If I remember right, that engine is a 4.2 L straight six and is naturally aspirated - the same as is in my Nissan Safari. It is one of the most reliable engine's ever built. In the post 1994 non-turbo versions Nissan went to weaker pistons and connecting rods. Still, they are quite the engine. I would check with UD USA on the swap. They have a link to their dealers and part suppliers there. One of them can tell you for sure.
Hey Brown Bear, we also have a Toyota. Lovely little car but no where near as reliable as the Safari. Eats up more fuel than the Safari and keeps my part shop happy. Glad I have an account. SWMBO loves it, so I guess I love to work on it - not!
if you've got an fe6ta motor in the 92, should be straight swap. fe6ta is common for the 2000, but in 92, it could also be a td42t/ti or ne6/6t/6ta. td42t/i both seem to be popular on the earlier models. don't know whether they'll interchange with the fe6.
