want.  For all-out power under boost, anything and everything that you can
do to increase mass flow through the motor is good.  The more mass flow,
the more gas is burned, and the more power you get out.

This includes a high rpm cam, but from what I've seen on non-audi turbos
the cam comes late in the game because intake and exhaust plumbing provide 
a much greater benefit with fewer side effects (if any) and at a lower
cost in time and $$.

If you're interested in getting the power on low in the rpm band before
the boost kicks in, you're prolly best off with a stock cam because
factory engineers tend to cheat their designs toward this direction at the
expense of top-end power anyway.

And probably the manifold and turbo- that *could* act just like an
afterburner..  Some rally cars do this on purpose to prevent turbo lag.
