C&R and Koyo are the only 2 IIRC.

Wedge · 06-09-2004, 09:16 PM

And FYI on the Koyo, the stock fans will not bolton and expect to them to fit.......to thick, you need flex-a-lite fans. Just finished doing this.

Unsung Boxer · 06-09-2004, 09:46 PM

you could always put an L one in. Ive never understood these radiator upgrades... what is the benefit? Isn't money better spent somewhere else?

I am running 12 psi on an EJ22na/t block and my temperature is perfecly find w/ stock radiator.

Extensive track usage.

Unsung Boxer · 06-09-2004, 10:48 PM

does a stock radiator really not hold up to track usage? I mean, how long is a coarse? And more importantly, how many people do endurance races? Ive beat the hell out of my car for about 15 minutes at a time, and Coolant temperature never really gets that high, plus im only using an L radiator.

Anywhoo, im not debating that an aluminum one is better, but it just seems to me that money can be better spent elsewhere.

But, you're in WA, I'm in South Fl.

Unsung Boxer · 06-10-2004, 10:41 AM

thats probably true, i dont think i even need a radiator up here... i could just let it air cool.

Summer in Phoenix, AZ... temps are regularly over 100*, long spans of days 110*+. Over 100* starting in May and runs till Octobert...

I've been out here when it was 124* out.

That's why I upgraded my radiator. I would agree that if you lived somewhere cooler, like Alaska for instance, money better spent elsewhere (like a battery warmer...

)

do you guys notice a huge difference?

Not unless you have a different thermostat (I believe the STi ones open sooner), which I've been trying to source with no luck.

Have any of you guys heard this?

the JDM sti (GC8) and Sard (I've read)...two more options...my L stock radiator doesn't get the job done...I'm buying a radiator...

Wedge · 06-11-2004, 02:03 PM

Found out a company called Crucial makes a cooler thermostat for our cars.

The Koyo radiator is no joke, that thing is huge! The only way to run it and keep your A/C and power steering is to use some very thin fans, as Wedge said. It is a nice piece, though, I'll have one eventually.

Wedge · 06-11-2004, 02:38 PM

Yes! Check out some pics Nino took of his setup:

HOK · 06-11-2004, 08:16 PM

HAHAHAH theres not way that will fit in my car with IC tubing... I guess i;ll count on the -20 weather...

no-coast-punk · 06-12-2004, 11:53 PM

I've ran my car pretty darn hard with my stock RS radiator on 100+ degree days here in CO without too much of an issue. A cooler thermostat won't really help keep your car cool if you are beating on it, the coolant flow rates and amount of coolant exposed to air is what determines how many BTU's can be sucked out of the motor, not what temp. the thermostat opens up. All a lower temp. thermostat will do is kill your gas mileage around town because the ECU will think the car never hits operating temp and will run richer.

subiekid · 06-13-2004, 01:58 AM

Can someone measure the stock rad? I have been looking into just getting a custom rad, but if I can retro fit one of these then that would be good.
