Swap NISMO 7A differential with my original 2009 7A diff?

RamseyJ

I can't directly answer your question but my educated guess would be yes and cruise control should work.

I had an 2012 g37 7A (open diff) and i swapped in a 370z manual diff for the final drive advantage. If i was able to pull that off (cruise control worked), which is more complex than going from a 7A to another 7A, I can't imagine you having a ton of issues. They should have the same flange and everything but I'd see if you can confirm. I do hear people lose cruise control when going to the 4.08 final drive, but haven't seen any issues swapping OEM diffs.

Just my personal experience, hope it helps.

What you have to watch out for is the bolting on the axle stubs. Is it through bolts with nuts, or just bolts that thread in?

I read about this issue. The 2009 is different than the later years, so will have to either swap out stubs, get new axles, or get something machined. Seems like the consensus is the design of the later version was much easier to deal with, so I will probably look to change to this.

The NISMO 7A differentials can be found cheap, so it seems to makes sense to swap the entire unit instead of trying to mess with the old one.

Thanks for your input, was hoping someone who had done a swap would comment.
