Anyone know the stock final drive ratio for the USDM s13 VLSD diffs? ---

4.08 All s-chassis are the same as far as i know. However there are rumors that CA cars came with a slightly smaller rear end ---

You are correct… I found some other intersting stuff too check this out. Apparently different in some of the S chassis. Final drive ratios S13 w/ KA- 4.083 S13 w/ CA18DE- 4.375 S13 w/ CA18DET- 4.363 S13 w/ SR20DE- 4.111 S13 w/ SR20DET- 4.083 S15R w/ SR20DET- 3.692 But then i found some other ones that seem to have some slightly different numbers as well as many more. Z33 - MT - R200 - 3.538 Z33 - MT - R200V - 3.538 Z33 - AT - R200V - 3.357 Z32TT - R230V - 3.692 Z32 - R200V - 4.083 G35 - Sedan - AT - R200 - 3.357 G35 - Sedan - MT - R200V - 3.538 G35 - Sedan - AWD - AT - R200 - 3.357 G35 - Coupe - MT - R200V - 3.538 G35 - Coupe - AT - R200 - 3.357 G35 - Coupe - AT - R200V - 3.357 Q45 - R200V - 3.538 R32 GTR - RB26DETT - MT - F160 - 4.111 R32 GTR - RB26DETT - AT - R200 (Mechanical LSD) - 4.111 S15 - MT - R200H - 3.692 S15 - AT - R200V - 3.916 S14 - KA24DE - 4.083 S14 - SR20DET - MT - R200V - 3.692 S14 - SR20DET - AT - R200V - 3.915 S13 - KA24DE - 4.083 - (Both R200 and R200V) Unverified (but speculated): J30 - 3.916 - (I found several sources indicating this number but I don’t have a J30 FSM so I couldn’t truly verify) R32 - 4.363 R33 GTS-T AT - 4.36 R34 - 6MT - RB26DETT - 3.96 Hopefully this helps someone else too looking for some more easy torque in exchange for some top speed. Also explains why CA’s can feel quick even with less HP. ---

S15R w/ SR20DET- 3.692 Are you sure thats right? For some reason I dont think it is… I could be wrong, but I’m sure its not that…? ---

Yup thats the helical diff. And remember the S15 has a 6 speed. so the extra cog in the box makes up for the longer rear end ---

> [@RS13](#): > > Yup thats the helical diff. what is a helical diff? maybe you know something i dont but the only other style of differential gear cut that i know is called “hypoid”… ---

[quoted from website]Aftermarket diffs come in two basic flavors: clutch-type diffs like the KAAZ or Cusco units, or helical-gear differentials like the Quaife. Which is best depends on what you want to do.[end quote] > **[Project Nissan Silvia Part 3 - Project Cars - Sport Compact Car Magazine](http://www.superstreetonline.com/how-to/project-car/0309-project-nissan-silvia-part-3/)** > > Read all about the Project Nissan Silvia Part 3, brought to you exclusively by the experts at Sport Compact Car Magazine.
