Hey guys,
I'm having to get a new radiator and I'm looking at koyo radiators. I'm not sure whether or not to get the dual pass or long filler nflow. Also would I need to buy any additional parts for installation or is it a direct bolt in.

This is the one I'm looking at: R1144 Koyo Aluminum Racing Radiator 89 92 Mazda RX 7 | eBay

If y'all have other suggestions let me know.

 

That pic is deceptive as it show the hose positions in a different spot than the original FC rad.
Now you can run either rad but I think the drawback is the stock shroud.

I used a triple pass in a S4 FC but it was on a S5 TII engine..Worked great.
(had a Merc Villager Efan on it)
By the way KEEP your Rad MOUNTS off the stock rad..you have to use then to put that Koyo onto the car!

 

The radiator is a bolt on but like misterstyx69 said, you need to transfer your stock radiator's mounts over to the Koyo. You won't need any other parts but it's a good idea to change your radiator hoses if you've never replaced them.
