Ok so i'm wanting to turbocharge my 89 325i, and i found a very good price on a turbo thats made for 6cyl engines made by CXMotorsports, its a t3/t4 12PSI and i was wondering if its safe to go straight bolt on or if i need to change some things around with the tuning or maybe upgrade other parts so they can handle the extra power. I just dont want my engine to explode but i also don't wanna have to do more than necessary to the engine.
