Hello. Recently just upgraded from an 4 cylinder car. Now I have my 525i which is an inline 6, this is my project car. So of-course now that I have 2 cars, I will now make my i4 my everyday car, and my i6 my speedy car. My question is what upgrades can i do to my 525i? Its healthy and still has a lot of life in it. I know I can turbo it or supercharge it, but Ive heard that bmw's can mix and match parts ... how does this work? Give me some ideas to make my car faster, cheap unique methods are greatly appreciated. Also my car shakes a little bit when my car is idle, when it starts, and a little bit when it drives. Not like a crazy shake but like an engine running shake.
