Well, If you swap in an h22, since it's an H-series, I don't think they bolt right in, you'll need specific motor mounts for that swap. I think Hasport might have them. If you want vtec, jsut do a Vtec head swap, or save yourself the work of conversion and buy a GSR or even a B16 VTEC motor. You could probably pick up a B16 out of an 99-00 Civic Si somewhere. They aren't really that great of motors: only 160hp, but it's got Vtec, and potential for more power...
