    8" 4runner diff swap into a Corolla?

    So I'm trying to figure out some LSD options for my X3 Cressida. The stock diff is a 7.1" and as far as I'm aware, nobody makes any aftermarket diffs for it? And I don't think I can just swap out center sections to something bigger.

    In a perfect world, I'd just swap out to a 7.5" out of a Supra, but since those are getting hard to find, I've pondered an idea. I have an 8" 4Runner rear diff just laying around and I was wondering if anyone has ever tried swapping one into a Corolla? My primary concern will be whether or not I can make a drum setup that will clear 14's seeing as they're factory 16"

    Does anyone have any experience with this?

    Is the width a concern, compared to the stock diff? I know the earlier 2wd pickup 7.5 diffs hold up to v8 abuse, if the 4R diff is too wide.

    This is probably not super helpful, but TRD did make an LSD for the 7.1" differentials, part number 41301-MX001. It's long discontinued, and it's probably harder and more expensive to find than swapping in a different sized differential, but it exists... somewhere...
