ok i disagree with you guys talking about a swap from the f22a to the h22.. the f22 is the ideal motor for a turbo because of its low compression at 8:8:1. where the h22 is like 10:8:1.. so if i were you i would put a small turbo running 8-12 pounds of boost and that sucker will fly also the f22 has a bullet proof bottom end so you dont have to modify the engine any..
