Hello everyone
I have a Mitsubishi express van 4wd currently its petrol 4g64 2.4lt na
I have the chance to put a 4d56t(2.5 turbo diesel manual injection pump no computers) in it, this is a brand new engine from the factory in japan not common rail and 4d56t engines are 30 years old same age as the 4g64 petrol engine

I am taking 3-5 years to go through Asia and Europe and the Americas, so I'm wanting to hear peoples thoughts on what would be a smarter choice, I understand the differences from petrol to diesel things like petrol has more serviceable items and more things that can go wrong but cheap and easier to fix, diesel better fuel economy fewer things to go wrong but if they do much more expensive to fix, as its an old diesel high sulphur diesel shouldn't be a problem
both engines are old 25years old the diesel is brand new from the factory and the petrol engine will be completely reconditioned, petro engine is an electronic distributor and had very few sensors, it was the first efi 4g64 Mitsubishi built, so its basic and very reliable, not may electronic items
diesel basically just needs fuel and air and it will run under water haha, of course, fitting water separators to both the main tank and aux tank and high-quality fuel filters will be a requirement


so as far as being able to get fuel and general thoughts on what could be a better choice overall, not interested in power or speed just want reliability, fuel cost is not a concern either, it costs what it costs and if that's what I want to do these are the costs associated with my travel
