Porsche Crest Vacuum port question.....EFI

Hey guys,

I am kind of a newbie with this aspect of the car so I need help. I need to know how many vacuum ports I need and what sizes should be acceptable.

Please tell me if Im missing anything here.

1. Brake booster
2. Waste gate
3. ECM (for internal MAP sensor)
4. Blow off valve
5. Fuel pressure regulator

Last, is it possible to tap the manifold for one large vacuum hose to go to a remote mounted vacuum manifold that has all the required fittings on it? I would like to do it this way to keep my custom manifold as clean as possible.

Thank you for any thoughts here.
