S14 LSD gear ratio

[benlorna]

Does anyone know what the gear ratio is in S14 LSD? There is some marking on the ring gear but I can find anywhere that gives the gear ratio. I am an old American car drag racer ( 67 Firebird high 10s low 11s in the ¼) and have only been in the import thing since my son got me involved. We would go with a low gear ratio (4.11 5.32 etc) and I was trying to educate my self on the Nissan LSD with the RB25det and RB 5 speed.

4.08. Stock rear ratio in 5 speed Rb25s is 4.11. some R33 GTS-Ts came with a 4.33 rear, the automatics I think. and you can get ring and pinion sets from nissan

Thanks,

Short of counting the teeth and doing the math is there any identifying marks on the LSD that will tell you which one you have. I am told the differential is form a skyline but I'm not sure.
