The engine you're looking at is a C223T series. It's generally considered a good little motor, but no powerhouse. Putting it in a second generation Trooper would result in you having a dog of a truck, as the later models are notably heavier than the original applications of these engines. Obviously, the easiest/best swap would be to another Isuzu P'up. Second would be a first gen Trooper, but that doesn't give you the pickup you're looking for. Anything past that is going to involve at least some fabrication, I would wager.
Others here are more familiar with what goes into a swap, and other potential applications, so I'll let them speak to it more fully.
