First off: yes, I've searched and read every post I could find, but most have broken links where people posted helpful pics. Second: I'm using these two write ups: http://howto.globalvicinity.com/gv_w...i=44&co=1&vi=1 & http://homepage.mac.com/carldavis/intake.html

I'm about to be past the point of no return with an S5 intake conversion on my 88 NA, and I wanted to see if anyone could answer a few technical questions before I tear everything apart.

Which of the hoses on the dynamic chamber are vacuum, and which are metered air (before throttle plates)? I know the Pressure Reg uses vacuum, and the oil injectors get metered air, but what about the purge control, ACV (dark green) & egr/relief/switching lines? I will be keeping all emissions except the egr, by the way since I live in CA.

Then for the S5 manifold, I know the top (blue) hose coming off the rear of the dynamic chamber is metered air, but are the yellow and pink ones vacuum? The S4 has 2 lines going to the purge control valve, so I can tell either the yellow or pink hose (on the S5) must connect to it as well before being split into other systems, but which one? Oh and disregard the circled areas, this is the way I found this image.

So if anyone knows off-hand which is which lemme know, otherwise here are some nice color coded diagrams (from old posts) for anyone that needs 'em.

Well, here's what little I have from one of those sites that's no longer around. Two of the attached pics are from the vacuum/metered air routing one of those guys did without a hardlines/emissions.

And here's my way, which kept all the emissions stuff. I don't remember if I posted this somewhere else, but here it is:



Also, here's a write up on using RPM switches to control the 6PI/VDI systems: https://www.rx7club.com/2nd-generati...itches-907824/
