    i can get a complete rear end less diff for the
    S-13 $ 200
    S-14 $ 700

    is the S-14 worth the extra cost for the slightly better geometry?
    Wow… things are expensive there… the last rear end i was going to buy was 80-100$ complete including the diff…

    You should be able to get these out of your local pick-n-pull junkyard for $200 or less, complete with diff and everything.

    S14 is not worth the added cost in my opinion. Not in a Z31 anyways.

    not worth the added cost in initial price that he's been quoted - or are there more costs included in the grand scheme of things?

    Still kinda doesn't answer the question.

    I have an S14 sub frame laying around in my backyard, which is why I am curious to know of any additional cost beyond acquiring the unit itself.

    The s-14 has more width hub to hub. The mounting holes in the rear are slightly different but only slightly. People either stretch the factory bushings to make them fit or there are aftermarkets with the holes slightly offcenter.

    Given the choice for the same price, get the S14.

    Careless,

    In discussions with 1SickZ when we were both doing this swap, I had less notching of the body to do then 1SickZ did. Whether this is because I used an S14 subframe vs his S13 subframe, or because I installed SPL arms instead of the arms he used, I'm not entirely sure.
    The bullshit stops, when the GREEN light drops.

    Only babies cry about the bottle.

    Thank you sir.

    Considering my subframe has absolutely everything except for the diff itself (cables, shafts, rotors, brakes, etc…) I should just buy a diff and adjustable links. I have a JDM S14 subframe with the electronic hicas… not sure how it differs, but I think adjustment ability is better if you use an eliminator bar with adjustable rod hicas replacement links… or so I've been told.

    Maybe something to do in a year or two. My car can use a lot more work in other areas before I even go that far.

    If my rear shocks and springs take a crap, I'll start on this early…

    check anywhere that has front clips from japan land. they usually get cars shipped with the rear end. you could probably get an s15 rear end with vlsd and everything included for 1000… :-/
