220-240 is nothing to worry about. However if you are going to track the car you will need an oil cooler.
I don't think the Nissan one works with the stock cooler in place, but Z1 Motorsports has a nice cooler package that you can get a thermostatic plate and a variety of sizes of cooler and it will work with the stock unit still installed.
You may have warranty issues with the cooler, but you will have warranty issues if you're tracking the car and they find out.
