Which 1.9 is easier to make fully mechanical?

Hello I’m US based and I’m looking to swap a 1.9 diesel into a Toyota truck. I’m looking to make an engine fully mechanical with only power to the starter and fuel shut off. Where I live there is no emissions testing. So which engine is easiest to make “m-TDI”? And what pump do I need for that specific engine? I’ve done a lot of reading already but it gets a little confusing when people talk about a hybrid pump and sourcing small pieces from several different cars.

Edit: My goal is not huge power. I’m wanting to build a ‘bug out’ EMP proof vehicle. I don’t want to debate the validity behind this in this thread. Just information would be great thank you. Yes I’m fully aware the 4x4 system in the Toyota is electronic. I have already began making it mechanical.
