I hope the time has come for me to replace the d16a6 in my 89 crx si. I found an h22a from a 94 prelude with 65k miles on it for $1200. I've read of some people putting h22a's in crx but I've heard of some problems with it. I was wondering if anyone could fill me in on what types of problems I'll be running into and maybe anything else a non-expert wouldn't know about.
