Stock FD- 2591rpm
3.9 FD- 2738 rpm
4.08 FD- 2864 rpm
4.36 FD- 3061 rpm

I would honestly just go with 4.08. I think that 4.36 is a bit much, unless you plan on making your Z a dedicated track car. I remember when I drove my 350z with 4.08 rear from WA to TX, my RPM's were getting way up there at cruising speed. I think at 75mph to 80mph I was almost at 4k rpm. It was basically like driving in 5th gear the whole way down there.

To fully utilize the 4.36 FD on the strip you're going to need slix, ECU reflash for a rev limiter @ or > 8,000RPM, and a Nismo oil pump. For the week end ST racer/garage queen, these gears are fun as hell and I wouldn't go to anything higher since the VQ don't make any torque. If you daily drive your Z and are slightly concerned w/gas mileage, then you better go for the 4.08 FD.
