Convertinga Mazda B2000 1984 F/MA engine to an FE?

I have just been shopping around and found an FE engine that is complete blown of its t!ts.
But my current engine is a F/MA, Does anybody know if the intake manifold and exhaust manifold are the same on both blocks, and will it bolt to my tranny and engine mounts the same?

Mazda B2000 1984.

Ok so the motors are complete different and will not work.
Anybody have an opion on the cheapest & easyest engine to swap with, and what do i need?

ive got a B2000 and a B1800 one of which is ma engine and one is fe engine, both have the same mounts and even have identicals heads, block is only difference i can see.

I need help as well, i want the FE3 motor swapped but i have a f/ma 2.0l is there anyone who has done the swap and how involved is it with custom stuff?
