well the problem is i already want more power. I was seriously thinking about turboing it. the engine is very clean and runs strong. i was also researching stroker kits, but theres some big money in that, and for the price could just do an m3 swap.
i already have 2 1/2 piping with a cold air. There isnt to many things i could do after that. other then changing the injectors. or is there?
