Mazda B3000 motor

[songboat]

I want to know if a motor out of a 2003 Mazda B3000 will fit into a 2003 Ford Ranger 4.0

It would fit, physically, but it wouldn’t bolt up to the 4.0s transmission, nor would it work with the 4.0’s computer, any probably other things as well.
But it can be done, you would have to swap over lots of things along with the engine.
