s13 differential into s14 question

[SilviaSR20DET]

I have a s13 nismo 2way diff and wanted to install it on my s14. However, the s14 front bolts have a bushing whereas the s13 does not. Can i just use the bushing and bolts from the s14 with the s13 differential or do i just use the bolts?

Are you trying to install the entire s13 pumpkin, or are you talking about installing the s13 differential into the s14 pumpkin?

You'll need an S14 rear cover too. Just use bolts on the front holes, no bushings.

I was talking about installing the entire s13 pumkin onto my s14. Looks like all i need to do is replace the cover and use the original bolts without the bushing. thanks for the clarification guys!

[SilviaSR20DET]

quick question are the s13 bolts the same size as the s14 bolts at the front of the differential where the subframe meets the diff?

[ManoNegra]

use the bolts from the pumpkin you're installing
diameter and pitch is the same
simple stuff

I dont have the bolts that came with the s13 diff. The only bolts i have are the ones that are currently on my s14 right now. Will those fit?

[mikerbike]

S14 bolts are longer, to fit through the bushing. Maybe go to the junkyard and pull a pair out of an S13.

or just use some spacers on the s14 bolts

Just buy some s13 diff bolts from the dealer.... I just picked some up the other day for like $8 for both. You'd need some pretty big spacers to space the s14 bolts enough.

okay cool i might just stop by the dealer to get some.
