If you're good at machining and such you can take the DOHC VTEC head off of the H22 and place it on your F22 block. This setup made like 180whp and 160wtq. You'll need to check the HondaTech forums I think? Check the Accord section, a guy named bubbarub or something will know more about this.

And since you'd be swapping heads, you might as well rebuild the block and head for a turbo. Turbo a frankenstein and you should get 300whp.
