300zx tt diff center

Can anybody tell me if this diff center looks factory or not Thanks

 

here is a photo of it disassembled

 

Def not OEM Z32. Any more markings on it? Definitely a R230 diff? Not many aftermarket centres available for them.

 

ok I have worked out it is a 1way lsd not sure of brand

 

Odd to be a 1 way in a RWD car. They are normally only 1 ways in FWD's.

 

OP is right, it is a 1 way.

Looks similar to a Cusco RS but it's not, unless it's a very old model. The plates don't have the oil flow indents in them, and most Cusco are dual option, ie 1.5 & 2 way or 1 & 2 way. You can set it how you want. This one you can't.
