I have an 86 non turbo Rx7. Bought it in L.A and whern I tried to drive it back to Vegas it overheated on me. Since then it has overheated several times, and it putters when I accelerate. I changed on the water pump, fuel pump, clutch fan, and check the psi in a compression test. Psi reads normal, no more leakage, but I still cant drive more than 20 minutes without overheating. I know I must have a crack in the block somewhere, but I don't think its the apex cause the car still runs, and have power. I didn't pay much for the ride, and I dont want to put much money into it. As in I'm not interested in an engine swap...

Is there some sort of quick fix to give the car a little more life so I can run the track and do some drifting?

Have you replaced your thermostat? It's a $10 part, easy to do.
