Could someone tell me what engine a 1980 RX7 has?  Was it a 12A, or had they
switched to 13B's yet?  I'm looking to buy a junk engine so I can learn
something about rotaries hands-on, and there is a 1980 RX7 I can get my
hands on free.  It's been sitting for several years after a minor engine
fire, and I'd like to know if this would be an OK engine to learn on.
