S13 and S14 Evaporators Interchangable - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So here's the story,

Originally I had an S14 with an S14 SR. I got the AC bracket for it and everything was great until I crashed the car. Now I have an S13 with the old S14 engine and S14 KA compressor on it swapped over. Problem with that is that the S14 AC lines don't thread into the evaporator at the firewall.

I want to avoid having to source an entirely new S13 system AND a new compressor bracket when I have a perfectly good S14 system sitting in the shop.

So with that being said, will an S14 evaporator fit in place of the S13 one? Maybe with minor modifications?

Let me know what you guys think.

Maybe try to find a fitting adapter that would join the different thread sizes at the firewall? Best of luck to you

Yeah that's what I'll try to do. Also, does anyone know the thread size/pitch of the S13 and S14 evaporator fittings?
