Hey, I'm trying to do a swap with a remanufactured engine. I have a 1992 Prelude Si with the H23a1. I want to sawp a remanufactured H22a1 into it. So I found a good one, but it doesn't come with anything like the Oil Pan and Valve Cover... ... etc. So I was wondering if I could use my H23 oil pan and parts or will they not line up? Any help would be great. I've used the search and haven't found anything. Also if anyone knows a place to find Complete remanufactured engines let me know. That would simplify this a lot.

You can use the oil pan, but not the valve cover.

 

alot of the parts between the two are interchangeable im pretty sure oil pan will work and the h23 pan is proly bigger than the h22 pan which will lead to cooler oil as far as the valve cover i think it will fit juz unbolt em and give it a try but they proly should its like interchanging a b16 valve cover with a b18 i think it ill proly work my boy had an h23 in his 92 and he dropped in a h22 for a while he didnt have a tranny for the 22 and he threw on the one for the h23 bolted rite up with no problems
