i was wondering wat type of radiatior you guys are using?

 

Stock.

Alot of people use Koyo or Fluidyne.

 

Fluidyne. I like it. Direct bolt in, no fab needed. But there are larger rads out there, for less money. If you are into fabrication, then Summit Racing sells some HUGE rads that can be made to fit.

 

koyo the install was very easy and it is hard to beat $300

 

on the koyo wat pressure cap are you using? i got a koyo and i need to find out wat cap to use. thanks

 

radiator cap? stock i would think. i dont have my stock one, but i'm sure it fits. i was running an old miata one (0.9bar), but i replaced it with a greddy 1.3 just to be safe.
i have a Koyo, btw.

got a Koyo sitting in my room... waiting on the new hoses and belts to arrive.

 

gmc aftermarket ebay one.

 

i bought a koyo and a flexalite electric fan and it looks really sweet in the bay and it fits but had to do some minor custom work to it.

 

i imagine all the custom work was for the fan since the Koyo is a simple install requiring no modifications. just letting the original poster know. when i read it, i first thought you meant custom work for the radiator.

haha, you are the original poster. well for anyone else who reads this.

me too. looks better. the Koyo for the S5 has the long neck, i believe. if so, yes, i have the S4 one.

 

I have a S4 Koyo on my S5. I love that thing.
