Here you go everyone: The engine
should be stamped on all the rotor housings and sideplates. Look on the top of
the rotor housings where is says "Mazda 20B"
Pre A code: 3
digit numbers only, no letter
A code : Letter A and 3 digit #
B code
: Letter B and 3 digit #
All of the above are small dowel pin land
motors
C code: letter C and 3 digit #
D code : letter D and 3 digit
#
The C and D code have the upgraded sideplates, thicker dowel pin lands.
Approx: 4mm thicker

Try Brian Galloway in Calif.........He deals in Mazda parts and is very
knowledgeable in
the 20B models and
the differences between them.........Improvements were made in
the

models............For our use in aircraft the upgrades probably are not as
important as
we are not severely
stressing our engines like the racers (Auto) do.........I do know that
the
later model 20B's
sell at a premium...........The last time I corresponded with him he
had
both early and late
20B's for sale............I bought a 20B auto trans bell housing from
him

it between Tracy's RD1C and engine like "Bulent" of this

If your core engine still has the waterpump on it count the number of
bolts
on the
pump........86-88 13B has 7 WP bolts...........89-91 has 8 WP
bolts.....
93-95 13B has an all aluminum WP.......This is quick and dirty but there
are
other ways if WP is
missing...........The 86-91 WP is cast iron bolted to
alum
