Volks,
I think we all want more power (my primary need) and less head gasket
problems (neither of mine have had any of this, yet it is out there). On
this second point I have no issues so far and my 91 Westy has 144K, 87
101k miles.
I think that doing a "hop up" on the wasserboxer is the solution as
being routinely published on the list here by Robert Lilley, he has done
his homework and apparently has a slick, strong motor that will not
corrode head gaskets. And all for $3K, (I'm sure that was his labor in
there, so add 2K if you farm it out).
Robert claims approx 130 super smooth horses, and no worries of changing
out a) Tranny/Differential Gears or b) All engine electronics (ECU,
sensors, AFM ect. ect.) and b) You can still run to your FLAPS/VW dealer
for parts without any conflicts/confusion from the parts counter about
the "Audi what???" you've got in there.

My $.02 USD's
