i had a few q's about the b18c5. i was wondering what you can do to it,(make it faster, more hp ect....) as in internal wise. I plan on doing a b18c5 swap into an old Mini, so i was wondering what i could do to make the numbers go up, but at the same time, not add to many things inside the engine compartment.... if you want reference on what i plan to do, superfastminis.com explains. i know for sure that a supercharger or turbo will not fit. so what are some of the other things i could do, as space is a big issue even installing the engine it self it space conservative.... please let me know. thanks.
