Finished this last night, and I ended up around the same weight for r134a. I had put too much in it at first and had to drain some back out, but once I got the pressure to about 175 psi high / 55 psi low @ 95F the car was blowing cold and engaging the blower + compressor correctly. 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!
What temps are you seeing coming out of the HVAC vents with the AC running?

48.6F
It went as low as 42F on the highway in 102F Texas heat. At start, idling in my garage it was mid 60s but once I drove for 10m it held ~52 while parked.
Sorry for the late post bump, do you have brackets for us people who bought fds, gutted by other people ?
Mine is not running power steering or a/c and I want a/c fabbed back.
.I don't have an a/c & power steering bracket to bolt up your adapter to. Do you sell a adapter for this to mount directly to the block ?

Hi - best bet is to obtain the OEM bracket. We currently dont have an aftermarket replacement of this part.
One thing I haven't seen discussed is, how much PAG oil is everyone adding to the system when you buy all new components, and where are you adding it? The compressor come pre-filled, and the Google machine tells me for an RX-8 system I need: 1 oz in the condenser; 1.5 oz in the evaporator; 1 oz in the accumulator; 1 oz in the hoses; for a total of 10 oz in the system.
Is this correct?
S
Do I just poor that amount into each component?
For the lines, so I just poor a bit in each and swish it around?
