I wasn't talking about just that though, just about everything you said was wrong and you seemed so confident about it too. There is no F23A1 in Preludes the F22A1 sohc-non vtec, was in 4th Gen S preludes and it had 135hp. The H23A1, non-vtec has 160 HP. The H22A1 (VTEC) has 190 hp. And the compression oh the H22A1 is 10:1. F22B1 sohc is a VTEC engine that came in Accords and it's CR is 8.8:1.

As far as your other question, I don't know the answer to that.
