4.3xx Final Ratio Diff for S14

[Asil]

Hi there,

I've been searching for a diff swap for my RB25 (NEO) powered S14 Silvia (EDM spec) as the gears are too long!

EDM spec S14's coming with R200V diff from the factory and the final ratio is 3.69 and i need a diff has 4.3 - 4.4 final ratio for my S14

As far as i know R32 GTS-T has this diff but i am not sure how hard to swap it on to S14 chassis. I have searched over various forums but couldnt find a reliable data.

If anyone shares his experiences on this issue i would be more than happy.

iirc its like the s13 diff with different output shafts for the axles...you should be able to swap the shafts for your s14 ones to use your current axles

nearly all the skyline diffs have 5 bolt output cups so would require you to also fit skyline shafts. some really rubbish spec skylines come with 3x2 output cups/shafts. but most manual skylines have 4:1 ratio its only really the automatic's that are 4:3

some Nissan Serena will have a 4:3 ratio diff and the 3x2 cups/shafts. I don't know if you have those in your country though

Yes, European SR20 Serena's having 4.3 Vlsd so it can be bolt on to my S14
But we dont have this in Turkey and i have no idea where can i find it.
