what would be a direct bolt in motor for an 88-91 crx. The crx has a blown motor and we need a new one but we dont want to rewire and all that other stuff but then again we want a little more power. So if anyone could tell me out of what car an engine would directly bolt in the crx, its pgmfi, I just want to take it out and put the new one in and drive it.

You can use a ZC SOHC, ZC DOHC, CRX Si 1.6. Those are the only direct bolt ins.
