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.

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.
