Lsd Problems

[28turbo]

Hi all i have a 1995 series 1 gtst. Was at the drags not long ago and found out that only one of my wheels spun while doing the burn out . I thought all of these cars had lsd in them??? Does mine have one and just doesnt work?? How can i tell? If its not one can i just buy a replacment one and just bolt straight in or does it need more then that?? Thanks.

yeah pretty much all of the factory nissan LSDs stop working after about 50,000klm, they just become SDs

depends how much of a problem it is for you - a new mechanical diff is about 1500 installed but will last much longer. no point buying a second hand LSD it won't work either

Am i able to get rebuild kits for the standard one or not worth it???

You can shim the standard viscous centre to improve its performance (there's a thread on how to do it in the DIY section). In my opinion it's not really worth it, as it will wear out again and be open wheeling in no time. If you're going to pull the diff apart to shim the centre, you may as well replace the centre with a better one. So I guess in order of expense you have 4 options:

1. Shim your current centre, cost $50.

2. Replace the centre with a Helical (Torsen) centre out of a turbo S15. This is what I have done in my car... I have written a thread on how to do it (and the benefits) in this forum. You will need an S15 diff and half shafts - it cost me $250.

3. Replace your diff centre, half shafts, and hubs with the same from a R32 GTR. If you can get these at a good price, it is a very good option as the R32 GTR diff is mechanical and has stronger half shafts. Though expect to pay between $500 - $1000 for all you need.

4. Replace your centre with an aftermarket 1.5 or 2 way Mechanical. Expect to pay upwards of $1000 (new).

As I said I went for the 2nd option. I'm very happy with the diff, it has a gear type centre that will never wear out, and by design the diff equalises torque between the rear wheels - So when you go round a corner, the outside wheel (which is rotating faster) gets more power applied to it, to equalise the torque with the inner wheel. This makes for a very good diff for street and circuit driving, as it helps drive the back end of the car around the corner. Options 3 and 4 are better if you're into drifting.

Hope that helps, Ryno
