I just received the 3.2 that I am going to install in my '95 m3. I am wondering about the exhaust manifold. Does anyone know which holes need to be plugged on it? Does anyone have any pics of the mods? I read there is a stainless bolt that I can get from BMW but when I asked a nearby dealer about it the guy just looked at me like I had something wrong with my face. Thanks in advance for any help.

why is that the platform guys want for more horsepower.. DME is easier to program?

i have Dinan CAI, MAF, BBTB, and reprogram.. im going for some serious power in the future going all NA because I want a reliable street driven car, that will be used at the track also....

just want more info and whats all involved in the process

You don't need to go obd1 just get the sunbelt cams and you will be gtg . The 95 m3 guys do it because well might as well put a 3.2 in if you blow your motor. The clubracers have been going obd1 because obd2 software has not been available for the sunbelt cams. Stay obd2 and go sunbelt cams. You will put down around 270rwhp

anyway to get to 300rwhp NA without rebuilding the internals?

Nope. Also a 300rwhp NA built s52 will not be a good street motor. There is like a 20 page thread on this very topic. Worthy of a read
