I highly suggest an oil cooler on a turbo car. You know you can run the evo3 filter housing on the 2g for external oil cooler? If you want to run the stock water cooler unit no problem, just use my write up to save you headaches(either way water running to it or not it can loosen up). My oil temps while sitting still easily got to 240degrees before I started moving so expect to see that as a minimum temp with out cooling. So to keep oil from breaking down use a good synthetic oil and change at max of 2k without cooler.
