probably not, the radiators are the same size and shape, if not the same radiator.

get a lower temp thermostat. that will help the engine run cooler. its a good mode for like $5

The radiators are the same to my knowledge. Even if they aren't, you won't gain any HP from changing radiators. The 160deg thermostat is a bad idea unless you're modded enough to have overheating problems. In that case the 160 stat will act as a sort of bandaid to help keep the car from heating up as fast. Cooler water temps do not make hp!!!! Your water temp should always be around 170-185 no matter what the weather or driving conditions. This will keep the engine operating where it should be. Cooling the intake charge will make power, but lowering the water temp will not (lowering the coolant temp a bunch will eventually lower the intake charge a tiny bit, but you'll mess up many other things before you see a gain in power.)

I was actually looking into doing this myself because my radiator broke. I ended up just getting an ST radiator. The difference between the two is where the hoses connect to the radiator. The outlet on the ST and GT on the bottom are on opposit sides of each other. It could work as long as you get a longer hose to connect the GT radiator up with.
