Usually in a 911 with LSD (old ones), oil is something like 75w140 (not sure about the exact values but sure about the range). I can check if you need the exact values.

Hi Sebastian,
Yes, very sure: besides the fact that this is not an old tranny 911 type with porsches' own syncro system (which indeed needs a different oil), its actually counterproductive to use thicker oil or specially formulated LSD oil:
The latter usual has friction modifiers, which reduce the effectiveness of the friction plates. In that sentence alone, you can see/read how weird this is...
Those 'special' lsd gear oils were made because they reduce noise of the friction plates (in slow corners or in the parking lot), which is very liked by the typical Porsche owner who wants a comfortable a relatively quiet car.
I just want performance
