That system will probably do the trick. I use the M54 BMW Motorsport housing, some AN-10 lines, and a Setrab cooler. I do suggest ditching the SS braided lines for something that's much easier to fabricate and route. I've been using Earls Pro-Lite 350 and then wrapping it with Russell Wrap-It Wire & Hose Protection.
Without an oil cooler, I was running around 280-300F oil temps. With the cooler, it's 220-230F. I even have my oil cooler mounted behind the radiator, so if it's in front, you will probably see something less than I do.
