Like your sig says, "all stock" - a stock radiator will do the job, well. The 80 being one of the best built rigs and overbuilt in many areas for that matter. The '94's cooling system is not one of them, though. Just beware, mods that add weight, like armor or more stress to the drive train, such as larger tires and you'll need to upgrade the cooling system. Going to an aluminum radiator from the stock copper/brass ('93 & '94) is one of the best things you can do. Aluminum kicks copper/brass's butt when it comes to heat transfer.My 94 ran the original factory radiator day in and day out, and it lasted 26 years before it was replaced all thanks to good maintenance
When it came time to buy it's replacement i though why try and reinvent the wheel, so i went with a brand new factory Toyota radiator
I live in Arizona where the day time temps this summer have been over 110 degrees, my Factory Toyota radiator sees temps of 190 degrees with the AC on
