I remember recently reading some a thread about the type of diff fitted to the s2k, ie explaining regards 1.5way,2way etc and how it works, tried the search every which way but getting no hits, can a poster remember were it was posted.?

 

A torsen diff:

Ta Dembo, but this bit I understand, but needed to know what type of diff, ie 1.5 or 2 and in what way it works, I seem to remember some talk of does it work in forward and reverse and how it distributes the power when slippage happens.

 

I was going to explain, but this guide is much better:
