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

I would go with a B&M cooler (I've got a large one as my engine oil cooler and another for my power steering), Perma-Cool should be fine (I've never used one though)... There's Canton who makes some excellent components, but their oil coolers look to me to be just rebadged B&M coolers (I don't know that that's the case but they do look identical). As I mentioned before, you need to figure out where you're going to mount the cooler and then measure to find one that will fit; Make sure you keep in mind that you also need to be able to route the oil hoses to it.

If you're looking at a long, narrow space (like along the top or bottom of the bumper support) look for a "rail" style cooler.

With the oil lines I'd recommend replacing the stock lines completely, not just extending the them; Any barb used to extend them will most likely add a bottleneck. It's not the highest flow system though, so extending will undoubtedly be fine; It's just not my preference.

Nah this is for the daily driver and the car my girl uses most, so I want it to be done right and so it will last. I'll check the B&M ones they seem to have a large range of shapes and sizes. Think I'll go out tomorrow morning and check for places to mount it.

Will those oil coolers work for tranny fluid?

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.
