Diff Ratio For An Rb26 Swap

[TriniGT]

I am installing an RB26DETT in my Silvia and am am wondering what diff ratio I should be looking at seeing as it is a RWD application. I have access to the R32 GTR diff and entire rear setup that I am swapping to the S15 rear subframe and just changing the diff covers and I am using an RB25 gearbox. Is the R32 GTR diff suitable for my setup as I am looking for good acceleration from the get go?

Off the top of my head the gear ratios with 4.11 diff gears are something like (all at 8000 RPM)

1st = 75 km/h

2nd = 120 km/h

3rd = 180 km/h

4th = 235 km/h

5th = 310km/h

Might be off by a bee's dick but you get the idea.

Maybe go back to the GTS4 ratios. I think they are 7% shorter.

Didn't check, but if keeping the ABS setup will this R32 diff work? I remember that the GTR has ABS but not sure how it is in the rear subframe. Can anyone enlighten me?
