i m going to be rebuilding my M50 motor from my 325i to turbo it in my e30 325iS and i was just curious, while I have it out and i am in the process of building it what would be the best set up for a turbo'd engine, i planning on running any where from 15 to 25 psi of boost, i have yet to build a turbo engine and dont know what I should get for it besides forged internals, and low compression pistons, i was thinking 8.5:1 compression ratio maybe from 7MM valves to 8MM, any advice would be greatly appreciated.... please be kind lol
thanks
