2144 to 2226cc?

["Wm. Josiah Erikson" <werikson@hampshire.edu>]

Just curious,
    I used to own an '83 5-cylinder Quantum that was 2144cc, and the one
that I have now (the '87 Syncro) is a 2226cc engine. I assume that Audi
switched at the corresponding time, whenever that was. No? Or was the
2144cc engine VW-only or something. I doubt they'd do that. When did
they switch? Just curious because one of my Audi people told me that the
only difference in engines between the car I had before and the one I
have now was the intake manifold and exhaust. Obviously, he's at least
slightly wrong.
    Are the archives searchable for this sort of question and I just am
too stupid to figure it out?
    TIA,
