What you are describing is not the Torsen (Torque Sensing) LSD. The Torsen
uses worm gears for the limited slip action. I do know that some FWD cars
use the viscous type LSD you describe. I don't know of any FWD cars with
Torsens.

Classic Motorbooks has the book "Alleggerita" by Tony Andriaensens on sale
for 50 USD, half the regular price. It's a detailed book covering the GTA.
