Actually, my understanding is that the Protege and Escort don't really share any engine parts. The Ford 2.0 and the Mazda 2.0 are completely different. But I really don't know. I just remember reading that on another forum.
all protege engines are all mazda. the mercury tracer and ford escort for certain years shared a BP engine designed by mazda, but that was early/mid 90s. the 1.9 liter in the escort and tracer were all ford. the 2.0 ZETEC and the 2.0 in the ZX2 are all ford. no 3rd generation protege whether it be a 1.8, 2.0, 1.6 or msp uses a ford engine, all mazda design.
the newer focus and mazda3s share components between the engines on the duratec platform but they are not identical car to car.
