What do you use your car for? Street driving only? Road racing?

RadiatorWorld.com has a selection of 3 radiators - stock OE replacement (copper-brass, limited lifetime warrantee) which fits almost perfectly except for a slight, easily-corrected, bottom tank interference with the LH lower rad mount ear. They also have 2 types of aluminum high performance radiators available.

For preventive maintenance, I just installed the stock-replacement copper-brass one, and it seems to be quite well made, and looks like it has more cooling capacity than the OE one.

I have the radiatorworld.com aluminum race radiator and its huge. They have really good prices as well.

 

You can't go wrong with a Fluidyne. I've never heard of a single problem with one over the last 8 years.

 

I'll add my 2 cents worth in support of the radiatorworld.com stock replacement radiator. All metal construction, PERFECT fit, increased capacity over stock, and all for $167!

 

fluidyne or koyo

 

thanks for the help. i got a lot of usefull info now

 

Ron Davis rad..... hey.. it its good enough for Mazdaspeed, its good enough for u :]

 

I went the Radiatorworld route as well without knowing it. Huge frickin' radiator that came out to be cheaper than both Koyo and Fluidyne.

 

Pwr!

 

I like my Koyo but it wasnt a drop-in replacement. I got a friend who sells them for $290 shipped.

 

I have that radiator as well (the biggest one).. at my last track day highest temps I saw was 190* F.

 

PWR!!!
australian like steve irwin

i got a fluidyne and it works great.. and not alot alot of modding for that one
