4/87 through 89 turbo Z has the same unit, but you'll have to swap the retainer nut that goes in the driver's side side gear from your front diff to the LSD.
FYI, you'll have a hell of a time finding one, nearly all of them get snatched up by the rice-boy crowd to swap them into their non-LSD Z31s, and other R200-equipped RWD Nissans. The ones I've seen pop up on Ebay go for well over $400, and every single one sells.
