I have seen a few 13B engines with 12A front covers. Here is a 3rd gen engine
with a 12A front cover. Perhaps this front cover came from a  13B powered first
gen RX7 with the front motor mount. Or perhaps the builder
of this engine modified the 12A front cover.

So % wise it's most likely a 12a cover. looks like the beginning of a 1"
or so water casting spacer and he's using a RWS OMP bypass block as
well. I'm surprised the REW oil pan fits a 12a front cover.

(Thanks for the pic, I've got a customer with a 12a that does 3/8th mile
oval racing at the local track, beats up on a N2O fed, bbc camaro which
is very funny to watch, but he's been looking at going to a 13B upgrade. )
