anyone ever turbo a bmw? I think I found everything I need for a buddies car except for the computer type stuff and this is what I'm wondering if we can work on the stock computer or have to get a new anything...... it's like a 91 or so 325 european spec's

Sorry dude, I know NOTHING about BMW's.

Me either... Except it stands for Bavarian Motor Works...

Well, I should say I know nothing about tuning BMW's. I have friends with 540i's and a few with M3's. But I couldn't tell you much about tuning one.
