Thread: Time for a new "TRUE 2.0L RADIATOR" which one should I get?

NO. U13's have the same setup as only 12-15% were MT's, the rest AT's. This came up a long time ago and use it for PS but do not use it for oil cooler, that's a really bad idea. ATF is much thinner and you do not want you engine's life blood going through the bottom of a plastic rad. I looked into this years ago before getting a real oil cooler for my U13.

PS yes, oil, NO. The crappy plastic fittings alone are reason enough, you do not want you oil circulating through that. You also then have the oil change issue, the oil outside the motor becomes a bitch to purge properly.

Btw anyone have a B14 PS res? Sick and ****ing tired of this leaky piece of **** B13 res, I have to put a sock on it every trip to the track or autox because it leaks around the cap when you flog the car...

Ok so its fine for a ps cooler, but not an oil cooler. By the way the fittings for the cooler are brass, the inlet an outlet on the radiator is plastic as well as the end tanks of course. I have to go to the junkyard tomorrow and get a radiator to get me by until i can afford the one i want from summit.

But from what i have seen the a/t p10 g20's have the thicker nx radiator with the built in trans cooler. The m/t p10 g20's have the 1 row thin radiator. This is what i have gathered from owning a p10 and looking at a dozen or so at the boneyard.


I agree b13/p10 ps res. FTL.

Guess thats a no.....

Agreed on link #2

Since this thread I ran an entire season (10 events) including very hot summer days, 60 minute sessions on the track in 85*plus weather, driving to/from, sitting in traffic with A/C on, and the car had never, ever overheated. Even after a 30-60 minute flogging on the track temps were under 190*. Koyo took everything I could throw at it and just shrugged it off. Since then I bought a 2nd B13 with the "GTi-R" rad (guy bought it out of the NISMO catalog for $200+) and I have to say, not impressed. 33% more than half what you need...do the math.

^ well to me the koyo r radiator is the best upgrades period. others might work good, but the koyo is a big ass radiator. so its not the best on clearences issues between race headers or turbos, but it does work great and you cant beat it.

^I agree. I bought a KOYO and never looked back.

yeah its the only way to go, i wouldnt run anything else.
