Looking for a radiator setup.... Recommendations Needed!!!

[Duker]

Hello all,
I'm attempting to go KA-T here soon and I am trying to hit all aspects and cooling is up next on my agenda. I know you can't get cheap, reliable, and good performance all in one. So I'm looking for a happy median here. I've been looking into Koyo with Fal Fans, Mishimoto, and Cx Racing. Which setup is the most for your money..... Or bang for you buck per say..... I'm only looking for recommendations from people who have experience with these products. Not some chanting cheap chinese junk. I also understand that there has been posts about this before, but that was then this is now. Products change for better or worse overtime.
Thanks for any info you provide......

I'm running Koyo rad with stock fan + shroud on my KA-T.
Great setup, I like it.

[Duker]

are you saying stock electric fan or clutch fan???

[Slidin' Sam]

I have SR w/ Koyo 3 core...copper, not aluminum. I run the OEM clutch fan and fan shroud along with no thermostat. Driving temps stay below 70 C and racing stays under 90 C. Normally I am somewhere in the the 60's when normal driving and 80's when drifting.

[Duker]

hmm.....
thats pretty reasonable temps, never thought ab not running a thermostat... are there any negative effects of that??

i have the isis alum/fan shroud combo along with the nismo thermo...so far so good and i run my a/c when it's hot, but i'm running a stock motor. heather (drift_goddess) runs a mishi rad. w/a clutch fan for her ka-t setup.

Well, those are summertime temps. In the winter it will be down in the 50's, so you have to put some cardboard in front of the radiator to block air flow so that the car will heat up once you start driving it so that you will have heat. You wont be able to let the car idle for like 15mins before you leave in the morning to get the heat up inside, it will still be cold. BUT, for me, the car is strictly used for racing now so it doesn't bother me. Some people have came out and said its bad, but just like everything (especially on zilvia) there are a lot of opinions that are not based on facts. I do this, along with multiple friends, and none of us have experienced issues...other than being cold in the morning on the way to work! lol

Mishimoto is tight. Many drift events offer their "Mishimoto loves drifters" promotion which is 50% off to people that actually go to drift events. Makes it a seriously cheap and bad ass set up. I have had a Koyo for years with no problems even at 110+ heat events.

Haven't had any problems with Mishimoto for my Miata. I'd probably go with them lol.

Coming from the Mitsu X world, everyone there loves the Mishimoto radiator and fans for Auto-X and thats what my plans are for the S14

not to be a nay say'er but if you are running on the track only you should be ok but just a little warning to you if this is your DD and its as cold as people say it is you will have sludge from all hell so i slight suggestion might be get a lower temperature thermostat maybe one that opens up at 160 degrees (71 C) and you shouldnt have a problem

[Slidin' Sam]

If you stay on top of your maintenance you won't have to worry about sludge becoming a problem. Once again, you could bypass having a thermostat and make the car run warmer by just putting a small piece of cardboard in front of the radiator for daily use. When I used to daily my s14 I would do that in the winter time. Summer time you shouldn't need it.

[fliprayzin240sx]

Not running a thermostat...I'd be worried about the extra wear and tear on the engine since it takes the engine so long to get up to temp. Rings need to get up to temp to seal better, oil temp needs to get closer to 80 degrees to be efficient.

Spend the money on a dual pass radiator more than anything else. KA and RB radiators are the same, inlet and outlet are on the same side. Coolant have a tendency to stay on the same side of the radiator and go back into the engine. If you have a dual pass, coolant will have more time to sit in the radiator to cool down, instead of it just shooting down the left side core of the radiator.

[Duker]

ok then so whats a good dual pass radiator????
and it is a dd with occasional track use..

this guy who races his car and is pretty internationally known says a stock radiator is a okay. (700hp car)

[Duker]

hmm... something to consider then...

[90white240]

I have had my koyo for little over a year now, and its never been a problem. Just my 2 centavos!

I think that's a Yashio Factory copper core not a stock alum 1 row.
