The engine and motor are the same thing. What are the problems you are having that caused the mechanic to say the engine is bad? What testing has been done? Depending on the issue you normally do not just replace the engine, a lot of problems can even be repaired with it still in the car.
As for what engines fit. It looks like the 3.0 from 03-04 Mazda 6 with a manual transmission are the only ones that fit.
