Well this is every rad that i can find that fits a 93 RX-7. If there are better ones that arnt listed or you know of any one that makes a good custom one please let me know. Also i have a front mount so whatever i get wont be mounted in the stock mounts need a strong rad to take the abuse. Thanks for the help.

 

i like my fluidyne

 

I like my PWR it's the same size as the fluidyne and quality, but it's polished.

 

well any one of those rads are going to be better than the stock rad, which everyone knows.

i would say it comes down to your personal preference, which one do you like more.



fluidyne and koyo seem to be the most popular, although you'll be fine with whatever one you choose

 

Not FD related, but I run a fluidyne in my supercharged mustang. Brought my underhood temps (subjective) and water temps way down despite the really bad overheating I used to suffer. Note that the fluidyne in the mustang is a 3-core but still fits in the stock location. I don't have much experience with the FD fluidynes but I plan on going with a fluidyne once I get time to address the radiator (currently stock).

 

koyo dropped my temps like a rock and was cheap.

 

I prefer Koyo- good quality, fit and drops my temps nice.

 

M2 all the way. It's almost twice as thick as the fluidyne or koyo.

 

koyo

 

I dont have one cause my car came with an aluminum rad. But if I had to buy one it would be Koyo. From what I understand it requires the least amount of work to get it in their. Does what it is supposed to do effectivly. And most of all.....Its cheap!
