Torsen Differential

[George Harris]

Well the answers to my previous post regarding the differences between
the 5KCDTQ and the 200Q are much appreciated, but as is often the case,
they point out another area where my education is lacking.

The Torsen Diff came up in a number of posts. What is the Torsen diff?
Is it some sort of 'posi-traction' that replaces the requirement for a
manual lock?

Is it a good trouble free system?

My parts supplier's catalogue shows that the 5000 and 200 both have the
MC engine, although a number of the answers to my original question
indicate MC-1 and then MC-2 engines. Can a transmission with the Torsen
Diff be bolted into a 5kcdtq with the standard MC engine?

Waiting to be educated as always by the aficionados at Audifans,

George
