Sean,
Defile my Van?
Wow! That's pretty heavy stuff!
I went though the same stuff about 2 months ago on the list, categorized
as "instant horsepower".
Boy, did I catch the rash of Ca Ca for even thinking of any bizarre
ideas to increase horsepower!
You do have an advantage, in that Fast German Auto has a computer chip,
for your Digifant set up, and with a set of ported and polished heads,
some big valves, and a mild cam, you should be right where you want to
be as far as a little extra HP.
I'm pretty much stuck with improved heads, as I am having a hard time
finding a cam for my 1.9, that's efficient, without the computer chip.

You ought to slap a performance pipe on her too!
I put a round turbo muffler, in place of the $295.00 stock unit, and it
growls real neat, kind of like an old Porsche!

Anyway good luck in you endeavor.
