My aspire has a mazda engine and transmisson but the body is made by kia. l need to know if it will bolt up right to a mazda protege?

It depends on the year and or engine.
There were/are a lot of choices in this area.
But if you are doing a complete power train swap (engine and transmission) the job should be easier. The problems that you may run into are engine mounts, shifter linkage and clutch linkages. The choice of CV axles may also prove difficult but not impossible if you can find a good parts shop that has some one who will help you find the right parts.

they will fit like plug and play but need some little moods on the ignition and might need use the axles from the protege, depends on the year

and from l know aspire is ford

Skip the Kia made crap.it wo not go more than 100K and then completely crap out.it is why Kia say 100K warranty and the cars fall apart at 101K miles
