hey, i just thought of something, if i turbo my KA, will i have to re-run the vacuum lines to the intake by the air filter? that way they wouldn’t be pressurized by the turbo, or does it even matter? thanks!
You mean the ones that come off the TB? Leav’em. Of course they’re pressurized, you’re not running in vac anymore you’re running in boost. 
Your boost gauge gets teed off any vac/boost source, and your WG can run anywhere off the charge pipe, the turbo housing itself, or whatever…
