kornbeefy s4
i have a b5 2.7 twin turbo s4. so far it has bin remapped and has a replacement k&n air filter. i feel i am only skimming the surface of full potential of this engine. i would greatly appreciate some advice on what steps 2 take 2 turn my civilised saloon into a bit of a beast. are k04's the only way up or are their alternatives. do i nead larger intercoolers and fuel pumps? i am unsure of what breaks 2 upgrade 2 and suspension.i am working to a budget but i understand that rome wasnt built in a day.
