300ZX NA rear diff

[luke91]

If anyone has a 300ZX NZ rear end, how do you like it?

Does the stock diff work well?  Do both wheels lock up every time?  Do both wheels lose traction at the same time, too?

I'm trying to find a good replacement for my open diff in my '91LE.  

thanks

Going with a 300zx rear end is a kinda expensive way to do it. You will have to pay for the differential (usually $300) and then you have to get output shafts for it ($150 each from Nissan).
I would go with either a 240sx LSD or an Infinity J30. I think it's a J30. Someone needs to confirm that.
Both of those differentials will bolt right in, not needing different output shafts.
As far as the worthyness of them. I don't have LSD, but people that do say it is great. I think PSI240sx dropped 1second off his 1/4 mile time from a swap to a factory LSD.
