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.

 

what about the LSD thats in JDM Efini Model, I thought that was a Clutch type although mine hasnt got a tab on the filler but that doesnt mean anything

 

Ok so can I just put some 75w140 in mine? Is this diff a POS?

 

You would use 90W or 85W90

 

its is a clutch type out of a s4 just so you know

 

it is? ok who the hell asked you? HAHA ok thanks.

 

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.

 

is that what that was, damn
