Ok I just need to know(and I dont' know how to find out) what type of Nismo lsd I have. I got it used and I am for certain it is a nismo just dont' know if it is a 1.5 or 2 way. It has a 48:11 ratio (final drive 4.36). I am stump cause I tried the dealership and other places and there isn't a part number on the lsd to identify it. Please let me know what can be done to find out. Thanks if ya want pics I can get it up.

How do you know it's a Nismo?

does it lock when u let go of the gas???
i have a 2 way and i go sideways evrytime i let go of the gas.
1.5 diff would not lock when u let go of the gas

(do it on a turn as ur exiting the freeway, notice it the tire lock when u let go of the gas)

i have a nismo lsd and it is adjustible (u have to take it apart to change it)

let me know if u need more details on how to change it)

I know it is a nismo cause of the look of it. No other companys that I have seen makes it with smooth and rough surface. Notice the smooth V shape and then the rough darker area around it. Here is a picture. Right now it isn't install on my car which I will be doing tomorrow. I just wanted to make sure there wasn't a way to find out while I have it open.

Awdsr20 thanks for the reply. Just to make sure your nismo looked like mine right?

Well I finally got it installed and it was kinda a b**ch cause I didn't have the right output shafts....one of the output shaft(driver side) that came out of my stock diff was longer so i had to get another short output shaft(passenger side). So I had two passenger side output shaft in my nismo lsd. It works and I am goign to try out that letting go of the gas. I think it still locked up cause I ran it while it was jacked up and both wheels kept spinning. What other ways can I find out?
