Got my rebuilt turbo back so it's time to get moving on this project. Just a few questions about vacuum ports first.

Where do these go?


What is this for? Is it even necessary? I'd really like to eliminate it to make room for a different TB cam.


These went to hard lines and then where do they go?


I'm hoping to cap alot of this crap off so that I can keep it a little cleaner looking but I think I might be forgeting something that needs a vacuum source. There will be no emissions junk either. It will all be removed... No EGR, charcoal canister, etc... However, I may use the AC idle up VSV later.

Those two lines go to the charcoal canister. Just cap 'em off if you aren't using it.

Somebody with a gen2 motor will have to cover the rest...

pic 1 is for your AC idle up system. if u dont plan on having ac, you can cap them.

pic 2 = im not 100% sure what its function is, but i would definetly keep it.

Thanks guys.

Morning bump for picture number two.

I did some checking about pic number two and it seems that it's just another part of the PCV system. I'd almost bet that there is a one way check valve on either the throttle body or VC port that is only open at idle. I'm just going to cap it all off and let the big pcv vent on the drivers side do it's job.
