Ok I've seen plenty of posts on this...but no one really answers it. When you remove the acv you lose the vaccum nipple for the pressure sensor. Can I just tee this into the line that runs to the bov? Lastly, are there any ports on the car that would supply just a positive pressure or just a vaccum signal? Just want to make sure that there aren't any check valves or anything when I start removing the emissions bs. Thanks guys.

 

86-88 I gather. The 89-91 has it on the Intake plenum.

Any vac source should be fine.

NA or TII? I remember it being on the intake manifold on my GXL. I haven't gotten around to ditching the smog on my TII yet...

 

Yeah it's an 88 TII. I would think the nipple off the pass side of the intake manifold will work for the pressure signal...right now that nipple just supplies the vaccum/boost level to the BOV. Also, I think there are 3 vaccum ports off the throttle body. What do all those lines run to. Eventually I'm going to remove the rats nest and I need to figure out where I can run what. Obviously I'll need some kind of vaccum boost signal for the fuel pressure reg, bov, pressure sensor and wastegate. Am I forgetting anything? What about the *PCV* type stuff. Later.
