ive been looking around and i cant seem to find much of anything....

 

look for guys who had h23 preludes and then swapped in h22s. H23's are cheap. I got mine for 250 plus 120 for shipping off of ebay. I've slowly been rebuilding it, so far, the only problem is lots of carbon build up and possibly new piston rings are needed. Be careful though, there's been an abudance of h23s with spun main bearings. I'm replacing mine just to be safe....
