How can I tell?
How can I tell what year 12a I have? I bought a 79 rx that doesn't have the original motor so I'm trying to find out what gasket set I need...

Hope this thread helps...Its basically the difference in the engines. But does your engine have a thermal reactor? That would be the easiest to tell that I can think of? It would be a 79-80. Or look at the exhaust system 79-80 had a heat exchanger newer ones had cats.

AFAIK there is now only TWO RX7 12A spec'd engine gasket kits -
-for the 81-82 FB with FMOC. I use this kit for the 79-80 RX7 12A.
-for the 83-85 FB with beehive cooler
