor. I think I used a Mustang or a Probe one on my last car as it was the cheapest Bosch on I could find. I think it was exactly $21. It's exactly the same one as the one for the BMW, minus the harness plug. Splice three wires and you're back in business.

I believe it's under the intake manifold. How long does it take to remove the IM for those that have done it? It looks pretty straightforward though.

kowalski
04-13-2006, 10:11 PM
its easy, all you gotta do is take off the throttle boddie, disconect the thottle cable and the vacume hoses and the FPR hose, then pull off the heated spacer, and then take the manifold off and your there. the only part thats a pain in the ass is putting the FPR hose back on... while your doing this i recomend replacing most if not all the rubber hoses.

jfdublyu
04-14-2006, 06:24 PM
i bought all the vaccuum hoses from bavauto a while ago but haven't got around to replacing them yet. this will give me the motivation. The throttle body looks like a pain to get off though, is it not? it looks like 4 bolts (maybe 11mm or so), 1 on each corner, and it looks impossible to reach the bottom two w/ a wrench or socket. any tips?

It is a bit of a pain reconnecting the coolant lines below the TB, actually it is a real PITA. Other than that it is not too bad. Just be careful yanking the injectors out. They can be a real pain to remove.

Why do you have to remove any coolant lines? I mean, might be a good time to replace these, but I don't see why you have to remove coolant lines to get at the intake manifold.

The part that makes me nervous is that my throttle cable is all taped up with electrical tape up by the pivot point. I'm nervous to see what's broken up there. :eek:

bmwman91
04-16-2006, 01:10 PM
I am referring to the little coolant feed hoses that feed the TB's de-icer. They are really short, and connect to the TB underneath it, but it has to already be in place for them to reach their fittings.

The easiest way I found to het this done was to unbolt the TB, unclamp the hoses, and remove the TB first. The manifold is cake after that. Installation is the reverse.

Check the FPR vacuum line for cracks. I got a new hose (rubber, braided on the outside with a nylon sheath) for like $.68/foot at Kragen. It is not a good thing to have a leaky one.

Also, check to see if the lower manifold is all gunked up with clack goop inside. If it is bad enough that you can see the goop in the injector bungs, consider removing the manifold & cleaning it. All you have to do is loosen some more bolts (MAYBE replace the gasket, if it rips, or you do not have any high temp silicone RTV), pull the vacuum line out of the brake booster, and disconnect the 2 little segments of fuel line going to the rail. Just be careful doing this as gas will likely come draining out. You may as well replace these fuel lines too, a 1' segment will more than cover the job for these 2 little bits.

Removed the upper manifold on my car yesterday to access a water line that was leaking. I thought it was straightforward, mind you this was the first time I've ever taken it apart.

In reference to the FPR vacuum lines that have been discussed, what do those look like and where are they located as I've removed a few hoses and want to ensure these get replaced.

kowalski
04-16-2006, 10:20 PM
the FPR line is located on the throttle body, it attatches to the small valve on the side of it.

how come you removed the coolant lines on the by the TB, you can just shimmy that thing off without removing the lines if you want... thats what i do.

I would like to upgrade my injectors as well and ran across 19# injectors on ebay.

The info below is copied from the ebay page I found.

Ford Bosch Design III 19 lb 19lb/hr MPI (multi-port injectors) injectors, p/n's F4SE-A1B, 0280155700. 204cc @ 3 bar. Quantity 8. These injectors have a disc-type four-hole fuel delivery system in comparison to the single pintle of the Design II's for a more efficient fuel-atomization. This results in a more efficient power delivery and better mileage.
Also a great upgrade for BMW's; fits the BMW M20 fuel rail. These were pulled from a running engine and have been electrically tested. You get the exact ones in the picture.

I just converted my volvo 960 from the original pintle injectors(0-280-150-762) to a set of 4 hole injectors from a 96 Saab 900 V6 (0-280-155-712). Both the old and new injectors are around 20# so I didn't go up or down in size but the difference from behind the wheel was very noticeable. More torque at every rpm, smoother idle and easier to start.
Now I've turned my attention to the bmw. Searching through yards this weekend I found 2 sets of Ford injectors for cheap ;)
0-280-155-700 (F4SE-A1B) from a 96 V8 Thunderbird.
0-280-155-715 (F5DE-B5A) from a 97 V6 Taurus.
Which ones should I install?. I'm leaning toward the Thunderbird injectors. Different sources quote different specs for these injectors. A couple of people responding to this thread last year said they were using both of these types. How is it working out? Any feedback?
For anyone that hasn't seen the difference between single pintle vs 4 hole injectors:

Bosch old style EV1 injectors have 150 in the PN. EV6 injectors have 155 in the PN.
http://farm3.static.flickr.com/2379/2055128589_31ab4630d6_o.jpg

Bosch first introduced these injectors to the market in 1996 and then slowly phased out the pintle injector over the next 5 years.

Sweet! Do you remember the part number of the injectors you are using? Did fuel economy or power change?

I swapped in the the ford injectors (0280155700) on Monday. My god this fuel rail is such a pain in the ass. Anyway, the EV6 injectors are not a direct swap into our cars. Funny how everyone failed to mention this. I needed to put a 1/2" washer around the bottom of the injector to keep it in contact with the fuel rail. The little clips are not strong enough to keep the injector planted in the fuel rail when the system is under pressure. The injectors need to be squeezed between the intake and the fuel rail. I reinstalled the upper intake without a gasket because I didn't have one on hand. instead i used a some RTV to get a good seal between the two intakes.
As soon as I started up the engine, the first thing I noticed is damn smooth idle. This swap is worthwhile just for that. These injectors seem to react much more quickly compared to the factory EV1 injectors. I thought I had a worn out ICV because every time I turned on the headlights or switch on the AC, idle would almost die, and come back. Sometimes I would get some idle oscillations too. Now its perfectly even during load changes. Throttle response has improved noticeably and the engine is smoother as you go up through the revs. So far I put about 160 miles on these injectors, mostly short trips. The fuel gauge is about half way between 1/2 and 3/4 marks. We'll see how fuel economy does in the long term.
After more research I realize that in the saab injectors I put in the volvo were 21# vs the original 19# injectors. The 6cyl volvo engine has an AMM and knock sensor (Motronic 1.8) so it can adapt to the larger injectors. I'm not sure if the M42 has the same ability, but if I find another set of 21# saab injectors, I'll try those out on the M42 along with some intake work. When I find my camera I'll take some pics.

EDIT: The washers are not necessary. These injectors fit without any modifications. I'm taking down the pics of the washers because it just seems to confuse people.

Excellent! Its definitely not the E36 325i injector but it seems like the perfect size for this car. Did you run into the same problem with mounting the injector? If you get a chance to read the part number off of it would be helpful. I'm compiling a list of compatible injectors for a future write up. If its a bosch injector, I'm interested in the last 3 digits. 0280 155 XXX

Thanks for posting the Bosch part numbers. After 2 weeks of driving, I filled up this morning. 385 miles on 12.4 gallons. You do the math. This included about 20 cold starts, some highway, some city, a little stop and go traffic and a couple of canyon romps. The car also manual steering, electric fan and 3.64 gears. Its a hell of a lot more fun to drive than when I got my hands on it 8 months ago.

The picture is a bit blurry but you can see the 1/2" washer at the bottom of the injector. Oh and 190 miles at 1/2 tank so far.

Justin,

Just curious... is it really "safe" to run the vehicle w/ your "washer mod" on the injectors? I would be concerned about a fuel leak if the injector were to shift or not be 100% sealed properly due to having to use a metal washer.

That solid orange, skinny Mustang injector is the newer style "mod-motor" injector as used on the 96+ SOHC & DOHC Mustangs (and other Fords).
http://www.witchhunter.com/flowdatapix/b0280155700.jpg


The other Mustang injector, which has the silver body & yellow top is the 5.0 19lb injector that was used on nearly all 1986-1995 Mustang 5.0's (and other 5.0 Ford products, including the Crown Vics, Lincolns, Broncos, F-Series trucks, etc).



You cannot safely use the newer style solid yellow injector in place of the older style injector due to the differences in height and sealing characteristics of the O-rings & fuel rail assemblies - mainly because of possible fuel leaks. Granted we are talking using these parts in BMW's so some of the above is null & void as it applies to Fords, but if it were me, I would surely use the same type of injector as a replacement (exterior characteristics/dimensions - height/o-rings, etc) rather than trying to make a different type "fit". Again, I'm not saying what you did is 100% incorrect, as it does seem to work, however, IMO it's not the best solution and just does not seem as safe w/ using a washer to hold the injector into the fuel rail & intake.

Everyone is entitled to their own opinion and im certainly not trying to push this modification as the end all be all in fuel injectors. I disagree on a couple of points. The ford injector is exactly the same height as the bmw injector, using the same size injector seals and the same electric connector at the same height. The only critical differrence is the shape of the body. Most manufacturers use the pintle cap as a mouting point of the bottom of the injector. BMW used the metal body, hence the need for a 1/2" washers. Both injectors were manufactured by Bosch. Yes, the washer is my own bodged invention in place of the weird bmw pintle cap but in 6 months and 6k miles it has never leaked. I've checked them frequently under pressure with the engine both hot and cold.

The FIVEOMOTORSPOR.COM site shows the 19# mustang injectors as Bosch #0-280-155-710 and #0-280-155-700. The picture for the #700 injector does not look like the stock injector (0-280-150-714 for the M42/M30) though. While i haven't found a definitive picture of the #710 Mustang injector, from the bellow link it looks closer to stock than the #700. It is also not clear from the below link if the #710 is four hole or one hole? I say closer to stock because of the clip that slides into the groove of the injector and around the fuel rail port to assist with holding it in place.

It appears the benefit of the #700 injector may be that is has four holes (vice a one-hole pintle for stock or a one-hole disc-type for the #710) but you may need a washer at the manifold end in order to help hold the injector in place because the clip can't be used?

Sad, but true. Volvo fan, plug wires, now injectors. Pretty soon I'll have to swap badges.

The stock injectors (0280150714) are 20#. I initially replaced them with 19# ford injectors and life was good. Then I fixed the hot air intake, picked up a bunch of throttle response and acceleration in the mid range but nothing at the top end. Its obviously getting enough air now so, maybe the solution is more fuel. So goes the theory anyway. The dyno will tell all.

So the knife edging will help huh?
Seems like an easy little project to pass some time.

I like the way the high beam intake looks. It does blend in better with both sides.

I'm considering eliminating the high beams and getting some dual filament H4 if I can find good rewire info. I think two black intake areas would look nice and I could pipe some outside air into the intake and down the header side to help scavenge hot air from the engine bay.

I'll be hitting up the junkyard soon and looking for volvos to get wires, fan and now injectors too.

Cheap made in india but the reflectors are just as good as my old hellas. Don't use/buy any of the Autopal bulbs though. Even the 100w version are total garbage and most have the base on crooked. Pick up H4/9003 bulbs at the store. Napa carries German made 80/100w bulbs.
If you have sealed beams the H4 headlight is a direct drop in. No rewiring required. Elipsoids are a different story.

The fan is volvo 940/960. 850 also works but the shroud is a harder to use.
Plug wires are volvo 850
Injectors are 95-98 volvo 960/S90/V90. In general yellow injectors are 18-20#, Dark blue is 20-22#.

I'm hoping one of you can help here... I can't find any of the bosch 710 injectors, but can find plenty of the 700's all over. Well, I want to get more fuel in than those provide... would like a 22.5 lb injector. My last dyno run showed I was lean throughout the run. I am running a set of Delta regrinds (shrick specs) that came with my new motor. Also might switch to a conical filter instead of the stock box.

Will either, or both, of these sets work? Thanks a bunch for your help guys...

I just felt like adding, it is best to use Bosch 150 style injectors if you want a direct fitment and no washers.

All Bosch injector part numbers start with a "0 280 XXX XXX". The first three X's are the injector style. Bosch has two commonly used styles, the 150 injector which is wider, and the slightly newer 155 style which is narrower. So a 150 style injector will have a part number like "0 280 150 947".

When it comes to the two injector styles, practically no dimensions are the same, other than the same O-rings. In some cars the 155 style don't work at all. I recently helped out with an efi conversion on a 1989 Mercedes 190E, and where the 150's were able be used, the 155's were a lot shorter and wouldn't have worked well.

As an additional note, most car manufacturers run slightly undersized injectors since smaller injectors provide more accurate fuel metering and better fuel economy. BUT in the case of the M42, these are perfectly sized(20.35lbs/hr) for the engine and should be able to support 138 hp with 43.5 psi/3 bar fuel pressure (BMW regulators run at 3 bar + or - 0.06). So if anyone is claiming their car is running either lean or rich, then likely they have a mechanical problem or less likely BMW didn't make a very good fuel table.

There are 2 versions of the 155 injectors. Standard body and long body. The long body shares all exterior dimensions with the 150. There are a few versions of the 150 body injector with a 4 hole sprayer but mostly in the 17# range which is useless to us.

Short vs long version.

Personally, I'm gonna experiment with the Bosch 0 280 150 947 injectors if I ever do my megasquirt install. 24.5 lbs/hr, 150 style so they fit without washers, pretty widely available, and with an adjustable fuel pressure regulator they can be used for a very wide range of power. Supposedly they use a disc instead of the normal pintle as well.

Sounds like a solid plan. I know theres a bunch of 4 hole injectors out there with the 150 body style that I don't have the specific info on. Definitely add new info you find here. This thread will become a valuable resource.

So far I have about 500 miles on my 0280155702 22# Volvo injectors Fuel economy and power have been stellar. I averaged 31 mpg on my last tank over the span of 3 weeks doing short trips. With gas being where it is, I find myself riding my bike a lot more and driving a lot less.

Those mustang injectors that always seem to come in batches of 6, are actually off a 96-98 Ford taurus 3.0 24 valve V6. Some sites quote them as 22.x# while others have them closer to 24#. The truth lies somewhere in between.

I wasn't trying to say that bigger injectors improved fuel economy. My mileage didn't change at all when i switched from 20# 155 injectors to 22# 155 injectors. Keep in mind that I've done a lot of other things to make the car to make it more fuel efficient like manual steering, efan, 3.64 diff, ditch some weight etc. Most of my driving is around Marin on the 101 at non peak hours. It would be a lot worse in Berkeley traffic.

I got these for free and will work great for now, but I will switch to 22.5# 150's in the future.

I'll check the PNs, but the Subaru WRX has the same body as the long ones. They are light blue in color, and are 420cc.. you can cut the pintle cap off and have 800s..
Of course, these would require some serious fuel management, and worthless unless F/I..

The injectors I used were from an '04 Mustang GT with Bosch # 1 280 150 556. These are a direct fit and depending on which list you look at, may be either a slight upgrade in flow or the exact same as stock. You may also want to look for 1 280 150 943 (I have 4 of these as spares if anyone is interested). These are either the same flow as stock or slightly less and quite a bit more plentiful. Again due to which injector list you believe. Both of these do NOT need washers to fit correctly.

Are you using "used" injectors or rebuilt, or "sonic cleaned" or what for your car, tjts1?

Kingsly
11-16-2008, 04:19 AM
I, personally, am using 'used' injectors. I cleaned them pretty throughly, and ran the car on a bottle of injector cleaner mixed with about a gallon of fuel to make sure. Oddly my old injectors also seemed to be of the 4 hole type, but with a different head design. Either way, my car pulls much harder and revs more readily, plus has a smoother idle.

(also, I fogged my airbox, which on an E36 was as simple as pulling off the funnel/muffler thing and throwing it in the trash. One of these days I'll have to go to home depot and get some longer tubing so she'll be sucking something other than engine bay air)

I am running used injectors that have been sonic cleaned. I bought them here from dbgurbbs and sent them to witchhunter.com for cleaning. It's expensive but they do flow tests before and after, send them through 3 cleaning cycles, and replace all the o-rings, filter baskets and caps. They looked awesome when I got them back.

Are you using "used" injectors or rebuilt, or "sonic cleaned" or what for your car, tjts1?
I have 0280-155-702 injectors in my car right now. There is no such thing as "rebuilt" injectors no matter what some vendors might have you believe. I clean them myself using this procedure.
http://fordfuelinjection.com/?p=82
If anybody is interested, I still have a large stash of 0280-155-700 and 746 19#injectors. I can sell for $15/injector + shipping. I also have 21, 22, and 24#. Let me know exactly what you need.

The little plastic caps on the ends of my injectors were pretty brittle, I took them off. Do I worry?

I think that it should not affect the spray pattern. I wouldn't do it, but I get paranoid about those kinds of things. Just make sure the bottom of the injector is getting a nice tight seal with the manifold, you don't want any leaks.

You may be able to find an online parts store that can sell you just the caps, or maybe check with the injector manufacturer (bosch?).

I'm getting a pretty tight seal with just the o-ring, making sure to coat it with motor oil beforehand. The little plastic rings that go on the end don't seem to provide any structural benefit. They don't compress the o-ring or anything. One fell into the engine while test fitting. Naturally I didn't want that and took the others off.

I also did the 1/2" washer trick, and can't see how it provides any help whatsoever. Then again I had just single handedly torn down my entire top end. A bit too exhausted at that point to really investigate...

Any type of injectors you could use is the M3 pink top injectors. They are rated at 210CC which isn't far from the stock ones. The M3 injectors has 4 holes as well.
Guys could we make a list with parts numbers and flow rates and a little description stating with what mods should work best?
Also its extremely difficult over here to get those mustang injectors over here, any thoughts on those m3 injectors. 2.3 or 2.5 m3? flow rates of the m3 types?

Awesome thread guys, actually many awesome threads on this forum!
I bought my 318is only a couple weeks ago and i only dealt with M20s in the past so please be understanding :-)
I am installing a turbo on the M42 but I only plan on boosting 6-7psi on it, to give it a little boost on a well built, low budget set up.
I understand the stock injectors are around 20# on the M42, and I'm thinking of installing some 22-23# injectors to help the fuel supply under boost, maybe 24# tops. keeping in mind that I am in france and don't have fords all over the yards, what cars could I look for to find those injectors that will fit? Volvo? maybe other BMW or Mercedes?

thanks a lot!!

Welcome to the forum. The stock injectors are either 19# or 20# depending on who you ask. I'm using 22# injectors in my naturally aspirated car without a problem so under boost I think you should be using at the very least 24# injectors. I don't know which cars in europe will have these but if you want a set of 24# injectors I can ship to europe.

How much do you ask for 24# injectors? do they have the 4 pindles?
I found some 0 280 150 157 off of a jaguar 6 cyl 4.0, they are rated 22.3# @ 3 bar but they are low impedance, would that be a problem?

The injectors would be $50 + shipping. I will throw in a spare just in case because these are used. When I get home tonight I'll have the part number. You need to use high impedence injectors on the m42. I would be happy to sell you the 24# injectors but I have to be honest, I don't think it's going to be enough even for 6-7 psi. I think you need something in the region of 30# for your aplication.

Well as near as I could tell the injectors off my '93 had four holes in the pintle, but they were buried way back into the injector assembly and hidden behind plastic bits. The mustang ones are right up front so they literally spray directly into the intake mani. :)

Some of the later E36 M42 injectors used a sort of air injection into the fuel injectors in an effort to reduce emissions:
http://www.motortraders.net.au/groups/group.asp?group=1&menu=88

I'm not sure you'd want to swap this style over to the Mustang injectors because: you already have 4-pintle injectors, and emissions might be worse (if that's a concern) w/out the air injection.

True the E36 M42 injectors had a larger bottom end diameter. Putting "standard" injectors like from a Mustang into the manifold requires special spacers.

You can take a standard injector, stuff it into the plastic housing from the old injector and plug up the vaccum port at the top of the pic. The injector and plastic housing separate.

The E36 M42 injectors are the same size, I've got some sets of them and they are the same, the M44 have the larger base we are talking about here.

I'm not sure it's air injection, I'm stripping an M44 at the moment and the additional air inlets are for the idle air control that is mounted to the side of the throttle body.

Visited my favorite pick-a-part yards and found some of the yellow 0 280 155 700's from mid-90s 4.6L V8 Fords at $5 per injector. One was from a Mercury Sable, the other a T-Bird LX. There was a large list earlier on this thread about the possible applications, but the biggest help was getting answers on where these injectors were installed as standard equipment. An 8mm socket wrench was useful for undoing the Ford fuel rail bolts.

Haven't installed them yet, as I am in the mind to replace a slow-leaking radiator first (the RTV fix on the coolant reservoir tank could not be extended to other plastic parts).:(

Just had a quick search, came up with this site that tells me the 'Bosch Number', 'cc/min @3bar' and 'Resistance (ohm)'. Not 100% sure I get it all, the volvo ones posted by tjts1 give a cc/min of '231' and a resistance of '12.0'. The first two I posted give a cc/min of 200 and resistance of 15.9, which is ovbiously worse. The last set I posted show a cc/min of 311 and resistance of 2.4 though! VERY low resistance (bad?) but high flow rate! Bearing in mind the Ford ones tjts1 posted give readings of 200 and 14.5.

Thanks!

See the link I posted at the end of my post - pretty much the same data.

Essentially, the last injectors will flow LOTS, BUUUUT the resistance is very low. I haven't the foggiest idea how well they'll fit, if they actually do, and I have no clues about the resistance. My guess is that I want similar resistance to your volvo ones, which is 12. What effect is this going to have? Etc...
(engines are one of those things I don't do much, although I'm getting there! I know how to do the HG now, and strip it down!).

So, flow sounds great, but that resistance leaves me clueless. If it was similar/close, they'd probably be worth trying for Ģ10! As is, an educated person's idea will be very helpful.

Thanks!

tjts1
04-21-2009, 05:41 PM
There are generally 2 families of injectors. High and low resistance Our injecotrs are high resistance and should only be replaced with another high resistance injector. Anything over 12 ohm is considered high.
For flow rate, I wouldn't go more than 20% over stock for a NA aplication. I hope this helps

My friend in the uk pointed out that GM 2.5 v6 used in the late 90s saab 900 and vectra (probably a few others) has 22# 4 hole injectors.

Thanks for that - thats also added in another option! Tomorrow I'll find a pic of a stock M42 injector, start comparing shapes so I can get one that looks the right type, ask sellers for photo's of the injector tips etc!


Ok, so high and low impedance is cleared up, how about the differences within them? Stick with high since thats relevant...

What'll the difference be on an injector rated at 200 cc/min with say a 12 resistance rating, and one at 200 cc/min, but resistance of 15.9? Faster flow on the 12. Which essentially makes naff all difference?

Important thing to remember: :D (so, aim similar/slightly higher)
M42 injector is 0280150714 192cc/min 15.8/9 resistance. (please double check that for me!)
(there's so much variation, the site you gave me said the above figure, the site I provided says 200cc/min, and someone at the beginning of the thread says 213cc/min! ARGH!)

Aim is for about 200-205cc/min about 16 resistance, pretty much like you then!

You've been a star, BUT I think you desperately need to lower your car ;) Or at least stiffen her up :D



Update: I'm still searching around atm, I suspect I'm going to quite literally go through the list of specs and compare whats viable! I'm researching the ones from V6's atm, dropped a few emails, had one reply stating 'These are a split spray pattern 'V' type.' which I'm trying to verify with photo's. If I get some, and find 4 pintle ones, I'll post up the results.

You'll all be happy to hear you CAN get 4 pintle Vectra 2.5 V6 injectors, and they DO fit! I think they're from the GSI version - the non GSI ones are the ones with a v shaped hole.

But, like tjts1 I had to do some modding - I didn't have washers big enough and I live in a village with no shops, so I got a file out and started filing the fuel rail mounts down. took around 1.5mm off, and they now all sit fine and dandy! No pics of that though I'm afraid - you can imagine what 2 mounts look like filed down!

When fitting, I fitted them to the fuel rail, THEN inserted them in the holes. Not what the picture shows, that was when I first put them in, and realised that that wouldn't work!

Car feels slightly smoother and torquier. Its also stopped popping at all on downshifts :( I have 'knife' edged the throttle body butterflies and made a decent intake (piece of pipe through what was the main beam to airbox). Plan for tomorrow is to remove the second midbox again, I know that'll help too!

I'm not sure what engine work I can actually do to make the upgrade worth it. Although the car does seem to be doing as well, if not better on fuel already (the car is running some chip that it came with), but I'll keep checking that as the miles go by.
What other mods have you done? Much difference? I'd love to cam the car, but I'd have to find one 2nd hand (I don't do expensive!)

bbarnumboy - I'd say no. Unless you're doing engine mods, and so need to upgrade for higher flowing injectors of course.

I'll report back about the fuel economy, but despite the ones I got (part #0280155712) apparently flowing 213cc/min, I think the fuel economy has improved. Sitting at 70-75mph on the motorway she was sitting at the mark after 30mpg mark (is that 40 or 50 mpg?), whereas I used to get 35ish mpg on the flat. Also, after thrashing the car around a bit both sat and sunday I'm still going to get about 300 miles to a full tank, whereas I used to JUST get 300 miles if I took it easy all the time.
This still needs lots of watching though, and I'll report back.


Pitch-Black - as above, and I think it depends on what accompanying mods you do. When I cut my midbox out again (leaving only the frontbox and cherry bomb rear) I noticed another power increase! Without doing this, there's a minor increase all-round, but with a better flowing exhaust too, its definitely better and worth it for the Ģ30 I payed for the injectors, and Ģ17 I payed for 2meters of stainless exhaust tubing MONTHS ago, and the Ģ50 I payed for the 2nd hand welder, thats done pretty much all my welding on the car!

Nope, I didn't take the thread out, I was just very careful not to mangle the thread so much it wasn't at all useable! Obviously, if you can be bothered, removing it WOULD be the best idea. It'd also make filing it down a hell of a lot easier!
Just to make life easier - were stock injectors to go back in, they would still fit fine, they'd just sit slightly further in.


tjts1 - when I did mine the o-rings were pretty much sat on top of the injector holes, hence filing it down. So obviously it does apply for some injectors, although filing down is probably better than fitting a washer in there ;)

Hey guys, I just made the injectors swap on my E36 '93 M42. I upgraded to the 0280 155 712 Vectra B 2.5V6. 20euro all 6 pieces, great deal. The original injector as you know flows 200cc, and this one flows 213cc. Both of them are 4 pintle caps, but the difference is that on the vectra ones the pintles are right "on top", while on the original the pintles are 2,5-3cm inside. So, besides the 13cc difference the spray pattern is definetly an improvement.

For these injectors, filing would not be a good idea at all. If I push the injector all the way in, until it reaches the plastic edge, the Oring is already inside the intake and does no seal anymore. My english is rubbish and I'm not sure I explained it correctly. To put it in another way, the distance between the oring and the plastic edge of the injector is larger than the thickness of the intake. So if you file the mounts enough for the intake to support the injector properly, the oring would "fell" in the intake valves chamber.

With the injector secured on the rail with that clip, there is the 2,5-2,8mm between the plastic edge and the intake. The washer is not necessary because the injector sits nice and fine on the fuel rail and is also secured, but because I'm paranoid, I added the 2,5mm washer to eliminate the possibility for the injector to go too deep, just in that one in a million cases the clip fails.

The result is quite good, much more low end torque, different sound of the engine, more relaxed overall. Would recommend the upgrade.

papercutout
06-22-2009, 05:54 PM
I actually had a gap between the injector and the intake hole - hence filing it down so they sat inside. A gap would mean unfiltered air etc getting in. Guess it depends on the car/set-up.

Glad it worked though!

Ok, back with some updates on the situation. I was out of town for a week with work so I couldn't test the car in all aspects. Last night I had a few runs with two of my friends, both E36 320i. One of them has the engine running perfectly with 15'' alloy with 195/60. The other one has problems with vanos, the engine does not run very well and has got 17'' wheels with 245 tyres. We usualy run from 50km/h to 180km/h.

Before the swap, I only ran with the second one, that is not working very well and has got big wheels. It used to go 3 car lenghts ahead. Last night we were perfectly equal two times till 160km/h, and one time my nose went ahead went ahead 2-3m at 180km/h.

With the first 320 that was properly running he went ahead 2 car leghts, I do not know if the car has resoft or any chip. Probably not. I wonder what the difference would have been before the swap. Shameful I guess :)

I still dream to the day when an M42 will beat a perfectly working straight six, of course without supercharging it.

Any trick to separate the fuel rail from the injectors? I have the Fuel rail and lower intake manifold off the head and just thought I'd ask before pull the injectors and rail off. I should have a set of eight 155 700s coming this week (only need four) and taking the time to replace hoses and clean things up before they get installed.

I did pull the retention clips for the injectors, but don't know if there is anything else holding the base of the injectors in other than the friction of the o-rings.

As long as you have removed the small square clips holding the injector to the fuel rail, it's just a matter of pulling and twisting harder. Hold the fuel rail with one hand as close as possible to where the injector is attached.

As long as you have removed the small square clips holding the injector to the fuel rail, it's just a matter of pulling and twisting harder. Hold the fuel rail with one hand as close as possible to where the injector is attached.
good luck
Justin

Actually got the injectors off fairly easy. I had the lower intake off the head already so I didn't have so much leverage to pull them apart.

So, I shot both sides of the injectors with PB Blaster, let them set for 30 minutes, then used a pair of brake caliper compressors between the rail and the lower intake manifold to carefully push the rail off the first two injectors. Then used one of the brake caliper compressors to remove the third injector, then just twisted the fuel rail to remove the last one.

The original o-rings were very hard and using this method made it very easy to remove them without damaging the rail or my shoulder.

Putting many things back together today, I expect to have it all back together next weekend.

With the injector secured on the rail with that clip, there is the 2,5-2,8mm between the plastic edge and the intake. The washer is not necessary because the injector sits nice and fine on the fuel rail and is also secured, but because I'm paranoid, I added the 2,5mm washer to eliminate the possibility for the injector to go too deep, just in that one in a million cases the clip fails.

The result is quite good, much more low end torque, different sound of the engine, more relaxed overall. Would recommend the upgrade.

I recently also installed these same injectors (cheap ebarf deal). I ended up losing the washers altogether since I expected annoying rattles and I just trust the circlips not to fail. So far they haven't. The increase in power and even more so in smoothness is remarkable. Best upgrade for the small budget imho.

Little higher flow rate then the mustang injectors.

They should work fine. I used those on my megasquirted mercedes. I have 22# injectors in my car and it runs great. With a chip it leaves a little bit of black soot on the rear valance. No visible smoke though. It didn't affect fuel economy.

Eric Happy Meal

Any Bosch 150 injectors should fit IIRC (in the middle of the part #, xxxx 150 xxx). The 155 injectors are too short, but can be persuaded to fit.

The yellow 19# Bosch injectors are installed in many Ford V8s, from Crown Vics to Econolines to Mustang GTs. Don't go after the older CFI single-point setups. Look for the 'cash for clunkers' cars...I've had the best luck there. They have the right impedance too.

I'll bet turbo cars would be a good place for uprated injectors, but I'd worry that exposure to heat soak might wear them out.

I'll bet any '90 V8 would have what you need. Later Fords have a different injector plug and won't work. Look for colored plastic-bodied skinny injectors. They'll be the ones. I think anything after 1990 is OK.

Ford uses small bolts to hold down the rail. I'd think an I4 like a Focus is easier to get at...but I'm not sure if they use high-flow injectors.

I found a nice set on a VR6 VW, but I'm unsure of their flow rating or impedance. They're a bluish color.

I was surprised at how small the injector holes were when I bought a set...more like motorcycle injectors...

Ford taurus 24v up to 96-97. After 97 ford went to a round injector plug. AFIK these are 24# injectors. Sort of the high end of the usable range of injectors for a naturally aspirated M42. Anything between 19#-24# will work depending on any other modifications you've done to the engine or your target AFR.

The newer style ford plug on some (98+) vehicles which we can't use are the green and black injectors on the right.

Just finished my head exchange/ head gasket/ timing chain/ cooling mess deletion and Mustang injector instal. The car cranks but so far no start. I've cranked it over a few times probably less than 1 minute in 4 or 5 tries, I pulled a plug and could not smell or see fuel. How long should I crank? Does the fuel pump only run if the ignition is cycled through start first? I thought I might try to get the pump to run for awhile before trying again. I just can't bring myself to crank away for a long time....

flyinglizard
03-02-2010, 10:43 PM
Does the tach bounce on crank? If not, the crank sensor is not working or you bumped the connection. Maybe do a quick fuel flow check at the starter rubber hose connection.
I did about the same things that you have swapped and it fired right off. I think the new injectors help it run really well. Esp for the 100shipped from the E bay guy.
I was messing with an 84 318 today, and pulled the temp sensor off and it quit. Most of the stuff has to be hooked up and working, for these cars to run.IMHO.

The stockers are these. So there's a small increase in fuel flow with the "new" ones (6.25% more). tjts1, you said you were running the 155 712's? Those look to be LOW impedance units (2.1 Ohm)...is that right?

The new injectors are 4 hole and newer. The idle can improve along with fuel use. The DME seems to adjust to the flow rate just fine.

OK, is there a final, DEFINITIVE answer about needing to modify anything to fit 155 injectors?

It seems that, from posts here, that washers & filing are not needed...they fit fine with everything stock. Is this true? The drawing comparing dimensions indicates that the EV6 & EV1 units indicates that the EV6 ones are ~3mm shorter. Has anyone checked to see if the bottom of the injectors are fully engaged in the lower manifold when installed?

If they ARE too short, the only proper course of action would seem to be filing ~3mm off of the rail mounting points (easy to undo with washers at least).

flyinglizard
04-22-2010, 09:31 AM
Usually, you have to remove the old injectors , one by one as they are stuck in pretty hard, the seals are beat, etc.
The 715s are a little shorter. Placing all 4 on the rail, locking the retainers, ATF on the new seals, slide the ass. in to the intake. The seals fit in the injector cylinder a little higher than the orig. but the seals are not slammed against the bottom. I have not had any issues or do overs. WFM. <<MM

bmwman91
04-24-2010, 07:13 PM
A wide-band O2 sensor lets you accurately read the AFR. Our cars (and almost all others) use a narrow-band O2 sensor. Those are only accurate at the stoichiometric AFR, putting out 0.45V at 14.7 AFR for gasoline. When you are rich or lean, they cannot accurately tell you by how much, only that you are either rich or lean.

I (and many others) are running the LC-1 WBO2 controller from Innovate Motorsports. It has wo programmable outputs, one which is typically used to simulate NBO2 output & feed the ECU. The other can be used for tuning & such.

I'm sorry....what are you splurging on? Those flow exactly what the stock inj's do. I had my 714's sent out and tested because I wanted to see what they actually flowed instead of "internet myth." Well the internet says 192cc's and my test results showed 204cc's. Wow...automatic upgrade of 6.25% flow I guess and I didn't even have to buy a different set advertised at a higher rate. Now you could buy those and then have them flowed and find out that they flow 6.25% more and are actually 216.75cc's. Who knows?

Both sets you're looking at are "re-manufactured" which means they have been cleaned. :)

Have your own cleaned for $16+/ea. at a reputable facility or DIY.

Remanufacture
From Wikipedia, the free encyclopedia

Remanufacture may refer to:
* Remanufacturing, the process of reconditioning products to sound working condition.


Here is a shortened excerpt from :

http://www.pelicanparts.com/BMW/techarticles/JF-Tech/BMW_E30_3_Series_fuel_injector_cleaning.htm

Begin Quote: "With the injectors out, you might see a build-up of crud on the tips. This is usually a mixture of carbon deposits, fuel additives and gas. Use a rag to wipe off as much as you can. Now, get a can of brake cleaner and spray the outside of the injectors and the tips. Use a soft brush to remove any grime on the tips. Now spray a bit of brake cleaner down the inside of each injector and blow them out with some compressed air. You may be surprised at what comes out of there. Each fuel injector has a small filter that collects any debris or crud in the fuel system. Spraying the brake cleaner in there will dissolve any deposits in there.

A good way to clean the inside is to spray cleaner in there, then hit it with compressed air. Keep doing this until the brake cleaner coming out is clear. This is an indication that they are clean. CAUTION: be sure to use goggles when you do this, as the compressed air will spray the cleaner everywhere. You don’t want this stuff to get into your eyes.

Once you have all the injectors clean, get some new fuel injector seals and place them on each end of each injector (Pelican Parts carries these seals for $0.61 each.) Now to re-install them, put a little engine oil on the outside of the seals and press them back into the fuel rail. The engine oil will help you push them into the fuel rail as well as help seal them. Now re-install the retaining clips the secure the injectors into the fuel rail.

Now, go back to the car and plug each injector port with a small piece of paper towel. Now take some brake cleaner and a small brush and clean the area around the injector ports. This will clean the area and prevent any loose dirt or debris from entering the injector ports. Take the paper towels out and look inside each port to make sure there is no dirt in there. If there is, use a small vacuum to suck it out.

Coat each lower injector seal with a small bit of engine oil and position the fuel rail/ fuel injectors back in place in the intake manifold. Now, using equal pressure on both ends of the fuel rail, push down until each injector seats in the manifold." End Quote.

OK, is there a final, DEFINITIVE answer about needing to modify anything to fit 155 injectors?

It seems that, from posts here, that washers & filing are not needed...they fit fine with everything stock. Is this true? The drawing comparing dimensions indicates that the EV6 & EV1 units indicates that the EV6 ones are ~3mm shorter. Has anyone checked to see if the bottom of the injectors are fully engaged in the lower manifold when installed?

If they ARE too short, the only proper course of action would seem to be filing ~3mm off of the rail mounting points (easy to undo with washers at least).

You don't need to modify anything to fit the EV6 injectors. They pop right in without washers or filling anything in. I put washers in mine originally because I thought they were loose the first time around. Turns out I just lost the retaining clips that hold the injector to the fuel rail. I was wrong. I've installed these on 2 more M42 since without washers or any other modifications. None of them have ever leaked. EV6 injectors were designed to fit in cars designed for EV1 injectors from the very beginning. Volvo started using these in 1997 and 1998 across the model range without any modification. Same with ford, Mercedes and a few other manufacturers.
tjts1, you said you were running the 155 712's? Those look to be LOW impedance units (2.1 Ohm)...is that right?
No, the information on that site is wrong. I tested them myself with a multimeter. They are high impedance, 14.xx ohm. I don't think any of the bosch EV6 injectors are low impedance.

I purchased a set of Bosch 0 280 155 700 on eBay a couple weeks ago, and I sent them off to get flow tested. They were all flowing within 2% of each other, and had clean spray patterns.

Yesterday I did my fuel system overhaul (pump, filter, FPR, injectors...need to drop the fuel tank & do the hoses still). The 155 injectors go in without any problems. They are a little shorter than the stock ones, which has been mentioned, but the O-rings are fully seated in the lower manifold. The idle is noticeably smoother with these, and it runs a little better over all (improved mileage too). I think that the old injectors were just crapping out (probably the pump, too). Who knows what was going on with the injector for cylinder 1!

I did have a few minutes of excitement when I pulled the fuel rail with the old injectors. The injector for cylinder 1 was missing its pintle cap...and it just happened that the intake valves for cylinder 1 were fully open (this car is cursed, I swear). I tried to get some little grabbers in through a spark plug hole, figuring the cap broke off during removal, but they weren't grabbing anything. I carefully turned the motor over with a wrench and there was no interference. It runs fine...so hopefully the cap just sort of burned up & went out. It was late and I had NO intention of pulling the head.

Thats exactly my experience too. The ford injectors are a hell of a lot cheaper at the JY (read 5 finger discount) than buying new bmw specific injectors to replace old worn out ones.
I should add that my car passed California smog test (15mph/25mph) twice with the 0280 155 712 injectors so going slightly bigger isn't going to negatively impact emissions results.

Interesting thread, but I'd like an opinion on the short of flow rate I should use.

I have a 91, 318i, and its fuel economy's been a bit shirty for the engine's size, so I am in the process of the "mess under the intake" And my lower intake manifold was of course gummy, same with the injectors.

Since I am in this deep, the concept of swapping the injectors to the 4 pintle variety seems attractive. But I do not know if I should change flow rate.

Unmodified engine, probably won't do anything to it, if I do it would probably just be a chip. Would you bother w/ swapping injectors? Will I realize any benefits going to the 4 hole variety in a factory flow rate?

+- 5% flow rate wouldn't matter IIRC. Even 10% is likely within the design spec for these old FI systems. It's not DI.

In closed loop where the O2 sensor is keeping the AFR at 14.7 dead, you won't burn any more fuel than the stock injectors. I was running 22# injectors in place of the stock 19# and still had improved FE. It only adds extra fuel when the ECU goes into open loop (aka flooring it, high load) where your AFR will enrich. These cars already run way too lean at high load, high RPM so installing 10% or 20% larger injectors simply corrects that issue. A chip, no matter how its tuned, won't resolve the lean condition under high load. At most it can advance timing a little further to take advantage of high octane fuel. The idea setup is chip, large forward facing setup and 22# injectors. A few people are using 24# injectors but I don't have any first hand experience with that.

this pdf from bosch might be useful as its straight from the source

has not only #'s but dates (to the month) of what car came with what injector
problem is its the uk? version. the #'s and dates shouldn't differ much, if any but
theres nothing on mustangs and other v8 fords, under that name at least.
someone help dug up the north american version of this


you'll still have to look up flow rates, impedance, etc.
but i hope this takes some of the guess work out of the sourcing a given injector.
simply print out a massive list for your trips to the junk yard :)
or have someone with a really expensive printer make a single page for you.
if the printer is good enough you'll be able to read font much smaller than this
find one for denso, lucas, etc and we're set

another flow rate site (scroll down).. and again nothing is conclusive. sometimes its by the book, sometimes they test them, :confused: so #s vary a bit.

I've read this thread a few times through and I think this is the proper injector:

http://www.fiveomotorsport.com/fuel-injectors/?itemid=74

The first listing, the 710. I've also seen some people using the 700, but the most definitive option seems to be the 710. The question I haven't tripped over the answer to is whether the same injector part # such as 0280155710 can have different # like 19#, 22#, etc. Many of the posts discuss what # will work with an m42 but I couldn't conclude if a single part number will have one #value.

I feel like I missed something obvious so feel free to duh me.

Just for what it's worth, I had a wideband on my car before and after installing the Mustang injectors. Before, the car was basically at 14.5 no matter what the conditions were. After the injectors, that went down to more like 13.6 at WOT and 14.5ish at a cruise. So it did have the rather desirable trait of running a little richer at full throttle.

How long are this Bosch 0280155715 injectors? My e36 has about 73mm total lenght of injector and about 67mm o-ring to oring. Do the 0280155715 pass my car like bolt on.

I think they can be good with my Dbilas itb and grinded intake-cam setup.

I got now 19.5lb injectors in my car and afr is lean on load and wide open, afr 14.5-15.5

Only at idle afr is around 13.4:mad:

Ok I HAD A HUGE PROBLEM YESTERDAY WITH MY 155 INJECTORS!! WARNING GUYS!

I was at school after driving my car for around a day with my new injectors in. I turn the car on, and immediately smell MAJOR gas. So i shut off the car and have a puddle of fuel under it. The 155 injectors i had (280155700) did not have the slot for the retaining clip to slide into on the fuel rail. Since the injector was just being barely held the clip, the clip failed under the high fuel pressure and the injector came loose and fuel sprayed out. I got new injectors that were a 150 pn with the slot in to hold the clip in. I believe driving without the slots on the injectors is VERY risky because the clips on our fuel rails were NOT meant to clamp that style of injector.

People with 155 injectors beware! I will explain this better with pics soon.

I also have a 318i which I'm using for daily driving duties. Looking to get the best MPG out of it. Installed a COP kit, AFE stock air filter, and a set of the 0280155710 injectors from a 4.6L crown victoria (according to the ebay seller). I'm not certain what the flow rate is since I guess it can vary, but they seem to work well in my setup. I did have some issues sealing them up at the manifold/rail, but eventually after a few times I was able to get them to seat properly. I just filled up my tank for the first time, so I'll see what kind of MPG I'm getting this week. I don't have anything to really compare to because I just got the car running a few weeks ago and installed these injectors then.

I do have 4 of the 0280155710 injectors available if anyone would like to make an offer on them. They are supposed to have 68k miles on them, and I've had no problems with the ones I installed. PM me if interested :)

Left to right: a 155 injector that will work because of the slots for the clip, 155 that WILL NOT fit because it has no clip slot (this was where my problem occurred), stock injector, and a 150 injector with the slots (currently using these)
http://i987.photobucket.com/albums/ae356/balleristic31/IMG00039-20110413-0730.jpg

You can see in this pic how the clip failed
http://i987.photobucket.com/albums/ae356/balleristic31/IMG00057-20110413-1622.jpg

Here is how the clip should sit on the injectors which will hold it securely in the rail:
http://i987.photobucket.com/albums/ae356/balleristic31/IMG00051-20110413-1602.jpg

This is how the injectors with no slots hold it, notice the clip is NOT square and is buldging:
http://i987.photobucket.com/albums/ae356/balleristic31/IMG00049-20110413-1602.jpg

That is where my whole problem was. I may have bought the wrong injectors but the P/N was scratched out on them (sketchy!!) and i didnt know they needed that slot to work right. Jst FYI for everyone!

these are the later 318 m42 injectors. They flow 235cc/min @ 53 psi

but by the flow pattern, they are 4- pintle.

There's a really 'easy' way to tell if your injectors are too small-
scope the injector pulse signal. As long as you're not over about 85%
duty cycle, your injector's big enough for your motor.
If you go over that, or go to that and sit there while the engine starts to
lean out, then a bigger injector's indicated.

'easy' he says.
