what engine is this. 89 honda crx.

If that is the original engine, look at the serial number/vin, the first 5 places, indicate the engine. On the outside, look through windshield, driver side corner of dash. The engine iD starts with D.

sorry should of mentioned this is not the original engine.

Sorry, I can't help you. I guess you could look at cylinder head or block casting numbers, then do a web search?
