Also make sure if you are buying a kit that the lines are long enough to reach, dummy fit and trace where you want to route the lines before you buy.

It makes a difference if you are tracking the car, otherwise I don't think on the street you will need it. If I don't cover the cooler in normal street driving the oil temp won't get above 80deg C and I am still using the stock water/oil heat exchanger where the oil filter normally mounts. On the track temps are usually between 110-120deg C measured at the oil pan for 5-10 laps depending on ambient temps.
Thank you very much for the wisdom. At the moment I dont quite know where my plans for this car will end. I am definitely going to track it a bit in the future. The only real reason I was thinking of getting an oil cooler is because of the fact that I dont really know what I want to do with the car, so I am asking all of these questions to help with my future decisions.

Also, is the engine you have N/A, or forced induction, and what internal parts have you changed, if any?
