Changing a pick-up engine - which one?

We are going to equip a pick up truck (Nissan Z24 - an old model) with a diesel engine. There are two to choose from - a 1.5-litre diesel engine with 200Nm and a 2.0-litre engine with 252Nm. The car has a kerb weight of 1550 kg. Would you please help us which engine is suitable roughly? Keep in mind that users of this car expect to load this car up to 2000 kg normally.
Definitely go for the bigger engine. You'll wear out the smaller engine faster, first its turbo, second the engine itself.
