What have other people found is the best place for boost (for the guage) and vacuum lines (for the BOV and the wastegate) please be detailed. Thanks!
 
The BOV should be on a dedicated line. I use the nipple on top of the manifold for it. The boost gauge isn't that important. Wastegate, I go off the turbo housing, but I also have a boost controller (without a boost controller, you'll "lower" your boost going off the turbo housing rather than off the manifold).
 
The best place is right off the intake manifold where the line for the fuel pressure regulator or the cruise control get their vaccum source.

are you running a manual boost controller? and you have it on the port off of the intake housing. easy enough. that's what i figured. if i use a boost controller you just come off the turbo housing, then to the boost controller, then to the wastegate, correct? Arn't wastegates adjustable? Im going to use a DSM T25. anyone know if it is? or am i going to have to run a boost controller?

Hey everyone.. I'm putting in a 3 pod gage holder on the dash of me 08 3 sport HB (It's going to look awesome) and I need some help. I go a got a volt, water and vacuum gage for starters. My question is, has anyone had to go through the firewall from the inside of the cabin and where did you drill if you did.. The other question is, where is a good place to put my "T" for the vacuum gage?? I can't find any rubber hoses to splice into.. If anyone has any help please let me know... Thnaks everybody!!!
 
Holy revival of old threads..

Most of us around here are Protege guys, but try posting in the Mazda3 Performance section, they'll know.
 
The cars come with pre existing holes in the firewall in more then one place were wire, hoses etc come into the cab. just run ur wires through those holes
