summer is coming,I am worry if my car would over heat under boost, i want to do something about it , first of all, I was thinking to get a (Dual) oil relocation kit with a oil cooler . second, I want to upgrade my Radiator (bigger one) so I hope that would cool down some of the internal heat?.... what do yo think??? would a KA would survive the Tx heat? (it will get very hot here)

I got a intercooler already, so that would help out alot as well....what other way to cool down the internal .... NOS ? Alcohol? i was thinking either one of them , I think Alocohol is cheap but how much different between Nitrous and alcohol ,I do know there was a thread about the alochol , but for comparsion, which woudl be better more advantage to a stock internal with boost ?

8psi on 300zx T3 turbo ( planning to run 10psi)Intercoolerstock internal running 12:1 to 13:1 A/R

I don't think an oil cooler would be needed yet. If you are worried about overheating consider bigger radiator, FAL electric fans and a lower temp thermostat.

I'm not sure I understand your second question. Nitrous helps cool intake temps so does water and alcohol injection. Water and alcholol injection also help you run higher boost, it makes your pump gas act like higher octane fuel. To cool your intercooler you could go water sprayed or nitrous/CO2. I would suggest water sprayer, cheaper and easier. Hope this helps.

At 10 psi, you could run into cooling issues under extended periods of boost, particularly in hot weather. I run only 6.5 psi, and the only way I can get the temp needle to rise is to turn the A/C on and drive uphill on a very hot day. With the A/C off, my car had no problems with hot days lap after lap.

A larger radiator might help, but that depends a lot on whether or not the cooling problem is the radiator. If the radiator is able to cool down the coolant effectively, then the problem lies within the motor. Using a higher concentration of water might help as water is a better medium to transfer heat.

Front mount intercoolers usually do more harm then good when it comes to cooling. It not only blocks some airflow to the radiator, but it also heats up the air before it gets to the radiator. While this air should still be cooler than the water going into the radiator, using hotter air isn't as effective. If this becomes a problem, using a larger radiator may be a solution as it slows down the water so that there is more dwell time within the radiator where it can cool longer before it goes back to the motor.

Cooling intake air tempurature is not going to make much of a difference if any to the engine temperature. NOS would probably actually make it hotter as it will require more fuel be burned with it and thus release more energy(heat) into the block.

If you do only street driving, and your cooling system is in good working order, you should not run into issues with overheating. Having a turbo in that of itself doesn't introduce more heat. But running boost for long periods of time will.
