I just got my rebuilt engine back and my stock Radiator is so bad that it is going through a full resivor tank a day. I need to know which radiator is better for street racing with Toda b's and ~12:1 compression.
I'm leaning towards FLUIDYNE but radiators.com only sells KOYO which is more expensive and it may be better.
Bonus: I'd like to be able to keep the stock fans, and I'm NOT running AC.

you cracked the stock radiator?

I haven't replaced a DC2 radiator with a Fluidyne or a Koyo but for RX7's I like the Koyo more.. not that this helps you. IMO either will be fine, was just curious how you cracked the stock unit.

 

stock unit is more than fine

 

Yes its cracked, the GSR radiators suck ***, many of our radiators go bad at the seals....

 

I like Koyo. But both are nice.

 

Yup, everyone has the same problem. I have a fluidyne but either is a good replacement. The fluidyne needs a thinner fan for the AC which runs about 70$. Not sure about the Koyo but pretty sure they require also require a thinner AC condenser fan.

 

Well I have a CTR crank pully so I don't have to worry about the AC fans, I'm just wondering which I should go with: the Koyo is $340, 53mm thick and the Fluidyne is $320, 38mm thick. I think I'd be fine with either one I'm just wondering if someone here has some hand on experience with either one which would put one over the other.

I have seen both and the koyo is higher quality.

 

You should be fine with either. Anyone use C&R radiators?? They look nice too..

 

Just ordered the Acura Integra Koyo All Aluminum Racing Radiator, for $340 + $20 for next day delivery. I'll tell you guys how it goes.
Edit: ordered from http://www.radiator.com

I have the Koyo in my EK. Very nice.

 

Does anyone know if a Fluidyne or Koyo is a weight savings compared to stock? Or, does it possibly ADD weight because of higher fluid capacity?

 

 

anyone know anything about C&R. they have a best buy for $380 shipped with cap and fans. i need a new rad also for my new motor.

thanx.

 

C&R actually has a thicker core then the Fluidyne... it is top notch...
for the price, you cant get better and beat the performance...

 

We use C&R for all of our project cars, Great quality, good fitment, no problems

hey thanx for the replies guys.

 

I run a KOYO. It's 55 mm thick, 5 mm thicker than a Fluidyne. Not sure against a C&R though. As for quality, the KOYO is nicer than the Fluidyne side by side comparo. Stock fan will work with the Fluidyne, NOT the KOYO though.

Thanks,
Victor

 

How much street racing do you that you need a better radiator? If you went to the track then I would understand.

 

 

Yup, Groupbuycenter.com is having a groupbuy on C&R radiators for $380 shipped.

It includes the drain plug, cap, AND thin fan. Ill be ordering mine soon.

 

DUH! But it doesn't look kool..

 

The GSR radiators have a tendency to go bad at the seals, in my case it is so bad it leaks an entire resivor/overflow coolant tank a day.

Also Someone mentioned on this thread that you can't use the stock fans w/ the Koyo radiator, Why can't you? Because you don't have enough room? Well I'm not running A/C and I asked the guy at http://www.radiator.com if stock fans worked and he said Yes. I'm confused now, why won't they work?
