ive looked for a while and i just cant find the info. i was wondering if anyone knows weither or not the lsd in a 1988 n/a gxl is a liscus or helical lsd. anyone know?

 

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.

 

I thought the torsen and viscous were different?

 

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

S4s have clutch type LSD.

 

thanks dude, learn sumtin new everyday.

 

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.
