Why can you not make a 1990 miata into a 1.8 1994 miata. The body is the same. I understand the brakes are different too. Just confused due to the BMW and RX7 combo's out there.

This is an example of a percetion that could become trouble. My unsderstanding is that the 1990 body is NOT the same, and that making a 1990 1.8 would result in the lightest best handling Miata out there, with the bigger motor. This would clearly be an issue, and they are on seperate spec lines for a reason. This is one of the "unintended consequences" that could result in the VIN rule change.........
