Soubds like a decent price if the engine is still in good working order. However you're won't be able to use the hydrualic clutch transmission that comes with that car in your CRX becuase the CRX chassis uses a cable clutch tranny. Also that car is OBD-2 and you really don't want to convert to OBD-2 just to use that computer. Also the electonics on that engine(wiring harness, distributor, injectors) aren't compatible with your CRX either. So what it comes down to is you're paying $1600 for an engine that you're gonna have to run around and source parts for. I'm not ure I would get it because you're gonna have to sell of that hydro tranny and buy a cable tranny as well. Sounds like a headache to me.
You haven't told us what trim level your CRX is either. That'll also determine how much wiring work you'll have to do. Let us know man,
