BMW designs these things to give just about every ounce of power they can give right out of the box. Trying to squeeze more gets REAL expensive real fast. I do know that in its stock form my 87 325is has eaten many a tuner honda live. The inline 6 gives uber torque for its displacement low in the rpm band and the car will wind to 8g's real fast under load as a result. Most small 4 bangers don't make any real torque or power until 6-8 grand and by then the race is over. Try it stock and with stock exhaust for a bit (big pipes rob torque and therefore power) you may find that only a few mods (like a flowmaster muffler only and a chip) is all you really need to beat your buddy's car (and it'll eat him alive because you're doing it with way less.....on paper at least). Also cold air intakes, generally a waste of time on these. They already have them as well as true dual exhaust, in a 6 cyl. Haven't heard of az bimmer motor werks. There was a bills beemers over on mcclintock, they royally pissed me off once and I never went back. Do all of my own work as a result.
