asubimmer's turbo thread! [/thread]

[asubimmer]

I'm pretty much done w/ the research and the turbo will be on shortly.

When I first bought my 318is I didn't know what I wanted to do about the whole engine thing. I thought about the x50 swap but I decided that that would compromise the "feel" of the 318is. Sooo I decided to go FI. The M42 is a VERY under-rated engine by fellow bmw people as you prob know.

Well enough of the background here are some of my parts:
I sold the t3 for a gt28rs. I figured dual BB and ceramic blades, why not.


Next is the FMIC:

This setup I am working on will be 10psi.

If you have any questions or comments PLEASE ask them I will be more than happy to explain or help you in any way I can.

[StreetSpec_iS]

very interested to see this progress. keep us updated and good luck.

what is the front mount off?

i have just found out that i have a pre-fabbed m42/t28 intake manifold available to me, so once again, i am considering the turbo route. However, where i live it is very illegal and as such would void any insurance policies. so yeah, we will see.

[asubimmer]

its an alumin fmic from ebay...we'll see how good it works. It actually looks like its built really well.

[bmwman91]

You are using a FMU...is that a manifold pressure controlled fuel unit? While it will work for low boost apps, I HIGHLY suggest going stand-alone. I ran MegaSquirt on my 1st 318iS, and have yet to get around to it on this one. Awesome project though. Keep us posted!!!

[asubimmer]

yeah the FMU is a mechanical fuel booster. For low psi apps it is more than enough so thats why I am using it till I go to higher psi's. I will get some pics of the FMU when I get back to school next week.

Alot of people plan turbo projects, even buy parts. Sadly those that complete the project are few.

Prove me wrong bitch! I want to see it!

Prove me wrong bitch! I want to see it!gladly, I know tons of people do that but I am going to do mine for sure. I love the 318is it just needs a little more power, ya know.

[mkovarick]

Looking forward to seeing this.... I have plans to turbo my 318is, and believe it can make a nice amount of power, but it has 140k probably hard driven miles on it. This would be my 5th turbo'd car if i do it :)

Anyone have any links of other turbo'd m42's? Im interested to know in the power/reliability of it. I think i would be dissapointed if saw anything less than 200whp.

Are you planning on lowering compression or touching the motor in any way? Give me some more details, im interested in how you are going about doing this.

And good luck :)

[e9nine]

If you build it right, it will be reliable. If you drive it like a maniac it will disintegrate. If you half ass shiet, you could end your smiling parade very soon. MOst important of all, if you get cocky with the newfound power, you can hurt yourself. Just be safe, plan and do it up!!
I haven't built a turbo myself nor owned one but I have driven, ridden, seen many. Either high compression, low boost or lower compression and go with higher boost. I have no experience and all my ideas are just what I have read and not tried so you're better off not listening to me.

[e30_kid89]

hey guys i am also looking at goin down the turbo route but so far all the ppl i've asked give me funny looks wen i tell them the m42's compression ratio.. so asubimmer r u gonna give it low boost with stock compression or lower the compression then high boost? if you do low boost with stock compression i promise i will turbo my m42 by the end of this summer:) of cousre i will prolly use all the same parts as your set-up as well if urs goes sucessfull...good luck man!!:D

[asubimmer]

yep thats the plan low boost stock comp ratio, then rebuild low comp pistons etc. and high boost.

[kowalski]

got an update for us?:)

[asubimmer]

well, I am still collecting the last few parts. I am hoping to start when college lets out for the summer but its creapin up fast.

[asubimmer]

well I have been messing around w/ ideas about what to do w/ the whole turbo manifold thing. I have stummbled upon something really big I think. I don't want to spoil anything but it may be easy for you guys to get a cheap turbo manifold real soon ;)

I'll keep everyone updated.

[B2thazizza]

Keep us on the update i wanna do this to my car

Have you seen this manifold? Any thoughts on it or the company, they seem to have a good reputation with the Honda guys. $600 doesn't seem too bad if it's well made, but if you've found something cheaper.....:)

[asubimmer]

yeah thats the only one I know of, I am working on something else though. Its still w/ a pretty big name and would be a lot cheaper hopefully.

[jfdublyu]

can i get some more details on the FMU you're using? specs?

[Tvan]

what are you going to do about the M42's inherant lack of knock sensors?

[asubimmer]

what are you going to do about the M42's inherant lack of knock sensors?thats really not a problem, although its a common misconception.

even if something happens to my engine due to the extra strain, I'll be building another m42 for high boost. So I'll just have to hurry up and finish it if its not done.

[///Motorsport]

hows it coming? and whats this manifold deal? most of us are quite interested..
good luck!

[M42boy]

That's where I'd be concerned. :eek:

No protection against predetonation. Better run some good gas or some octane booster. This will be your best friend! :D

Turbos love Tolulene... It's basically paint thinner. You run it in the gas tank to avoid pinging (or your motor grenading!).

[asubimmer]

I have been talking to a few local companies about a turbo manifold lately. HOPEFULLY we can get something going in the timeframe I have. I am REALLY getting anxious for boost. I just want to get it on now :(

[bokes]

Turbo m42 here: http://www.ticco.com/
he says he's using an m20b25...

[thumper3ld]

he says he's using an m20b25...

Yeah but if you look at the older pics, it looks like he did turbo the m42.

[Euro Nation]

Are they going to be building you this turbo chip based on the idea that you're using an FMU? I'm still really interested in making a turbo chip if you weren't so far away :mad:

We'll have a final version of our N/A chip very soon though :D

[bmwman91]

Very cool so far. Keep the updates rolling!

just subscribing to this thread!

[asubimmer]

well guys once again another setback :( My welder is REALLY backed up at the moment. He said it would be at least a month before he could think about it. All is not lost though. I'm just going to take the manifold to Korman and have them shoot it up for me, I should have used them in the first place but I know they have lots to do themselves. I hopefully will be going back to greensboro next weekend to do the install. I just hope my professors don't try to set me back again. It will be a long weekend but I plan to come home on fri and drive back to school sat w/ the turbo on. Cross your fingers guys!!

[Deutschbag]

School sucks ass, I can't wait to work on my car now that I'm graduated. Gotta get a job first though.... anyway can't wait to see if you're successful in this undertaking, good luck!

[DZick]

Please keep us updated, these setback are killing me... lol

[asubimmer]

Please keep us updated, these setback are killing me... lolyou and me both.

I am prob going home this weekend. I'll replace my guibo and having the manifold welded. I'll prob cut the oil lines to fit while I'm at Korman.

[JiXer]

Whats the status?

[asubimmer]

Whats the status?
well the manifold is still up in the air, but I have all the other parts. Just waiting to install once I get the manifold situation finished :D

[vjlax18]

Did you ever figure out the manifold? The factory maifold may work, but the flange will have to be drilled out, etc. In my case, I'm looking at making a maifold that sits the turbo about 2" further forward then needed. Eventually I'll be moving the engine back the same 2" and the shock stock is in the way.

[asubimmer]

I got the COP conversion done yesterday and I should be getting a manifold for a turbo m50 soon. I think thats going to be the best bet since they are tubular and it will be easy to modify it to fit our engine. I'm waiting on MS but I should be running it in the near future :)

[nobrakese36]

Hey m50 and m42 manifolds have the same spacing/bolt pattern, so you could just remove two of the ports(tubes) and weld it closed,this should be a good solution to your manifold problem.

exactly ;)

Im thinking about foing turbo this any good

a gt28rs will make good power with less lag. GT series turbos > T3

you can find them on ebay pretty cheap too.

Didnt you have like 12.5:1 CR? Getting different pistons?

[vatos_p]

I personaly think that T3 is al litle bit small for m42 318is , because all the past year i am doing a reaserch because i am going to put a turbo into my 318is... i am going to use a Garrett GT 28/60 , v-mount intercooler , and everything else handmade by me and my friend... ( we are crazy people - we do turbos in our cars - till now we have made 3 cars you will not believe )... for fuel managment i am going to use a " splitsecond additional injector controler for 4 injectors ( it is programmable via laptop , you make a map while you drive ) with handmade intake ,and 4 extra injectors ( it is better than change the factory injectors with bigger and put a chip into the cpu because you can't make changes anytime you want and you can program it yourselve ) , i will put an oil cooler frontmount... hopefully i will begin my project these days , i will take photos of everything and let you know about everything....

[Gunni]

vatos, can the split second kit control ignition??

If not check out the SMT6 unit, it can and will work great on a M42, also you can have the extra injectors work depending on boost, and retard ignition depending on boost as well

[nobrakese36]

Yes, if i lower my compression with a MLS HG it should be around 10.2,though.

[asubimmer]

vatos p, the 50 trim t3 looks pretty perfect on the m42 when I mapped it on the compressor map. It should have full boost about 3k if not 2.5k. Although a t3 would be good for fast spool, if you want huge #'s you prob would want a bigger turbo but the tradeoff is lag...

The turbo just depends on what you plan to do w/ your car and your goals.

[vatos_p]

no splitsecond can control only extra injectors

[vatos_p]

I Am Thinking Of Using The Smt7 , It Has All The Goodies Of Smt6 But Also A Boost Controler...

Do You Think It Will Work ?
Please Tell Me If Anyone Has It And Have Worked It To Know More Details...

And Thank You For The Tip....

[Gunni]

I haven´t used a SMT7 for boost, but the settings are real easy,
the SMT7 should meet all your needs and then some,

I´m almost finished with my m42 swap, when it´s done, I´m going to alpha-n the engine using a SMT6, will report back when I get going, was going to use a MAP sensor but decided it didn´t matter as neither measures air really,
a O2 will be there for closed loop after the re-tuning

[asubimmer]

well I have been hush about this for a bit now. Its been slow w/ college and work. I have the manifold as you guys know. I also picked up a dual BB and ceramic bladed gt28r ;) I am getting the MS1 v3.0 and a wideband o2 soon. I am thinkin about NGK's new wideband. I need to get the MS asap b/c I would like to get it up and running before I get the turbo on to make tuning easier.

[asubimmer]

well w/ all the new stuff I decided to start a new thread since a lot of the stuff in this thread isn't conserning the new plan.

please see http://www.m42club.com/forums/showthread.php?t=2005 for the new thread!
