Please see the Motronic conversion tech procedure on scirocco.org, as
(most) all your questions will be answered.  The only piece that's missing
(which I'll add shortly) is to use the Motronic fuel pressure regulator,
but you'll have to build an adapter...details to to be posted soon.

Wrong.  Almost all CIS injectors are basically the same, except for
the CIS-III units (Motronic and Digifart) which have different operating
pressures and flow slightly more.  This topic _just_ went through the
VW Auto-x forum.
