I've heard that the H22s come out of the prelude and that you should get it from around the same year as the accord so that it will match the chassis easier. I've got a 95 accord. So what year and model preludes would I look for to find an H22 engine. And what brings the H23. Is the H23 the non vtec version? I've been thinking about going to a few local junkyards and pulling an engine and tranny to build it up.
