Run a 40w oil keep temps below 130C and you'll be sweet.

Street use on a MT there is no need to touch any of the cooling system (unless maybe you've covered half the radiator with a fmic or pushing huge boost on upgraded turbos). Track use an upgraded cooler is recommended pretty easy to get to 135-140C in my experience.
