e34 525i performance help
whats up all
well i heard that i can do some mods on my 525 to build more power but i would rather get this info from you guys, that well know what you are doing
also i know i can never make crazy power from my 525 but i have it and im not going to buy an m5 yet and i don't want to do a motor swap so if there are any suggestions please let me know!
also specifically what intake manifold can i upgrade to? i am not too sure if i can use one from a 535
any help is appreciated
