Next, we mounted the JP3 Motorsports billet RX7 13B-REW to RX8 AC Compressor Adaptor Brackets. These brackets offset the compressor to be aligned with the RX-7’s crankshaft pulley.
We bolted the RX8 compressor to the engine and there is noticeably more clearance and room around the smaller compressor.
With the new A/C compressor mounted, we turned our attention to the passenger footwell to remove the A/C evaporator.
JP3 Motorsports has an excellent tutorial on the removal process of the evaporator:
This was by far the easiest evaporator removal that I have seen from any car. It was significantly easier than even a Miata, requiring loosening of just two nuts before the entire assembly pulled out. There is zero reason not to remove the evaporator to inspect it, clean it, and replace the o-rings if the A/C system is ever discharged in an FD.
With the evaporator box removed, we disassembled it and inspected the evaporator core. We were pleasantly surprised to see how good of a condition the evaporator core was in. Due to the blocky expansion valve, our car is a LHD DENSO Evaporator.

Awesome article and JP3 makes some awesome products. I had no idea their AC kits even existed.
They are constantly innovating and making amazing products for the RX-7 platform. Check out their website and look around!
Excellent article and one I’ll look at replicating if my ac goes on the FD.
Good stuff! Can’t wait till you get it up and running!
Jp3 had excellent customer service. They’ve spent hours with me to trouble shoot.
