Welp summer is coming up and I'd like to help my engine keep its cool a little more efficiently up at the dragon this season. SO, which would help the engine out more on hot days. 1. Radiator (53/4mm Koyo probably) OR 2. an oil cooler of some sort. I'll probably do a low-temp thermostat and a higher pressure radiator cap either way. just looking for educated oppinions here...I know theres no definitive answer as I couldnt really find one after searching.

edit: took out the suspension related question. forgot to put it in the proper forum >.<

thanks for any replies of the non-firey variety, I have my flame retardant suit on

 

Use some Purple Ice this will drop the temp in your Z car approx 15 -20 degrees, costs about $10.00 a bottle, this is 1 application. If you want you can always find ways to spend more money to do the same thing, so if your mind is set on a new radaitor....

 

I would say the koyo radiator.

I was getting the engine hot at the track, so I first installed a stillen oil cooler kit. I was still getting high temps, so I then installed a Koyo 54mm radiator and I haven't seen a hot temp yet. We'll see how it does in the summer.

I can't imagine overheating my car on the street though, even driving fast. Absolute first thing to do, before any mods, is make sure you have no air at all in your cooling system.

 

I got a ques. With say that radiator keeping your car cool in the summer. Would you then want to take it out in the winter so it dsn't stay too cold??

 

my broke college-student *** is never out to blow cash on crap if I dont need it lol. will a low temp thermostat and higher pressure radiator cap help much, making the coolant cycle more often?

 

I went with a Koyo 53mm rad and APS finned oil pan cooler.
If you're driving hard at the Dragon, you might also wanna consider a power steering cooler upgrade. The stock one is pretty much inadequate.

 

I considered that one when I moved to 265's up front but it said it was primarily for cars with raised rev limiters?
