I have an 81 brat that I would like to put Air Conditioning into. I put an ej22 motor in it. So I will have to use the EJ compressor. I got a/c parts out of a late 70's wagon to use in my brat. I will have to use the gen 1 evaporator. My question is will the ej compressor work with gen 1 parts or should I stay with EJ parts as much as possible? Does any one have a Gen 1 A/C Diagram? I know there are 2 or 3 different setups that were use. Do I have to have the electrical wires connected to the receiver/drier for the system to work?

 

Thanks

i asked dad, he says stay with ej22 parts, they use r134a gas, non compatible with the old parts for r12 gas and ej22 compresor does much presure for old parts

The R12/ Gen 1 systems can be converted to use 134A. I have done 4 or 5 of them. However, the gen 1 systems were pathetically weak, even when new. I'd stick with the newer system parts if you can adapt them.
