From what I have read on these forums so far is that the majority of modifications will have some sort of adapting bracket and/or fabricating involved to mount the engine.
If you have an issue with the revs you are at to maintain 110 km/h. There are a few points you need to consider before you do anything.
1 - Component strength: Can the current drive-train handle the power that can be delivered from the 2.0?
2 - Gearing: If you currently manage 4000 rpm at 110km/h and decide to mate a Viper V10 to your gearbox and change non of the drive-train that same viper V10 will be running at 4000 rpm at 110km/h. And that will be a gross waste of power and fuel for highway running. The same will happen with any other engine if you do not change the gears or final drive.
3 - The small engine was designed to rev high. Which is why the gears are short. The power and torque are further up the rev band than diesels and highway cruisers. It does not necessarily mean that you are running inefficiently.
You often hear about swaps with the 1.6 from the Vitara/Sidekick/Escudo. But if you leave the samurai gears and final drive in you will be running the larger engine at the same rpm.
Just as a guess if the 2.0 Vitara motor can be bolted in then it should be possible to slot the 2.0 V6 and 1.8 sport motors in as they are all from the Sport chassis Vitaras.
Point number 4: You also would have to consider all the wiring and space within the samurai frame to fit any other engine.

Reason: Forgot points. Forgot to proof read.
