Is there a difference or are they all limited Slip? Nissan one is like ~ $500 and how much will it approximately cost to install. I don't know a lot about this so any help would be greatly appreciated. I think Cattman is selling the Qualife one for $1,500. Btw I have a 2K1 5spd

Thanks...

 

I had the Quaife Differential installed on mine and it has got to be the best mod for the $$, after boost of course

I got mines used for about $800 or so. Defintily worth the investment.

 

Quaife is the Diffy of choice.......

 

The Quaife is a true locker. It's the best of the 3 however you will need to buy bearings and a speedo gear and the whole thing plus install isn't cheap. The bearings are about $50 each(you'll need 2), the gear is about $20 and the install can run anywhere from $300-$600.
