I will say, we googled the RX8 r134a pressure specs, and oddly it was listed around 15-20 PSI for the low side from this forum post, which is contrary to every other pressure chart I've ever seen which has Low around 50-55 for 95F ¯\_(ツ)_/¯

Overall this was a pretty fun experience doing the install. The videos from @JP3 Motorsports were of great help, and all of the parts fit like a glove. It took about 8 hours total across 3 sittings, but we were very meticulous and had consistent beer breaks.



Box of stuff. All neatly packaged and labelled.



Cleaned the evaporator and swapped the expansion valve. Video was great for this, I had never encountered the "cork tape" before.



Taking everything out.



bigger isn't always better



This was a very tight fit. I would recommend getting the ac lines attached before fully bolting up the compressor.



Easiest part of the whole job, the condenser bracket fit perfect to the Greddy V-mount rig.



held vacuum overnight with no issues!
