I've put a bigger turbo onto my CA18, along with a bigger intercooler, blow-off valve and new piping.

The upgrades came off another 200sx which seemed to do deal with the heat well. I find my 200sx seems to get extemely hot, although the temp. gauge sits at a good level.

2 weeks ago my thermostat bombed out. I've had 5 pipes melted and my radiator hose has popped off 3 times, which split this afternoon. It's all come down to an obvious heat problem.

I've thought about this situation for a long time, but I'm not too sure on which way to go. Any advice on ways to make your car cooler? I'm planning on making a bonnet scoop and a ram pipe to bring up air through the front bumper, but thats not going to be enough.

I've seen some HKS oil-coolers. Do they make a difference? Are there any other products like oil-coolers/water-coolers that will make a big difference?

Some1 plz help!!
This is an emergency!!!!

Check out your radiator and cooling system. What pipes melted? What were they made of? If you're at a point where steel pipes are melting, while your guages tell you the water temperature is appropriate, you've got something seriously wrong with your cooling system. Adding on to an already broken system is not going to solve anything.

Yeah, you've got some definate issues that you need to take care of as far as your cooling system goes before you start buying hood scoops, etc.

I've tested the radiator and it is fine, it seems to handle the higher heat levels.

The pipes that melted were breather pipes on the engine cover (the cam covers) and the breather pipes for the turbo.

lol, I'm aware that I have some serious issues :D It's all the crap mechanics we have here in SA. They initially put the breather pipes on wrong, which caused the turbo to get hotter than usual.


Anyone know of any good heat-res performance mods apart from a racing radiator? Thanks for tha help

You could try a new thermostat and a new raidiator cap. Like NISMO or Greddy, that lets off pressure at at lower heat levels or something like that. It's early on a sunday morning and I can't word things right......also, you can try Redline Water Wetter which should cool things down a bit. Good luck!
