spectre5 isnt really related to the protege5 at all.... it just looked like it alot, they share the elantra chassis. And the Elantra beta2 2.0 motor.
The only kia's that were mazda related where the 94-97 sephias, they had mazda 1.8dohc bp motors, and it wasnt really a mazda built motor. i hear it was just a direct copy built by kia.. but it was exactly the same in and out.
That Spectre5 is all hyundai...which is still good!
