custom intake manifold, what can i get rid of?
 

I'd like to start building a new upper intake manifold for my '94 TT. I'd like to run as few vacuum lines as possible as well as sensors. The stock UIM is full of both and I'm wondering what I can remove.
I've searched for hours on the topic but all I can find are pics of other custom manifolds...nothing that specifies whats exactly needed to run the car. (idle adjustment is no big deal)
Any info would be greatly appreciated.
