i got a 92 e30 318 with the little 4 cylinder...i want to turbo it and was wondering if i could get away with doing a rear mount turbo or at the least mount it down the header near the bottom...doesnt seem to be enough room right beside the head between that and the strut tower....i dont know much about turbos so dont talk shit.just HELP.also need to know what size turbo and all i will need...if you have experience doing this i might just pay to have it done...any help or suggestions are welcome....and no im not doing a motor swap right now...just dont want to..
