only 728? I might be missing something?
Actually, the older generations of H22A's (from the 4th gen, 92/93-'96, '92 was only H23A non-VTEC) where a closed deck design from the factory. The 5th gen Prelude body style swtiched to an open deck block like the B-series engines. I still don't know how strong any of them are, I've never boosted one, but I've heard they are pretty stout motors.
