Hi Gang,
My name is Kings. I'm from Australia, Sydney.
I just wanted to tell you guys about my favourite girl. I've had her for 5 years.
220,000km
K&N rampod air filter, racing dynamics racing cams, delco engine management system, intercooler, WRX garrett turbo, 2 and 3/4 inch exhaust, front camber kit (neg 3), 4 piston wilwood brakes, short shifter, e36 cooling fan, redline lifted to 7800rpm, 5% tint. turbo water and oil cooled, transmission oil cooler, 16inch racing dynamic wheels.
Standard compression, no engine rebuild just yet as she doesn't blow smoke.
If anyone wants to know anymore let me know.

pics! what color?
-
I forgot to say that the suspension is H&R springs mated with Eibach sport shocks and strut braces front and rear. And the motor now has a single mass fly wheel.
It used to be supercharged but the rotrex supercharger blew up after 4 months. The turbo has been in there for 4 months and hasn't missed a beat. Better fuel economy as well.
I've attached a photo.

ohhhh-k.... you've got 24 hours to post some more details of this setup ...or else I'm going to photoshop tres-fey rainbow-colored parrots all over your car. :D
we need more info on both the rotex setup and your new snail... you can't just casually throw that in there and not expect that it won't drive us nuts... enquiring minds wanna know!!
thanks man, and big welcome.
car looks great too... shame to cover it with parrots.

I'd definately like to know more and see more pics.

love the new sig there jay :)

I had a rotrex supercharger put in begining of last year. It cost me heaps, I had to get a new engine management system, I pissed off the AFM, kept the rest of the engine as standard. I completed about 6 race days a few top speed runs and then things started going a bit sad. What I didn't know was that the rotrex supercharger doesn't like rpm above 6000rpm. So the internals gave up one day whilst giving a Monaro or Pontiac GT a run for it money. It caused the engine to stall and locked the rear wheels. How embarrasing. I was running about 10PSI which is what most M42's can handle without stressing and decompressing the motor.
So it took me another 6 months to save up for the turbo conversion. I was hoping to get better fuel economy and a more reliable car. Same boost and no lag. Its even delivered the same way through the RPM range. Its just when you don't have your right foot jammed down it doesn't burn the fuel. Where as the supercharger did. For those of you that don't know the supercharger produces power directly related to the amount of RPM. The turbo is related to the amount of exhaust gas coming out of the motor and throttle position.
With the turbo I have boost from idle, I have full boost at 2000RPM. Its a really happy car. I can drive it all day under 3000RPM and it like a 325is. I can pound it and leave everything but exotic cars for dead. I want to put my 318is badges back there just to upset the 325i's out there.
Oh and my registration plates say E30M42.
I don't know what else to tell you guys. So ask away???

You guys gotta like it since its our cars. Some pics of your car and engine bay would be nice e30m42mtech. Cant think of any questions since I am not very mechanically inclinced, but I'm sure lots of people here will ask.
-
Definately details, I want some info on the harmonic dampner.
-
Sheepdog,
I think your talking about the pullies at the front of the motor. For the turbo all the pullies are still the same. I've just had the fan removed from the front. I had an E36 electric fan put in with the fan shroud from the same vehicle.
If your talking about the single mass fly wheel. I got that from a 325i, i think? I was done when I had my clutch changed. It made the idle a little less smooth, but you wouldn't know unless you looked for it. Plus the cams make the idle ruff. Because the fly wheel got changed, the mass of the fly wheel reduced by 2.4kg's. So the car became a little harder to get off the lights. But the upside is it gets through the RPM's alot quicker.
I hope that helps sheepdog.

No, the harmonic balancer/dampner on the front of the crank (the pulleys are mounted to or in front of this, it is basically a big chunk of metal). They tend to expode at 7200 rpm.
-
Wow, 7800 would be fun w/ an m42. I'm anxious about the harmonic balancer also. It's right behind the crank pulley as sheepdog already noted. Just a big chunk of metal same size as the pulley usually.
-
I want to see more pics :).

I guess not. He said his was stock...

me too! :D

have you any pics or any actual examples of one doing so? what exactly explodes at 7200rpm? this has been posted around this forum a lot, but i've never actually seen a dead balancer or engine as a result etc. (and know of plenty of people running high rpm through our engines). ive questioned this loads of times, but haven't had any concrete examples of what happens. As we have a strong forged crank with hefty counterweights, and having had the pulley off the car and taken a good look, i'm still no wiser really. its potentially not as strong as other designs (e30 m3), and there's potential for the hub to come away from the damper and pulley i guess, but i'd imagine that would take some serious abuse - like 6 M8 bolts sheering off. likewise the rubber for the VR wheel could disintegrate, but that would be through neglect rather than bad design.
-
woah, don't jinx yourself there fella! :D
I've asked around about this (a lot) and basically gotten the following:
this issue originated re: older M20 engines, particularly w/work on ETA engines... it started with a statement by a pretty well-known engine builder saying that the 'E30 harmonic balancer' fell apart at 7200 RPMs... this btw, turned out not to be the case.
it kind of mutated from there, and was then repeated by writers like our esteemed mike miller, and like many things on the internet, sort of took on a life of its own.
naturally... so I guess I'm now well in the process of jinxing myself... but I'm planning on revving my 'lil M42 to over 7500 rpms so one way or another, we'll find out.
-
I'll get back to you on it it. I'll get some photographs for you. I know the part your talking about. I'm not sure if it got re-engineried or what. My cars not always with me as I'm always driving a work car. I'll get some photo's of them as well.

I have heard of chip makers trying to go higher and havingthem shatter, how true. I do not know.
However, someone on Bimmerforums does have one that has been up around that rpm and it has cracks in it.
I also have read that the dampner goes at 7200 and above 7800 or so something else happens, lifter collapse or valve float maybe? Been a while since I read it but it was written by an engine builder.
There are a few companies that will make custom omes for higher rpm though, I am just curious what was used. I was not trying to pigeon hole anyone.
-
haha yeah you're right i shouldn't jinx myself! I just want some good info on this to see what should be done. i'd considered using the later design pulley, but without being too sure what's wrong with our original i'm not sure how its any better. i know the S42 has a serpentine belt and all the pulleys look different to the production car. maybe i'll add a serpentine belt upgrade to my to-do list. tbh as its my daily its not going to get revved too highly and it still has hyd lifters and standard springs for the moment.
i couldn't find any info on the cracked one on bimmerforums, you got a link?
-
welcome aboard Kings. who did the fabricating for the turbo and brakes? ALS?
more pics mate, more pics. ;)

Nope, it was a while back.

Hi guys,
The harmonic balancer is a custom job. I've taken some photo's of it and a few other pic of the car. I hope you find all the info your after from the pics.
Sorry it took so long. My work some times keeps me busy 24/7.
-
I don't get to drive my E30 very much any more. I miss it. I get to drive it once a week if I'm lucky.
Most of you will think I'm spoilt. And I probably agree that I've taken my work cars for granted. But that raw feel from an E30, you just can't beat it. Thats just my opinion anyway.

You have gone throught a S/C and a turbo! I love your style!! Now your daily driver work cars surely make you appreciate the raw beast of an m42 no doubt.

Kings,
I know you posted some info earlier about your setup, but could you please post a DIY thread, or some detailed instructions with parts, tools, photos, approximate difficulty, and time to accomplish this project?
Not sure if you've noticed but there's a lot of us who are looking forward to improving our M42's. There's a lot of projects out there, but many of them are still in progress and incomplete.
I must commend you for a nice job. Your car is an inspiration to many of us!:)
Regards,
Chris

I'm sorry if I gave anyone the impression that I did this myself. I didn't, far to complicated for me. Things like mating the Delco engine management system to the original wiring harness of the E30, tunning the engine management system and making sure the enegine makes the most amount of boost without blowing the engine. Its still runs the original high compression.
So the bottom line is, I left this to the expertise of the best tunning house in Sydney, ALS Performance. No they haven't paid me to say this, I paid alot of money for this, but it was worth it.
There is a guy that got his car done there just before mine (E30 318is) and he
is getting about 240-260bhp at the wheels. A little bit more than my 140bhp. At 140BHP you starting killing Monaro's or Pontiac GTO's (6.0L V8's).
So back to your question. You guys want to find out more, and I want to share if with all of you. I think the best bet is to ask the questions and I'll try and get you the answers.
-
woah hold on a second...you say your friend is putting down around 240-260bhp and then you say "a little bit more than my 140bhp" ...thats pretty much stock! are those the actual figures that your engine is producing???

Something is amiss if he's smoking Monaros with his car. My guess is the conversion factor (the hp conversion will mean he has lower numbers prior to conversion to US hp)and perhaps him mistaking whp or bhp could be to blame?
-
Love the car, the country, and the people. What track is that. It's a real nice looking facility with that banked uphill left hander. Probably a challenge to carry speed out of. I also have a diamondschwarz 318is. I think the color is a natural. I have been surfing Delco engine management and Kalmaker software on several Australian sites. I had no idea anyone was using it in that fashion. Interesting.

Guys, factory is 136-9bhp at the flywheel. I said mine is at the wheels. The other guy is 240-260bhp at the wheels. You'll find factory output at the wheels to be about 100bhp (if you still have good compression).
-
ouch 100hp stock. now i know why my 9lb flywheel made such a huge difference. i need to dyno
