Hey guys...ok so everything is prety much bolt on and modify alittle but from working on Toyota Supras and have done a few transmission conversions, the supra has 3 different rear differentials with different gear ratios.

One for the Automatics, One for the manual NA, and one for the Turbo models

i cant seem to find any info on the 1995+ 240sx s14 rear end besides 409:1 ratio....aer they all the same with the only difference in LSD or not?

the reason i ask for those who arent familar is that the power transfered to the wheel on a auto to manual conversion will make your car slower and have less HP to the rear wheels. and for you kiddies, slow 1/4 miles!

so whats the deal?

The 95 240SX has 4.08:1 gearing for both the open diff, and the vlsd.

the R200 VLSD is the same on the NA 300zx, it fits in s13's and s14's aswell if that helps at all.

caper

so you are telling me if i do the conversion it will be as if a manual to begin with? no other components are different or will remain automatic components?>

SO answer this directly..the Automatic rear end is the same as the manual rear end? speaking NON-lsd or LSD models

RalphCare

maybe u'll just have to change the driveshafts?

thats what im guessing in case the auto is a little longer, and i think dayna said in a post that where it bolts up is a little different, some bolt holes wont be used or something?

All U.S. 240sx's had a 4.08 final drive. Japanese/Australian/Everywhere else that didn't get screwed, had some different choices. They had a different final drive for the N/A's, Turbo's, and the AT's.

S13, S14, and S15 (varietta only) 5 speed:
N/A model - 4.08 (same as ours)
Turbo model - 3.69

S13, S14, and S15 AT:
N/A model - 4.08 (same as ours again)
Turbo model - 3.91

S15 6 speed:
Turbo only - 3.69

These are all R200 units, but the only difference is the S13 and S14 use the VLSD while the S15 uses the HLSD.
So you can use one of those if you wanted to change the final drive.

Like others said, you can use the diff from the N/A Z32 as well... Same final drive as ours already. The J30 diff will fit the 240sx as well. The J30 has a 3.96 final gear so you can change it with that also. The Z32 diff will fit the 240, but it requires a little bit extra work. It has a 5 point star looking output flange, so you will need to use the Z32 output shafts as well if you want to use that. The 94+ J30 has 3 pairs of bolts on the output flange, like the 240... so there would be no need to change the output shafts. When using the J30 LSD the only things you need to change are the J30 rear cover to the 240 cover because the J30 uses 2 big bolts instead of 4 small ones to mount in the rear. Also you need longer bolts for the front mounting because the J30 diff has thicker bushings than the 240.

Have Fun
