Thomas,
     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
year 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
(My 13B "Cosmo" uses it between Tracy's RD1C and engine like "Bulent" of this group
.....See photo) attached)..........FWIW

On a similar topic...does anyone know how to identify which year 20B I have? I was told ,but have no real way of knowing .

Pat,
     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
housing.........

Hey gang,

I have a core engine I need to identify.
Are there any numbers on the web I can look up?

Thanks!

Pat
