Upgrading the old 74 fox

[Swann, Benjamin R. (BSWANN)]

Just read this post from Ti, but basically this is what I was trying to say:

[The 16V VW engines (all except the Scirocco) are not a drop-in either.
The throttle body is on the wrong side of the intake manifold, so would
require some creative plumbing.  The Scirocco manifold has the throttle
body on the correct side, but is angled funny and will not fit the Audi
factory CIS air boot.  Assuming, of course, that the Audi Fox in question
has CIS.  If not, then there is a lot more transplanting to do.  Moreover,
the battery would interfere with the 16V manifold, so the battery would
have to be relocated.

I looked into all this while working on my 4000 project...

It's best to start with a newer Audi with the 4-cylinder engine in the
correct (logitudinal) orientation, so that the hassles of plumbing
and other ancillaries do not become problems.  Audi did sell a 16V 4-cyl
version of the Audi 80 in Europe, but sourcing parts from that would be
difficult.
