Forget the other brands, stick with the Nissan. I have a turboed A14 with no intercooler and it runs at around 140-160 degrees f' I'm using a N13 alloy radiator from a pulsar. It cost me $110 from wreckers with a mark on it. I had to dint the inner guards with a little heat and a ball peen hammer. Then use a universal top hose from auto barn or Repco as the tubing out of the radiator the thermostat is alot different. It's been in the car for 4yrs. in Oct so its all good.
