Im building my e30 into a dedicated track car and needed some help as far as which engine to choose. I realize there are probably a million threads like this. Ive read through most of them but I havent really been able to come to anything conclusive.
I currently have an opportunity to pick up an m52 from a 1997 328 or an s52 from a 1999 m3. Im also getting a holset hc1 turbo really cheap from a friend. Which engine would be the best option with this turbo?
Ive read that the m52 engine is better at handling boost, although Ive seen quite a few turbo s52.
Or would my best option be to save a little money with the m52 and get an s52 crank?
Thanks for the input!
