20V MK1 Engine Swap 20v vacuum lines w/ pics

what are these and where do they go? btw i'm running a BT ecu and open velocity stacks.

The top one goes to the airbox. It is part of the idle air I do believe. If running open ITB's you can just put a filter on this and be ok. Same thing with the bottom left one. The rest I will have to look at my car when I get home to tell 100% but most can be capped IIRC.

Can we get a confirmation of this? A detail photo of your setup would be greatly appreciated.

Alright, here are some detail photos of the lines in question on my black top: (I removed the metal bracket that D, E, and F were attached to, to show more detail)

I'm assuming A just gets attached to a simple vacuum line? Or does that one attach to the charcoal canister?

B and C look like they go into the throttle body, so I'm assuming they are vacuum lines and I can attach my brake booster hose to one of them. I have no idea what they were attached to originally.

D attaches to the fuel rail. Where should it go from there?

E and F go underneath and I'm not exactly sure what they attach to, but I'm assuming they are simple vacuum lines. Can they be capped off or must they attach to the intake manifold?

I will take a look at my car and see where I have everything plugged up. Note: E is the fuel return. Don't want to plumb this into the vac lines. lol

I finally got around to everything. With us rolling out our 20v vac line kits here soon I figured now was as good a time as any to look where all these go.

F goes to the charcoal canister (if that is the one that was attached to the bracket)
E is the fuel return
D is optional. You can use this for the A/C idle up though.
C or B goes to your brake booster line. Cap the other one.
A is the Map sensor source.

If anyone is interested we are about to roll out the GB for our 20v vac line kits that will replace ALL the vac lines with silicon hose in either Black, Blue, or Red (also would go nicely with our coolant line kits). The vac line kits will also include detailed pictures and directions on how to hook up all the lines.

Awesome! I had already figured out some of those, but it's good to know where the rest go.

fastrax203 · 08-14-2008, 12:05 AM

A only exists on blacktops it seems, I don't see that anywhere on my engine.

Raptor13x · 08-14-2008, 01:56 AM

^ only the blacktops had the map sensor, the silvertops and prior used an AFM.

kameleon · 08-14-2008, 07:17 AM

Yes "A" only exists on BT engines since they are MAP sensored and not AFM. Also the BT has a port on the #2 ITB below the PCV for the MAP. The other differences lie in the vac lines below the ITB's.... two totally different worlds from ST to BT.
