Use the link that says read before posting, lol. Here's an image NeedCAforS13 drew, this is all you need.



When I rebuild my engine, I plan on removing that vacuum line "rack" for lack of a better word, that runs on the intake manifold.

I would hook up the carbon canister emissions **** myself, improves mileage since when you are not WOT you'll pull fumes to burn from the gas tank. thats where the "blocked off" goes and I think the one he's showing to use for BOV possibly? Would hten of course need to T the BOV from someplace.

Oh man. This is all I need to get the thing actually running? Wow. I've spent three days under and over the car in needless pain trying to get this crap all wired up. Screw that. I just went out to the garage and got this all done in five minutes. I had no clue it was this simple. The only exception I did was taking Biosehn's reccomendation and running the BOV and "blocked off" line to the canister.

Will hooking up the variable intake stuff or anything else aside from on this diagram help emissions any, or is it all pretty negligible and not worth the hassle of doing?
