So i own a bmw 528i 1998 the motor is m52b28 .
im not looking in to boosting it not now at least
i want to build it up just dont know where to start.
some ideas? i know parts from the m50b25 should give performance gains and cold air intake does some good. any suggestions?
i have it straight piped almost all the way to the end. it was meant for a beater but i like it to much now to beat it up.
