ok Chris i know i haven't spoke up in a while but ill throw my two cents in there... I say you build a G23.... but do it like a h2b so you keep the b series tranny you already got! in case you havent seen it you take the h22 head and put it on the f23 bottom end.....the f23 has steel sleeves so you can boost it or you can throw some k20 pistons in it and push like 12:1 using all stock parts. i think this is the site i was reading about it on
