Exactly. H23/H22 is a pretty worthless combo. Not only will you get the same problems associated w/ other frankensteins (which can all be worked out, naturally, but it is time consuming), it puts near the same power to the ground as a bone stock h22a. Like Andy said earlier, it's not like the ls/vtec. Whereas many things are different between the b18b and the b18c, really the only thing different in the block of the h23 is the crank (not talking about rods/pistons and it's lower cr) and the lack of oil squirters. You can buy h22a's so cheap now-a-days that it is just a waste of time to be inventive w/ something that will really get you nowhere.
