First off my gf's dad has got a 91si with a b21 in her. She's starting to go through 4 quarts of oil a week and that's starting to get a bit much. So he wants to put an h22 (usdm or jdm) in her. So I need a complete list of parts for him and as many resources as possible. I need everything from electrical, mechanical, to suspension.

This is what I know so far or think I do.

1. Engine
2. Mounts
3. Harness (Boomslang or Rywire)
4. ECU (unsure which one)
5. SRI or CAI (intake)
6. Radiator (unsure)
7. Transmission (unsure if the one from the b series will bolt up with adapter plate)
8. Shift Linkage (If I have go to with a different transmission)
9. Axles


That's the list of stuff I think I need. But I am also looking for websites for him to read on so he can decide if this is really worth it or not. I've got a 5th gen prelude and I really only know about stuff for those cars, but 3g's I am even more of a newbie. Please do not tell me to continue searching cause I really have looked around, I'm asking cause now I need someone to help me out by finishing the list with great resources to read on. Thank you very much.

 

Here is a link to 1funryd s h swap, it has lots of pics and goes into alot of detail. He
swapped in a h23, but alot will be the same for a h22 swap. Hope that helps a bit.
