radiator upgrade, what would you recommend?
I am running a T67 single turbo on a ported motor. I am producing allot of heat, normally around 85 so says my PFC. So i think its time i upgrade my coolant system from the stock one. I wanted to find out what most ppl with single turbos are running and what they would recommend I run.

fluidyne is the best but also most expensive.
koyo n flow is the second best and second most expensive
standard koyo aluminum is the most common and cheapest yet decent aftermarket(yet still OEM manufacturer) radiator.
all 3 of these are direct bolt ons with minor modifications, there is others that will fit but custom brackets need to be made.

We've installed tested & used ALL of these rads. - (been installing them on FD & FC RX7's over 13 yrs)
In order of preference:
1) MazdaSpeed Radiator- by far the best quality! and fits perfectly
2) Fluidyne - fits almost as well as the MazdaSpeed unit-also very well made
3) Koyo-either Koyo rad is good but fitment & overall quality is not as good as the others. Yes its cheapest- but in this case you do get what you pay for!

Most of the vmounts use the koyo I think. Truth is both the Koyo and Fluidyne are both great rads, hell even the stock one is great except for the end tanks.
It's just a matter of personal preference and experience with each one that people flog the issue over I think.

Search for an old thread by me where I discovered a fitup problem with my fluidyne that caused it to overheat. The upper hose connection tube welded to the top of the radiator on mine is too high. When you bolt down the stock air box it pinches the radiator hose. The fix was leaving the stock air box loose. AdamC has a fluidyne and his upper hose connection is clearly at a lower angle than mine so he can bolt down his stock air box without pinching the radiator hose. I don't know if mine was a unique manuf defect or if they changed their jig or welder had a bad day. I never pursued it with them. As I said the problem went away when leaving the airbox loose.

You can get a CSC all aluminum for less than $250 at radiatorworld.com. Reputable shops put CSC rads in cars as replacements all day long. My CSC radiator has kept the car frosty during autocross grid and traffic.
The only thing I didn't like was the poor quality drain o-ring so I replaced it with a tight fitting fat GM injector o-ring.

Fluidyne is only 38mm thick, both the Koyos are 53mm. I have done side by side testing and the Koyo always out performs the Fluidyne. Not to mention the quality of the Koyo welds and overall cunstruction are much better.
I have had Fluidyne welds fail, I have never had a Koyo weld fail.
I see absolutely no benefit to Fluidyne.
1. It cost a lot more than Koyo
2. Quality is not up to that of the Koyo
3. The petcock drain system lasts about two times before needing replacement
4. Considerably thinner than Koyo
5. Integrated mounting brackets look cheap when stood up for FMIC

What's the fitment of the koyo radiator in the stock location? I have a Greddy SMIC and I wonder if the thickness of it will cause problems with the intercooler.

I'm pilfering the following from an ancient thread I started:
Bump for a good thread, and I compiled some info about core thicknesses as well:
1.000" core: OEM Mazda 93-98 Radiator
1.100" core: OEM Mazda 99-02 Radiator
1.125" : Mazdaspeed Radiator (AWR / Ron Davis)
1.250" : CSF aluminum one-row
1.500" : Fluidyne (probably one row, due to thickness?)
2.047" : Koyo Racing (two row?)
2.062" : CSF two-row
Personally, I'm planning to buy this one-row CSF, because of the price and fitment.

I ordered the "medium" unit from RadiatorWorld, and they eMailed me 4 days later to tell me they couldn't get it anymore. I'm glad they did 'cause I found the same thing on eBay for $160 shipped.
My only complaint about it is that the upper mounting ear tab things aren't very sturdy, and I had to trim some metal off the outsides of 'em to get it to slip down between the frame rails.

I will say that a fluidyne does its job just fine for a street car. It keeps my car hovering around 80-85C on days less than 80F. But then again so does the stocker.
