S5 is when they switched to the Torsen(helical viscous...) so you have a clutch type LSD unless they happened to install the Torsens late that year which i have heard nothing about.

Torsen is a brand name of helical differential. It is not a viscous LSD.

S4s have clutch type LSD.

Helical and viscous differentials are completely different. S5's had viscous diffs and FD's had Torsen helical diffs. Only the Infini IV FC's got a Torsen diff, the same unit that was subsequently used in the FD's.
