on my 400, I used the supra mkiv radiator w/ mishimoto supra e fans. Easy to wire up. You have to reweld one bracket for the fan and build custom mount for the bottom of the radiator. You also need a new overflow can. Nothing too fancy

Thanks Speedaddic.

So what about the automatic transmission cooler? does it provide that on the same radiator?

I used the fluidyne radiator for a 94 supra. It fits well! does it's job.

All you guys are on 5 speed? Is there a connection for the automatic tranny fluid on those all aluminum radiator? Doesn't look like any of them provides cooling for auto tranny. So someone must have another cooler for the tranny with an electric fan, otherwise, the tranny will run hot.

I currently have an external tranny cooler but it's not fan activated. It runs in sequence after the stock tranny cooler. Looks like there are some sales on temp activated electric cooler.

I might do this... but a little different. I will cut into the metal piece and push the radiator forward to provide more room for future upgrade

My car is still automatic. I have a 2 trans coolers. One is the stack type and the second is a rail type under the car. I only know of one guy that has a G4 that has a 5 speed....TTurbopimp

umm hmm, its actually a 6spd!

I dont have one of those trick *** radiators though. I might have to go find a used one on supraforums.

I've got a large aftermarket tranny cooler. The one hooked up to the radiator is good for getting the tranny to operating temp, but not as well to keep it cool because the radiator fluid gets so hot.

hi98gs, the fans mounted on the other side of the radiator?

HI98GS

Yeah unfortunately I have to use pusher fans (zirgo 16" x 2), which are not as efficient as a puller fan to help cool the radiator. But what ya gonna do when I can't relocate the twin snails without doing major reworking.

Thats dope speedaddic!! I just order my Blackworks radiator with mishimoto fans and shrouds

I forgot to mention, you may have to bend the brackets a bit to make them fit. Also DON'T FORGET YOUR TRANNY COOLER!!

Oh yea, I also cut my existing upper radiator hose to make it work. I am doing a custom mandrel bent pipe and chrome plating it in the future.

Yeah getting a tranny cooler to. I have a r154 tranny built for 1000 hp and a 5 speed in the car
