But to answer your question, it depends...
The engine i put in my Samurai came from a 1995 4 door sidekick. I drove it around the yard a little and it was peppy. The rear axle from it went in another Samurai we have and it's "beefy" comparably. A lot of them came with 5.13 gears stock.
What do you really want to do with it and what exactly is it you're looking at?
