Any relay should work. If you look at the circuit digram for the ae92 4agze (available from club 4ag), you'll notice the S/C clutch together with a few other electricals on the engine runs off the EFI circuit (B-R wire) which has only a 15A fuse. The fuse will blow long before you burn out a decent quality relay, that is if the person that wired your car did it properly.
Check your wiring. Search google to find out how an automotive relay works.
