However, your better to find and cure the problem rather than just randomly change or add things.
First make sure the cooling system is functioning as toyota intended it to. Once you're sure of that, it could be as simple as more power = more heat, the same thing Tapage experiences.
In which case turning down the fuel will help.
But turning down the fuel will eventually solve any heating problem. Go low enough on the fuel and it wouldn't even need a coolant system.

Huh! I was under the impression that with a smaller turbo spinning faster there would be more heat? I mean you said yourself that if it was operating outside its best efficiency it would cause additional heat. Wouldn't a turbo that is too small be operating outside its best efficiency?
I guess my biggest frustration is my inability to find the gauges to properly even monitor what's going on... for all I know my EGT's are totally fine and it's only a coolant temperature issue I'm encountering!! I doubt that though unfortunately. I have a bit of high temp material I can use to insulate the exhaust tube where it goes closest to the intake... I'll see what happens with that at least. As far as an intercooler goes... well if that didn't solve the problem I'd still end up with an intercooler!
