    S15 diff casing in s13 subframe

    Evening lads,

    I bought an s15 helical diff for my s13, its come with casing and all, is there any way of fitting the s15 diff casing to my s13 subframe or do i need to either rebuild the diff into my s13 casing or fit a s14/15 subframe?

    Cheers!

    Pretty sure it's as easy as use the s13 rear cover and get some solid bushes. Normal bushes may work.

    P.s. hope you don't want it for drifting.

    Will do for sure pointz, ive got one in my s15 (obviously haha) and i really rate it for fast road and track work, so much more tractable than similarly set up s14s ive driven. Im hoping it will do the same for my s13, ive fitted a 14a engine and box so my ratios should be half decent too .

    These diffs are a dream compared to a VLSD. You'll both love them
