s13 LSD in a s14

does it work? Im looking at one now but i am not sure if it will fit... I know theres some problems putting a s14 lsd in a s13, so is it the same to put a s13 lsd in a s14?

should fit no problem

then why does the s13 have trouble fitting the s14 lsd?


posted on freshalloy about the s14/j30/z32 diffs having bushings on the
front that need to be replaced with metal spacers. The reasoning behind
this is that the s14/j30/z32 diffs are mounted by bushings to the subframe
where as the s13 is metal on metal to the subframe. When replacing just the
rear cover the front points are bushing mounts while the back ones are 4
small solid mounts. Also note the rear cover is aluminum and rather fragile.
If the front end of the diff is allowed to move then it puts stress on the
solid mounts on the rear of the diff. I will be getting metal spacers
fabricated for this purpose to install my s14 Nismo diff in my s13 since
the s14 subframe won't swap over without special eccentric bushings.



^^thats what it says about putting a s14 lsd in a s13...

the s14's have longer bolts that mount it to the frame up towards the front of it. if there is a problem its just a matter of going to a bolt store for 2 bolts.

so is that a lot of work or can i handle it?

ya you are right...the s13 has the 4 bolts in the back and the s14 has 2. so just swap em and get the longer bolts for the front and you should be good. the back cover is easy. just 6 bolts or something and make sure you put a bead of liquid gasket. might as well change the fluid while its out. i think it takes like 2 qts???? good luck

no you need to put your stock s14 rear cover onto the S13 3rd member you want to swap into your car.

Bingo.


Also instead of buying new bolts just shim the S13 with washers or something - ghetto SPL Solid Diff Bushings
