Hi all!

Anyone with knowledge as to the interchangeability of the LSD differential case found in the R200 rear end of the 2004 350Z and the open differential case found in the R200 rear end of the 2003/04 M45?

Thanks!

Check the output flanges. I bet they are different.

The issue is the differential case which is contained inside the differential carrier (AKA gear carrier, or "pumpkin"). The case, AFAIK, is the component that either makes it "open" or "LSD."

The more I research it points that this is the item that determines open differential or limited slip.

In the 350Z, the base model is open differential with an R200 carrier. These can be upgraded by replacing the 2-pinion case to an LSD case. The M45 uses the R200 carrier with an open differential case.

And I may have found a candidate: http://www.quaife.co.uk/Nissan...ntial

I referred one of the M mebers to them and he said no dice. But I bet enough $ would produce a solution.
