I'm assuming you are using an SR20 with the JDM compressor. You will need to trace the signal wire, to the relay. On S13 SR, its pin 106 Green/Black, and it could be the same for other generations. Just check the wiring diagrams. The A/C clutch must be signaled by the ECU because it puts a lot of load on the engine, and thats why its stalling out. The engine needs prepare itself for this load by increasing the RPMs.

Edit: Also, the ECU needs to shut off the A/C compressor during WOT acceleration - for obvious reasons.
