by reading here, it seems that the only different bit is the condenser fans, I know my car is R134a, has twin fans at the front and I get numbed fingers from the cold - so much that I have to dial it down to 78F to be comfy.

As our condensers arent worth it, I believe it would be mighty beneficial to use a multipass condenser or even a refrigerated dryer (seen that in porsche once)
