1. No, the 1JZ was not sold in the US or anywhere else outside Japan.
2. Not much is interchangeable between the 1JZ and 2JZ. If you're referring to bolt-on 2JZ upgrades like turbos and manifolds, they won't work on a 1JZ.
3. NA engines are different again.
4. You don't necessarily have to change the water pump. Some 1JZ's come with a hydraulic pump built into the water pump which drives a hydraulic fan; some people choose to remove this and replace it with a regular water pump from a 2JZ. Not all 1JZ's have the hydraulic fan though.
