It has been about 7-8 years, but I used to get all kinds of performance
parts for Rabbits, GTi's and Sciroccos from several companies (there are
lots).  Neuspeed was one I remember.  Most of the performance parts make
power in the higher-rpm ranges (where you are living with that diesel
trans).  However, you are often going to sacrifice low-end grunt (which is
what you really need).  Some things I did on my old Scirocco to increase
off-the-line grunt:

Free flowing exhaust with European GTi 4-2-1 manifold (sound like you have
this already)
Bigger AFM (~100 mm I think)
Larger throttle body, match ported to intake manifold
"Euro" grind cam
Balanced and blueprinted motor with 10:1 pistons
Lightened flywheel

With this setup I used to eat 8v GTi's for lunch, and could hang with the
16v Sciroccos and GTi's up through 3rd gear.

Driving a Vanagon is a whole different thing, though, so I don't know if
much of this applies to your situation...  (i.e. YMMV)
