Radiator

[Bluewinters21]

I’ve been pouring over the many post at one of the other Miata forums and have found no clear answers as to which radiator to get… A lot of people seem to like Koyo. There is much debate over the 37mm or 55mm option. I also read about sealing the fan shrouds to the radiator and serious corrosion issues resulting from bad a ground in conjunction to running an all aluminum radiator… I am curious as to what people on this forum use with their FFS kits and what their experiences are?

Koyo..... 37mm is all you will need for the 1.6L. Take the fans off the stock radiator and mount them to the Koyo. Seal the fans to the radiator as best as you can.
