After my upgrade 7 years ago i kept r-12. Blows ice cold with no leaks and i use it a lot here. I havent added any additional freon since.
Upgraded AC for our coupes?
- Thread starter Dan Mooney
- Start date
R12 is the way to go.

we are lucky .. in Belgium we don't need the AC... only the heater

yeah, yeah ... but in the southern US, where we need to have AC, we get to drive our coupes for the full year (OK in ATL this year there have 2 weeks that there was snow / ice on the ground). its just nice to drive them in the winter where all of the other coupes are in cold storage.

Scott, we have days to hot also... but those rare ones we drive convertibles, not tin tops ! ... as our Morgan . 
on really hot days, i drive my 911 with seat ventilation. (seats with their own AC system) really keeps the back from sweating. you can use that system with the sunroof open and the windows down.
With global warming, EVERYONE will eventually need AC!
Ah yes, but if the global climate changes as it has historically done (and as scientists have documented it for nearly a million years), the next ice age will come not too long after the global warming phase we are being threatened with is experienced. If it is like the last ice age, all of Canada, northern 1/3 of USA, and much of northern Europe will be covered with ice/snow glaciers year round ranging from a few yards thick up to a mile or so thick. Most Coupes will get a long sleep during that era!! - HA.
Look at the chart below, which was compiled by National Oceanic and Atmospheric Administration at Boulder CO and published in 2006. We are currently at the far right side of this chart. History goes to the left. We are still about 3 degrees C cooler on average than previous 'high temperature periods'. And since it's been nearly 20K years since the last ice age, it might not be long before our future descendants will see the temp start dropping again. Significant volcanic activity can accentuate the cooling effects, of course.
There are something like at least 80 'laws of physics', 'gravitational', and 'wobble' aspects of the orbits of earth, and other planets that impact to our relationship to the sun and effect the amount of heat that arrives on our little blue orb. They seem to be on about a 20K year cycle!

I talked to Dan about the 3D parts in a PM. For those interested in an AC conversion, I suggest that you consider the 3D parts last. The thing is, I can’t run out of inventory and the timeline is very predictable. That means you can try to find a package deal for the AC setup and switch to the 3D parts if nothing shows up.
I’m working on sourcing a few evaporator boxes. The console side cores can be found with relative ease. Expect to recover them. Really the only tricky part is the evap box and a good faceplate. The side vents can be found but they tend to be cracked. Unlike the printed face plate, the 3D side vents don’t offer substantial savings over good used ones. They just rarely come up for sale. Lastly, the side vents don’t have the texture modeled into them. They don’t look quite original to the trained eye. That isn’t a problem for the face plate because it was painted but the side vents have somewhat of a leather texture from the factory.

I've done the heater core shut off valve, Sanden compressor, bigger condensor and spal pusher fan (with relays to run when the car gets warm). I also kept R12 as I believe it works better. I have not yet done the window tint, but plan to add a very light tint on my side windows to cut UV. Humidity in the DC area makes A/C a must for a chunk of the summer.
I certainly will, Peter.Dan when you get around to doing it please let me know, I want to do it as well, just got the engine in
Cheers!

Exciting to be putting the drivetrain back in, Peter. Congrats!Dan when you get around to doing it please let me know, I want to do it as well, just got the engine in
You will find a ton of info on the subject in the mother of all AC threads here:

RonP or ??? put VintageAir in this hot rod E9:
Granted, you don't have to have it laid out like that, but I'm sure, w/the OEM faceplate, the two dials for the small unit can replace the OEM dials.

And UNLIKE the OEM unit, you can probably get air to flow THROUGH that OEM vent/faceplate!
Is that your car Rob? Looks fantastic!

Stick with R-12, much more efficient than anything else. I have several shops around here that can use it legally, it just costs a lot more. Go with the Sanden compressor and better condenser out front from Old Air and find a big electric fan. Mine comes on when the A/C comes on, not just when the compressor engages. Actually helps when stuck in traffic. Cabin felt fine in northern Nevada on the way to Monterey in August at 75 MPH.
