you dont need an oil cooler if you run a good synthetic oil like amsoil as long as you dont go above 320 degrees F, the only thing is you need to raise the limp mode protection in the ecu to 320 also i dont know if it is tuneable, 320 is where you get the warning light to slow down for corvettes and and you need to get your oil above 212 every time you driv to evapporate water and contamination
if you are between 212 and 320 every time you drive you are ok and dont need anything, if you want buffer be between 225 and 300
