I'm going to be getting a Nismo LSD and 3.9 FD in a few days here. I have a couple questions about the installation part. I did a search and found alot of threads about the 3.9Fd but answering my specific question. If I did happen to miss the answer in a previous thread I apologize and please point me in the right direction.

Anyway heres the issue. The Nismo LSd comes with all the parts needed for the LSD install but the 3.9 needs seperate parts. It's my understanding that I need the pinion seal, crush sleeve and pinion nut; and the ring nuts, front/rear pinion bearings and carrier bearings if the car is of a certain age.

Now my 06 base model Z only has about 2010 miles on it is it necessary to replace the ring nuts, front/rear pinion bearings and carrier bearings for a car with this few miles? I don't want to cheap out on anything but I don't want to go spending money frivolously if I don't need to. I'll be getting everything installed at Z car garage.

Any help would be much appreciated. Thanks.
Oh and if I'm forgetting anything please chime in.

 

you'll only need what we call the install kit 1 - the crush sleeve, pinion nut and oil seal

the rest you can easily reuse as your car is so new

 

Ok thats what I thought.

 

tell me how it goes over at Zcar Garage, im also interested in doing a similar setup, i had them dyno my car right when i got it. they seem pretty cool over there

 

This isn't totally correct. You'll also need some shims of some size, and you can't tell what size until you ahve the car opened up. This has been discussed many times.... the best place to have the work done would be one that has on hand every size shim. Example (as much as I hate them) the Nissan dealership.

 

Yes I know about the shims. I talked to Rob at Z car garage this morning he said they had the shims and all the necessary installation parts available.

I did call a nissan dealer just for the hell of it they wanted over 1K for install which is ridiculous.

 

I had my 3.9 installed at ZCarGarage. They did a great job on the install and are very professional.
