BTW, DEFINATELY check out the rest of the cooling system before you bother upgrading something else.

i run my car hard and even when i am spraying on the track, my temp never budges. I was amazed, once the car warms up to its normal temp, which is well under half way mark on the temp gauge, it stays there. Id check my cooling system if i were you cause there is something wrong

If you coolant is getting hot, the cooling system would be the logical place to start, not the oil cooler...
Don't waste any time or money on a second oil cooler when the original one has no problem on 300+hp engines. If you can't maintain full load without overheating then you have a problem somewhere, amd it's much nore likely to be the cooling system that the oil system.
It's unlikely you're near the limit of the stock radiator, so again don't waste money on things you don't need. Make sure there's nothing clogging the radiator's airflow, and make sure both the upper and lower plastic shrouds are in place. The dual-belt (but not underdriven) alternator pulley is a good idea in case the water pump pulley is slipping at high rpm. Replace the thermostat with a Mazda one (no other), and if you're still having problems, consider pulling and inspecting the water pump, as corroded fins don't pump very well.

In your oppinions what is the stock radiator's "limit" I plan on going with a streetported engine late this year early next. Would it be better if I buy an upgrade or will a stock one handle the 200HP I plan on putting down.
