I just recently bought a 93 325i (auto tranny). It has 130,000 mi. I want to make it fast but i don't know where to start. I was thinking of buying an m3 exhaust (my muffler went out), a Dinan cold air intake, Dinan Transmission Chip, and a Dinan Engine chip. If anyone has any suggestions to what i should do, i would really appreciate it. Also, if anybody is selling anyone of these items, pls let me know. I am also looking for a good deal on 17" AC Schnitzer type II's and was considering a 5 or 6 spd transmission. Does anybody know how much the transmission would cost me including labor?
