Well I solved the mystery of my coolant smell and my rapid coolant loss. Turns out I have a hole in my radiator and rather than getting my now 17 year old one repaired I have decided to just outright buy a new one.

Now I have been doing a bit of looking and I like the Koyo at the moment but the price isn't terribly exciting. $350 after tax and/or shipping hurts my wallet just thinking about it.

What are some other good radiators that will support the cooling needs of a lightly modded (~250whp) car?

 

As far as Im concerned go Koyo thats what I did. The only other choice is Fluidyne which is $500 and up or you can go oem for around $150

 

Koyo, Fluidyne, MazdaComp, Corksport, PWR, Ron Davis.
Those are the ones that are out there, and a few more. All are pricey, but the Koyo is the most popular.
Try absoluteradiator.com for good prices.
They also carry an inexpensive brass radiator, that is a decent non-performance replacement and has a good warranty.

Koyo, and check www.titanmotorsports.com for their price. When I bought mine it was around $325 with shipping.

 

Here is another site that sells Koyo rads for $278.00.. www.hopupracing.com/koyoradiators.html Good Luck with your search.. Have a Good Week, Jimmy

 

i'd go with a fluidyne pwr or ron davis people on here said that the koyo is an improvement from stock but they aint that much better compaired to some of the other brand radiators
