12A or 13B What years.
Can anyone tell me the years for 13Bs (early and late) and 12A. I've been talking to a guy on the interenet that says that he has a '80 13B engine out of an RX7. I thought the only 13B 1st gen's were the '84-85 GSL-SE. He quotes out of the "Mazda RX7 Performance book" that also states that 79-85 1st gens are considered 13Bs. I've never heard/read any of this.

He's wrong. 12A's in all 79-85 RX7 models. And you're right, the 84-85 GSL-SE models had fuel injected 13B's.
There were early 4 port 13B's like in the REPU's, and some of the older RX cars.
