The Generations
There have been three generations of Miata so far, and they are referred to by their chassis code (NA,NB,NC) or by (M1,M2,M3). Defining characteristics are the flip-up headlights of the NA, the swoopy shape of the NB, and the fender bulges of the NC. The first two generations are very similar, some argue that they are the same car, as Mazda could not afford a total redesign for the NB. The biggest change within a generation was in 1994, when Mazda swapped the 1.6L to a 1.8L. With the NA and NB, many parts are compatible between the 1.8L powertrains. With the right hardware, hardtops are compatible from ’90 to ’05. Suspension components are generally compatible, even if the NB shock mounts are quite a bit different. As such, parts for NAs and NBs are extremely cheap. As with all cars, the Miata has become heavier, safer, and more powerful over time. The newest version weighs 2,450 lbs, the first weighs 2,150 lbs.
