I circled the red and green lines coming from the front of the S4 dynamic chamber.




The S5 doesn't have these 3 extra ports, where did you guys route these lines to? Will any of the ports on the S5 UIM work for these?

 

Both of those are connected to vacuum. When I did my S5 manifold swap, I ran the red line to the middle nipple on the back of the S5 UIM. The green line I ran to the vacuum hookup the EGR valve used to have on the rat's nest (this basically just taps into the red line's vacuum).

 

One more! Where did you hook up the 4-to-1 vaccum spider? it looks like on the rear runner there is a 6 mm nipple, is that where you guys put it?

 

Run the 4:1 oil injector line to the black plastic intake duct. There is a capped metal line there that is the perfect size, and you need metered air source for it anyway, not vac.

The remaining 2 nipples on the UIM I used for the PCV valve. One is metered air, and one is vac. It uses both. I tee'd the metered air line to the secondary fuel injector bleeds too.

 

This is the hybrid vac diagram I made when I did my manifold swap.

 

Thank you very much!

One more question from your diagram, it shows 3 lines coming from the dynamic chamber, did you use the S5 TB spacer? I only have the S4 and it only has 2 holes for air to go to those 2/3 nipples.
