What's a good, lower cost radiator for a MK III?

I Don't need an oil cooler also do I, I could have sworn the 7MGTE oil cooler is mounted up with the intercooler... I could be completely wrong, but I thought the only other seperate parts I needed were tranny cooler and hoses for connecting it.

My system isn't stock; That's why I have a different oil cooler.

No, you don't need to replace the stock cooler... although I recommend it down the road if you're upgrading. The stock oil cooler system is very poorly designed; It's a pressure based system and not temperature... bad idea.

Yeah, I don't plan on doing anything to this one as far as power upgrades, if anything I will just put 3" exhaust on it. I still may however upgrade the oil cooler for those... long trips supra's hate so much

How many BTU's is the stock tranny cooler? Is pretty much any of the B&M ones better? They are all pretty reasonably priced from the site you listed.

I heard back.

I sent him another message as I've still got a question about temperature regulation (on units without an included fan); I'll post more when I hear back.

Thanks Cre, I ordered the radiator and oil cooler, still waiting to decide on the tranny cooler, whether the 70 dollar no fan one or a 120 dollar fan cooler, I believe the two im looking at are 175 degree activated. I believe thats around the temp. im looking for, correct me if im wrong.

Also, the radiator I ordered a friend recommended me, its the Mishimoto Aluminum Radiator for direct fit with the 7M. If anyone heard anything good or bad about this radiator id be interested, as I didn't find any reviews that were done by people that know what they are talking about.

I don't think it's really worth it to replace the oil cooler unless you go the distance and replace the stock pressure based system with a thermostatic one.

As for the transmission cooler, I thought it was 180? but I don't know a whole lot about automatic transmissions. Anyway, the bit I was still waiting to hear back about was if the oil cooler needed a thermostatic bypass (or if it SHOULD have one added) or if the transmission has an internal bypass.
