<VV> Are Turbo Vairs worth having?

[Louis DeRobertis]

I just like showing off all of the shiny parts ;)

Seriously though, is there a middle ground on upgrades to a stock turbo 
setup to get a little more oommph?  I noticed all of the coatings and 
head changes, but does anyone have a recommendation on what to do to 
just get the most out of what's already there?


I also noticed that (or didn't see) any suggestions on the cam if 
you're doing a rebuild of a turbo engine.

Regards,

Lou
