Re: pros and cons of fitting oil coolers
hmm...you probably need someone with deep insight to your engine to give you specific advice before you fit one.
You need oil pressure, sticking an oil cooler on your system might alter it too much. Unless it is running too hot there is no immediate benefit.
I suppose if the oil pressure can be kept up, you could drive your engine harder for longer time with oil cooler fitted. But this is theoretical, as the cooling system might be the limiting factor in any case. If the cooling system is not the limiting factor, then maybe it would be the power steering or brakes..
The TS' seems to cope very well with being thrashed as long as you keep topping up all the fluids levels to max and change the oil often. In the real world i think you might find the brakes gives up first, then the power steering, and then maybe oil or coolant.
If you raise the rev limiter it might be worth thinking about oil cooler though..
If it is running hot ATM, the obvious benefit is that it lowers the oil temp so it doesnt burn through the film. But if i had this problem, I would try using a good racing oil and fresh coolant before sticking an oil cooler on.
