If you didn't buy the H22 yet, I would strongly advise against it. Just boost your F22, those things are bullet proof.

 

From what i've heard, the h22 "drops in" the 91 accords. You might need a few changes on your harness, but nothing major i wouldn't think.
But i definately agree with sinister...save your money and just boost the f22. You'll like it so much more

 

The thing you need are very minimal i think the only thing that needs to be swapped is the coil, i think the h22 uses an external coil or the other way around
