Yes, it is the same.

I got an used diff from a manual 350Z and installed the 4.08 set up.

Now, my 370Z 7AT is incredible in the sequence "1st-2nd-3rd gear"

.

Very very very short gears and quick shifts.

Note: i added the sprint booster to the throttle, other great modification if you like to drag the 7AT car
