are there any mods that can be done to this engine to boost it's performance,or not???
if so what can be done???? turbo,,,supercharger???

ive been told that they do make a stage 4 turbo (a monster) for the f22 now but i am not positive. this i just what ive been told by fellow f22

with that big of a turbo you will also have to get your engine resleaved...so you might as well swap an h22 and that way you can start with alot stronger engine
