Nismo 1.5 Way LSD GT Pro
 

I just bought this diff for my 2013 sport model, the oil that comes with it is motul 75w-140.

Is this the recommended oil to use or is it better to stick with the 75w-90?

Also anyone with this diff have any issues?

Stick with the 75w140 for a clutch dif. The 75w90 is just to thin and won't last long due to how hot these diff's get.
I was running 75w90 in mine and didn't know it. It was Green in color. I just did a fluid change and the 75W140 and it is Blue.
This is how I could tell the fluid was different. 10k miles and it was cooked.

I would also pick up some Redline Friction modifier to help with the chattering during tight turns.

Alright cool, would you recommend redline oil? Or is the motul oil on par?

Motul is better. I do use the Redline friction modifier.

Cool, will stick that Motul then.

Is anyone running this LSD? Just want to know if its unbearably noisy or just a bit more noisy?
