I think thay said it was 75HP.

Technically, the '74-85 12A is a "12B", and was even referred to as such in some early literature, but it retained the 12A name for marketing reasons. There was no actual 12B-stamped engine.
The 13B, they had no choice. They made a 13A from '69-72, the only rotary to have a different "diameter" than the 10A/12A/13B/20B lineup.
There's no difference between a 20B and 20B-REW, either...

13a was in the only fwd Mazda rotary, the Luce coupe (RE130). Looking at pictures of that with the motor sitting in front of the front wheels with a transaxle behind it I would guess it wasnt the best handling car of all time.

the -REW suffix was used for all of the twin turbo engines, the cosmo shop manuals say 13B-REW and 20B-REW, just like the fd book says 13B-REW.
they call the rx8 engine the 13B-MSP, for Much Silly abbreviations P
