Wouldn't a bigger Rad fix some of the overheating issues? Does the car use a electric fan setup or mechanical fan? I know that when I have electrics on my supra it would easily overheat, but using the stock mechanical fan keeps it super cold. See the problem is electric fans usually just do not flow enough CFM where as the clutch fan especially with thicker oil will float stupid amounts of air making up for tight tracks where not a hell of a lot of air flow gets over the rad.

You really couldn't have spent 10k on coolant stuff... For that I would have expected a PWR rad, push and pull fans, (if electric) and a bunch of other crap... On my mk4 supra, I used to overheat the oil after 5-6 hard laps because I wasn't getting enough air over my B&M oil cooler I installed. I needed to make a better air duct for it.

Thanks for the constructive replies.

BTW peter, you are an AUTO, and aren't auto's usually coolant cooled by the rad as well? Wouldn't a manual not suffer from this nearly as much? Doesn't that attribute even more to your problem, also you are 335 which is a little heavier which works the engine harder and longer? Are all the cars on your list 335's or are there any 135's?
