I'm no expert, but I believe that there will be an issue of adapting a RWD tran onto a FWD/AWD engine. Much like the issue with the FWD SR20 and The RWD sr20 trannies.
Usually the truck/suv engines made in the late 80s threw the 90s were made in mexico and made with more leaniant quality standards, like the vg30's and the ka24's
