today while i was replacing my front cover i thought to take the radiator off for easier access. and while i was in the process of that i found out that my current radiator is garbage. (it looks like silly puddy was used to repair the outlet on the radiator. sooooo, im curious as to what the biggest radiator i could fit in there (with the least amount of modification) was. motor is an s4/s5 NA bridgeport.

 

use a 81 / 85 3 row rx7 radiator, you just have to use big washers on the top corners

 

I got an older Rx7 version ( that takes the oil cooler below) and I needed to fab some brackets on the drivers side, as it is a little bit narrower than the standard Rx2 radiator. Never had a problem though....

 

PWR makes some pretty nice aluminum radiators that will bolt into any/all of the old school rotary Mazda's.

I also got away with using a 1st gen RX7 radiator in my REPU (modded some brackets for one side) but think I'll be going for the shiny stuff when it comes to the RX-2.

 

Here ya go. Not sure if you'd want to be a guinea pig but what the heck!

Found a better deal and probably a more reputable seller since those Ozzy's are crazy for their old school RX's.

Hello

I been running one of those ASI radiator on my 76 RX-4 for a few months now and works great, no issues, car runs cool.

It fitted perfect, my other choice was $600.00 with many mods to make it work.

I learned about them on the Aussie rotary site, they were selling like hotcakes on their group buy!

I also seen them on ebay for $305.00 or something close to that!

I had them in 4 days after the purchase was completed!

 

thanks guy. i ordered the three row one from mazdatrix.
