What about Koyo? They make an application specific aluminum radiator for the 98-05 GS300. I know it's still not the best but its affordable. Part #A2222.
would prob work..it's just an all aluminum OE replacement, whereas mishimoto is a racing replacement and much thicker.

Mishimoto is just another affordable radiator available for the consumer to purchase. Definitely would not go as far as stating it is a "racing" component but I guess it will do the job if your not making tons of horsepower.

Make a mental note the difference in weight if you can...even better, actually weigh them.

Koyo radiator? They don't make full aluminum radiators for the GS. They make OEM replacements though.

yea i got the oem replacement since my mechanic said it was one of the reliable ones out there.

but i have a question...will it still cool down my tranny fluid like the oem toyota one? or should i also get a tranny cooler also.

ok so i installed my oe replacement koyo radiator and it is a perfect fitment. the quality of the plastic on top and bottom of the radiator of the koyo doesnt seem as hard as the toyota one. they weight almost identical maybe off by a few ounces. i did have a problem with the drain plug..its leaking by drips. have to call them to see what they can do.

Manual transmissions do not have the 2 lines that help cool down the transmission. Going from Auto to manual is fine, but manual to auto is not if i am correct.

I would imagine a generic radiator from Jegs or some other performance parts supplier would work with a little modification. I took a measurement of the stock radiator quickly and it was around 30"L x 19"H.

Here's one for $140 measures 28"L x 19"H.

http://www.jegs.com/i/JEGS-Performan...52008/10002/-1

Better size 31" x 19", core size of 25.625" x 17.5", cost $150.

http://www.jegs.com/i/JEGS-Performan...52009/10002/-1

Edit: I'm actually looking at using the LT1 radiator out of a 1993-1996 Camaro, as it's the same size as an LS1 radiator, but almost twice as thick at 1-3/8" thick for my LS swap.

Hello,

I know this is a old thread but I didn't see anyone mention what supra radiator to use, does it matter or are you guys fabbing up a JAZ70 or JAZ80? I am building a 2jz with an R154 and I just wanted to know which rad you guys were refering to.

Thanks
