Hey all , I have an rx3 with a 13b bridge port and I'm looking for a high quality radiator . E bay has a bunch that all look the same , I want better cooling and no epoxy in the construction of the radiator . Any good info would be helpful

 

The after market aluminium gen 1 RX7 radiators work well in an rx3 you can find them on ebay

 

I run an all aluminum rx3 rad bought of ebay ,works great and was only 130 shipped.Stock 12a and it runs cool enough you don't need the e fan on except on idle. Needless to say i was pleasantly surprised with the quality.

 

You can always get a large universal aluminium radiator and modify it to fit. Welding on some brackets isn't too bad if you have access to or know someone who has a TIG welder.

 

How did you install the 13-B? Notched front engine bracket or engine/trans pushed back. Im asking coz it makes a difference on which radiator/e-fan to use.

 

13b is stock for cosmo's

 

My experience with eBay radiators was not good. The one I received wasn't even flat. Guy wouldn't respond to my requests to return it, ended up filing a chargeback to get my money back.

PWR Australia makes a brilliant multi-pass crossflow design but it requires you to do a bit of cutting and drilling of the side flanges to get it to fit.
