S4 - S5 TT differences
I'm basically new to turbos, all I know so far concerned normally aspirated motors.
What differences are there between S4 and S5 turbo II's?

Both series of turbo models have a limited-slip differential. Just the method employed in each is different. IIRC the S4 turbo has a clutch type LSD and the S5 turbo has viscous type LSD. Generally, the clutch type wears out quicker, but is more effective than the viscous.
