LSD swap into non-T P11

I want to swap in a Limited Slip. From what I've read, I need the Diff, Casing, and new half shafts for the conversion. I'm also thinking of a Quaife LSD kit (which fits a stock LSD setup).

Has anyone swapped in a LSD to a open-diff G20?
It was unclear if the Sentra SE-R had a better diff than the one the T comes with, or if it was the same.
