I am planning on doing a 4g63 swap into either an 87 or 88 Conquest here pretty soon. My question is has anyone else ever tried to retain a/c after this swap? I plan on getting a ton of custom lines made to get everything matched up and plan to use the dsm compressor and switches and the quest's condensor and evaporator. Any help would be greatly appreciated.
BTW, I'm a noob here but not to this kind of stuff, I'm a master tech for Toyota and have been fooling with DSMs since 97.
A/C?

The A/C should only be 1 wire to worry about. I havent made the lines for something like that before but I imagine you would just have someone proficient at welding aluminum adapt the lines.

Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.

They make hoses there and can adapt almost anything. By going somewhere like that you end up with some reasonably priced AC hoses that look stock. I plan to keep the AC as well. It's awful hot here in the south.

If you plan on keeping your a/c as well I might have some good news for you. Of course I won't know until I get the car and finish the swap . . . .BUT . . . I just dug out one of my 91 Eclipse Factory Service Manual(FSM) and looked up the electrical diagram for an '88 Starquest. After analyzing at the diagrams for quite some time I have come to the conclusion that electrically this will be a pretty simple and straight-forward swap to get the a/c going after the swap. The only parts from the DSM that I will be using will be the compressor itself, the dsm wiring harness, and the dsm ecu. Of course if you did the 4g63 swap you already have the wiring harness and ecu in your car. It appears right now that the hardest part is going to be the hoses, but that won't be too bad.
