no, they're not all 13B
there was a 12A used from 79 until 84, I think. Then for the last year of the 1st gen, they put a non-turbo 13B in it.
The 12A was used in all US 1st-gen years, 79-85, in the S, GS, and GSL(LSD, Rear discs, fully optioned) models. The fuel injected 13B came for the 1984 model year, in the flagship GSL-SE model, which was around for the remaining two years of the 1st gen.
