89 Turbo diff type... Clutch or torsion?
So I'm going to change my diff oil and I see there might be a difference between the Torsion and Clutch type of RX7 differencials for oil requirments. I know we all have our oils in mind, however, I'd like to use Redline's 75W90NS oil which seems to fit the bill strongly for Torsion style differentials which do not require LSD friction modifiers.

So what does everyone think?

The 89 Turbo has neither a Clutch type LSD or a Torsen LSD.

It has a Viscous LSD which does not require any special gear oil.

You would use 90W or 85W90

It's an OK diff. I swapped for a low mileage S4 clutch type turbo diff and I'm much more pleased with the lockup.

Guess a former owner changed the diff on this car. Sux the front diff mount was shot.
