the main reason to ditch the old motor/tranny:
its heavy as $hit, and super hard to find parts for. cast iron block and head, then usually the tranny is all cast as well. a supercharged 22r and a aluminum 5speed are lighter then just a 18r. most parts for any 20,22r, or 22re, will work for each other, and they made 2Xr's from 1975-1995, and still in production in mexico.
if it has a "R" series eng most any newer one will fit with mild fab if that.
i think its a lil early for a 18r, so you might worry about the rear end, but that depends on whats in there and how you drive it.
i replaced a 18r and a A40 (auto) with a supercharged 22r hybrid, and a 85 supra aluminum W58 5speed. the ONLY fab i did was to drill 2 holes in the tranny mount bracket.
the writeup is here somewhere if ya dont belive me.
