OK, here is a LSD I cannot identify.

It looks like NISMO one....

Does anyone have clue?

LOM55 is the stock number for a Power Brute 240SX LSD, unfortunately the info I have doesn't say R180 or R200. Power Brute is made by the same people who made them for Nissan so it very well maybe exactly the same as a NISMO unit. If you want to take it apart you could see how many clutches it had and that sort of thing.

Looks a little different than mine from a 300ZXT. Is it possibly a 2 pinion out of an R180? I've known 2 people who had the 2 pinion unit for the R180, and both broke it. One of them also snapped a mustache bar in half, the other wasn't too crazy with it but it broke anyway.

Looks like a 2 pinion R180 to me.
