I think the LSD was standard equipment on all models.

 

Pardon me for asking but what is the LSD?

 

Limited Slip Differential

 

Let me check my window sticker, but I am just damned sure that all FDs have limited slip differentials.

Uh, how are you checking yours, what makes you think it is going bad?

 

The FD comes with a Torsen diff. Go to

http://www.torsen.com/ .

It does not have clutch plates but gears. Was first used in tanks and trucks.

 

I KNOW I have an LSD

 

I just talked to a friend of mine that is a mechanic and he went to school on Rx7s. He told me that the FD's all came with limited slip on them.

 

Yep, they all have the torsen type...

You haven't said why you think your's is bad... You only doing burnouts with one wheel or something?

 

Mine came with Windowpane........or was it Blotter or.........????

 

Before you buy the Kaaz have a look at the Guru, I use one (here in OZ) and it is great!

As other have noted, they all came with Torsen Diffs as standard. Interestingly, in Japan 2 different types of Torsen diff were offered on RX-7's. Standard models like the RZ and RS got a "Heavy-Duty Torsen Diff" while the other models were listed as "Normal" Torsen Diff.

 

What is this school on RX-7's that you speak of???
