f22b1 coupe
Junior Member
Has anyone put an H23 (non-VTEC) or an H22A1(VTEC) head on an f22b1 (accord ex VTEC) block? Obviously I'd have to change ECU's to go non VTEC, but would I have to change ECU's if I stuck with VTEC? I'm assuming either way I would, but I just need to know what parts/processes are involved. And would doing this, changing head and ECU, make the engine's performance equal (roughly) with the prelude the head came off of, or would it not be the full hp difference?
