Hey guys, I, like everyone here, am in love with my e34. It's a 92 525i 5spd M50 NON-Vanos. As you can see I'm not dealing with a lot of power. I was thinking of a major project and I would like some feed back. 1. An engine swap for a M3 engine. Question: What year M3 engine could I put in my car and how much do you think it would be. 2. ActiveAutoworke Turbo Stage 2 Generation 3 upgrade. It rockets the M3 0-60 in 4.2sec. Imagine and E34 pulling up to a Z8 and keeping up with it!!! Any extra information you could give me would help. Thanks guys.
