Upgraded rad for `85 GS 5 spd??
I just found out that half of my radiator is missing. Seriously. I took my shroud off and about the bottom 4" of the radiator is missing it's fins completely. Tubes are still intact, and they don't seem to be leaking, but I'm sure it won't be long. Just touching the other fins makes them crumble. So, I'm looking for a new rad. Is there any easy upgrades for the stock radiator? One from a later model maybe? Figure if I'm gonna replace it, might as well go with something a little better. Or should I just stick with stock? Motor is just stock with some bolt on mods coming. Thanks

I think just having a new stock radiator is an upgrade for these cars by now......
I got a Modine replacement for my 7. If I remember right it was $120 but shop around.

If you're running at stock HP levels the stock rad is more than sufficient. If you're serious about increasing the cooling of your motor, you should look into removing the beehive oil cooler under your oil filer and installing an air to oil cooler from a GSL-SE, 2nd Gen RX-7 or 79-82 RX-7. Those beehive coolers are really marginal and can contribute to dowel pin leaks, among other things.
