AC WORK

If you have not followed my journal, I bought my car with a crashed front, and I never intended to put the AC back on so I skipped this for a while, but last time I was really dying at the track waiting on the grid. At the time I also did not have side windows .... While driving the NACA duct worked really well, but the grid was torture, and now that I have my electric windows back in the car. I decided to put the AC back on

I found out that the knee bar allowed for the AC unit to get back on so I was curious to see if I could get some cooling back in the car.

I already had most parts laying around in storage, but I had to buy a couple more parts like used compressor and new AC condenser/'radiator'. I found, on eBay, a cheap used compressor ($200) and a cheap brand new ($99) AC radiator.

To keep cost low I decided charge the AC system myself. I found all parts at my local advanced auto parts: AC gauges ($50), R134a gas can ($50), Gas can to AC gauge adapter ($15). I bought the vacuum pump from harbor freight ($20).

If you are like me with zero experience in HVAC, I found a great video detailing exactly what to do:

The brake ducts are squeezing in very tightly, now I understand why the TMG german team created some different brake ducts. If you keep your windshield washer and AC, there is no way you can fit the brake ducts.

For info, my system was completely and by adding 395g (full can) of gas 134a, I was up and running cold as ice.
If you need to trouble shoot the HVAC gauges, Follow the instruction in the BRZ workshop manual they have all sorts of scenarios in there to help you figure out where the problem could be. Lucky for me it worked right away. My low pressure was reading just as the manual says, between 20 to 31 psi.

Now I need to create a top box for the interior radiator, to avoid creating too much condensation behind the dash, but at low speed I think I'll be allright in the meantime.

I "only' have to follow the template of the top box (white thingy on the top left side) and make 2 outlets for brake duct there and I should be golden
