Turbo setups caught a bad rap over the years because of people being really stupid... for instance, when I was younger and didn't know jack shit about cars I had a "knowledgeable friend" help me turbo my miata. He, I shit you not, tuned it "by ear". Amazingly enough it lasted a few thousand miles before blowing up.
Step 1: Always rock a wideband, even if people tell you "you'll be good, I've got a sweet ass map that works great on my car, use it".
Step 2: Let off the throttle if you start getting a stoich leaner than 14ish:1
Step 3: No mystery step
Step 4: Profit
Just follow these steps (especially 2) and you'll avoid most of the disasters that could cause you worry.Comment

I was considering selling mine and getting a 325e, slapping an I head on and going for boost. The only thing is that I wanted to do this to my car because it's already fucked up. I'd hate to buy a straight body e30 for what I plan to do with it.Originally posted by Alpina View Post
And guys, I'm deciding wether to boost or to swap, not what to boost after I swap it haha. Kinda kills the budget aspect of it.1991 318i SedanComment

Im confused as to why you think turbo plumbing is expensive? intake shit is dirt cheap, exhaust is cheap if you can weld (i cant weld but i made that shit happen because jew), jakeb has m42 turbo mani's that im sure are affordable. If tuning is your biggest scare then have someone else do it. Easy as that. Or do jakes kit. Ive heard nothing but great reviews and if youve seen any of his builds you'll know the quality is top. After this winter Im thinking about getting an m42 car to dd and Ill definitely get his kit. den i haz twin m42t's :)Comment

I was only nervous about tuning because of how green I am to boost. After sleeping on it I'm actually wanting to play with a tuning program. Am I going to be disappointed with the power I get from an m42 for the price?Originally posted by MF DOOM View Post1991 318i SedanComment

I helped a friend with a cheap M42 turbo build some years ago, stock internals except for M50 non vanos 135mm rods for super low compression :) He gave that engine a real beating and it worked great! I think it was like 230whp due to too much back pressure, otherwise 300whp should be fine.

Still can't make up my mind. It's basically a cost battle at this point. I've heard of a member(espirit I believe) who did an inverted header turbo and seems to be happy with it. Is this something that I should consider or would I be better off buying a kit or going v81991 318i SedanComment

V8, every single time.
It doesn't matter what you do to the M42, it will always be lacking cylinders.Comment
