prelude type s engines (the ones with ATTS) have a different block casting to all other h22a's. im trying to remember back to when i was going to do a h2b with the QSD kit. for H2B setups the b series intermediate shaft wont bolt on as the rear of the block is different. there is a way to get around it by modifying the block but i cant remember what it is exactly but there are people who've done it in australia and its worked.

id try to source an h22a euro r. they are the most powerful from factory, have the good intake manifold and u can sell off the lsd gearbox
