Bought this diff from a nice chap who said it was a "Motorsport" diff & installed into a 1996 993 Turbo. He was also told the ramps were 65/25.

Wondering if any of you Gurus can tell me what I actually have here?
Part # on the case reads: 950.332.083.01
What do those ramps angles look like to you?

911SLOW

It's a street dif from a 993 carrera4 /4s / turbo G64./20./21./51

No longer available as the part has a successor with part number"950.332.083.03"

The new one is from GKN with 22/40%..

Older 993s used ZFs 25/65%

Thank you Slow, you are fast. This one has GKN cast into it. But the part # says it's older? hmm

Edit: did a quick photoshop with a protractor... original photo is not dead straight so angles are a bit off.
The ramp angles are referenced from the parting line of the two halves or ??
40/70 ish ? or 50/20 ish?

Edit #2... ah you are talking % and I was thinking Degrees.

Just to confirm what was already said it is a 25/65 LSD from a 993. It's still got the original 2 plate carbon clutches in it, which worked well but didn't last more than 25k mi. You can remove that big thick steel ring and convert it to a modern 4 plate specification when you rebuild it.

Thank you Matt, you have a PM.
