M42 Turbo

[RedReplicant]

Are you on the stock ECU? Or, rather, what is your tuning situation?

[Esprit]

Yes, it is a daily driver currently in Buffalo NY. He is attending UB.

Is this car your dd?

Wasn't it "Maximum Boost"?

I think he got a mix up between "maximum boost" and "supercharged" :P

dpm:

We are running at 170 to 180HP estimated.

Last weekend he cut 4 seconds off his lap time and is now turning 2:28 at Watkins Glen.

Read Corky Bell's book. It's cunningly entitled 'Turbocharging'.

8 psi really doesn't stress the engine any more than N/A
as long as it's done right

M42 on boost sounds like fun to me... one of these years...

Mitch will be running in the Reisentoter Region PCA event on July 25-27. Once again at Watkins.

The car now has a 6 point Safety Devices cage, Momo racing seats and harnesses. We will post a link if we get more video.

How much boost, MikeW? And what turbo?

Jake's Turbo kit in my 1991 318i:



I could not be more happy with the Kit and I don't think Jake ever took longer than twenty minutes answering my emails, and there were many! Installation was a breeze had I not been such an idiot.

We inverted the stock header (cost=0) and used a 1992 Saab 900 turbo and intercooler from a parts car we had. With 24# injectors it runs 8psi on the street and track with no problems for 4 years. The engine had 138K miles when we began and now has approx. 180K.

I have Jakes kit and 175K on my car. So far so good at 9psi. I would go that route and save the hassle of putting all the parts together. I did do a lot of other stuff at the same time to try and keep it reliable. New fuel hoses, coolant hoses, VC gasket, vac lines. It seems like if you get a good M42 they run for a long time.

Take your budget and be prepared to double it. At minimum I strongly recommend refreshing the motor. I got around 6 months of hard driving on mine and now am having to address some issues I should have done in the beginning. My car has over 230k miles.

Your M42 build is crazy nice! Just got some motivation on my'n upcoming build! :D
