the h22 swap is hard as shit into a 6th gen, have a machine shop redo your entire engine with sleeves and forged internals, run a higher comp ratio and you should make 170hp on a SOHC, it wont be super zippy, more than it is now, and the engine will last forever.

 

h22 ftw!!!!!!!!!! it cant be that hard

 

trust me, it is that hard.

the h22 fit perfectly in a 4th gen, it is a little more going into a 5th, and it's hell getting it into a 6th.
