limited slip or not limited slip?
I have a 89 Rx7 coupe im not sure what model rx7 it is, it has a sunroof, back stock spoiler, the mirrors with the opening in them, and it has 4 piston breaks, power windows.
so im trying to find out if it has a limited slip diff in it but not sure how to tell.
the car isnt running at the moment.
is the any sign or marks on it to tell?

in 1989 the only 2 models to get a limited slip were the GTUS and the turbo.
the GTUS has no sunroof, and manual windows.
so unless someone put the LSD in yours, you have an open.
the simplest way to tell is just to jack up one wheel and turn it, a non torsen LSD will take effort to turn, open just free spins

The breakaway torque test is the most definitive as you will still feel some resistance even if the clutch packs are toasted or the viscous coupling is burnt.

S5 turbo here, no lsd.
What i've heard is that is was option?
If you are able to disconect the drive shafts, pull out the output shafts, u can see what you have by looking true. If you see a bar, u have got an open diff.

If LSD, it should spin with the other (same direction), but with a open diff it should spin opposite, after what I've seen from my car and others.
But staying put? Might be a stuck handbrake tho

Again, there are diffs that will act open if the rear of the car is in the air. The only sure fire way to tell is by taking it apart and looking inside the differential.

Miata torsen style LSDs are basically a drop in.

yeah so i jacked up my 7 and slapped it in gear and spun one wheel around and it spun both but one went the opposite direction of the wheel i was spinning.
I take it i have a open diff....right?
so does a open diff spend both tires or just one?
I dont want a 1 wheel burn out. LOL!

So will a worn out limited slip...
A worn out limited slip and an open diff will act totally the same...
The difference is you can rebuild a worn out limited slip for a couple hundred bucks in parts and it will work just like new.
You can not just add clutches to an open diff.
You still might have a limited slip.

I know this is a resurrected old thread but my viscous will spin both wheels in the same direction when you spin one wheel, when the rear of the car is off the ground. I have always wanted to put the torsen unit from a Miata in but never have.
