the b in b20a5 is a clue.



the all famous b18c is the best candidate.

%26quot;what motor will fit directy into my lude with the same tranny and motor mounts?%26quot; the h22's have an entirely different wire harness and engine mounts. it will not bolt onto your b series tranny. you'll need an h-block tranny. with either engine, you're gonna need a new ECU.1991 honda prelude engine swap?
Why would you downgrade to a b18c? come on. get either the h22 or h23. try to get a jdm one too if you can. just do your own research. ive found that out from building my own car. go read and ask questions on honda-tech.com and hondahookup.com. Get better info and answers there. Here is kids and hear-say.
