i'm not too sure, ive never shopped for internals before... so you just gotta shop around.
If I could, i'd put a totally stock h22 in my car... and that'd be enough for me untill I could afford the supercharger. Internals kinda scare me... besides, I dont wanna push so much boost that I would risk breaking anything anyway...
its totally up to you though... a stock h22 is gonna pull A LOT harder than your f22!!
