I recently purchased a differential which was supposedly a 2way Re-Amimeya for a turbo model. Received it in the mail today.
Disassembled it to double check the condition of the plates and internals, and this is what I find...





Looks an awful lot like a stock 1way S4 Turbo Clutch-type to me. Pinion spider ramps seem to be a dead give away. Can someone confirm this for me???
I've never taken an FC clutch-type apart, or seen the guts of it. I assume this is just a stock s4 Tii diff, but I figured I'd check with you guys anyway.
The part I am holding in the third picture seems like it could be adjusted for certain stub shaft lengths. Dunno really.
I'd like to make an accurate identification of this diff before I return it.

Can you guys help me out??

 

Anybody?

 

Upon further inspection, It seems that the piece in the third pic is some sort of thrust part that allows you to adjust the pre-load of the clutch plates. Three different positions/settings that can be changed while the unit is sealed, using the 3/4" hex head to raise or lower the position.

Were the stock units adjustable?

 

the center pieces directly in the center of the assembly aren't factory pieces but beyond that i have no experience with that type of locker.

it's definitely not a 1 way or you would have 2 outer gears versus the center locking bit.

 

Well it actually does have the 2 outer gears, on opposite sides of the spider gear assembly.

The reason why I see this as a 1way is because of the spider gear cam ramps:
