used 134a compressor in a r12 system

Year: 1992
Make: Acura
Model: Integra
Engine Size: 1.8
Refrigerant Type: R12
Country of Origin: United States

Hi, names Brian, I'm new to the site. A friend of mine told me about this forum after seeing me go crazy
trying to get an answer to what I thought would be a quick question. I drive a 92 Integra LS, which I'm
getting ready to do a JDM motor swap out of a 96 LS. My car uses R12 and the 96 uses 134a.
My question is "can I use the 134a compressor from the 96 LS in my R12 system, or should I convert
the system over to 134a because I changed the compressor?"

ANY advice would greatly appreciated.

Better idea is to drain the oil from the 96 compressor and refill with mineral oil and use R12. I would also replace the drier and the oil related with that item.


When considering your next auto A/C purchase, please consider the site that supports you:

Do you even need to change the compressor? Your 92 compressor might bolt onto the new engine. Also it's usually possible to R&R engine without disconnecting any A/C lines. If you have a working R-12 system now, try to leave it alone if possible.

Sorry, I should have mentioned that mechanically it still works, it just has several leaks.
Instead of having it rebuilt or buying a new one. I thought I would use the one that came
on the motor. Having between 20-35k it would be worth a shot.
