180sx/200sx/Silvia Sr20Det diff. gear ratios - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

and the big question is ; what did your cars with the SR20DEt's come with for differential gear ratios
Ideally when you go turbo you want to go lower numerically to keep your Turbo in spool longer thereby getting broader torque and Horsepower band.

inquiring minds want to know :biggrin:

thanks in advance

S15 and S14 have the same ratio sets as appropriate:

All S14 turbos have a Viscous LSD, while the S15 manual turbo uses a Helical LSD. The S15 Auto retains the Viscous unit. Most normally aspirated cars will not have an LSD.

Gear 6MT (S15) 5MT (S14/S15) 4AT (S14/S15)
1 3.626 3.321 2.785
2 2.200 1.902 1.545
3 1.541 1.308 1.000
4 1.213 1.000 0.694
5 1.000 0.838
6 0.767
Reverse 3.437 3.382 2.272
Final Drive:
3.692(s15 6speed) 3.692 (s14/15 5speed) 3.916 (auto)

n/a they do, but the sr20det has a different final drive.

thank youu ca18guy, this is exactly wanted to know meaning that for all intensive purposes if we are A, going to turbo our cars here in the states then we should move down to a 3.92 our lower rear end ratio to offset the increased horsepower and by doing that like i posted earlier keep the Turbo spooled up  longer.
very cool.:)
