96099, Plugged Vac line and TB port
Posted by Jacque766, Jul-07-06 07:07 PM
The EVAP line is T'd off at another location. So what can I use the TB vac port for? Can I plug the BOV or wastegate into this?


And I found a line plugged that connects to the 2nd hard line in between the fuel lines. To clarify there are 5 hard lines under the car going back towards the fuel tank. 2 are brakes and then there are two bigger lines (fuel) and one smaller one in between the two fuel lines. the second line seems to go back to the EVAP stuff in the rear. but in the engine bay it was just plugged off. should there be a vac source on this?


Also can i T' off the PCV line just before the mani for the WG?

You can plug the BOV into this. but as above said just run the line for the wastegate from the turbo.

IM lost on the wastegate comment.


Its a Tial 40mm. Mounts to manifold and then the exit pipe goes down into the down pipe. But my question is what connects to the two barb fittings?

Is the top one vac? and bottom something else or do they both need to have a vac source?

Or is one suppost to go to my Boost contoller?

How is it suppost to connect to the turbo?

Ok, i just learned something from search!


So let me run this by again...

vac port from mani.... line straight to BOV.

For wastegate vac port from mani then T" it off one side goes to BC and then from BC to the top of the wastegate, the other line from the T" goes straight to the bottom fitting of the wastegate correct?


now i also read that the vac source for the wastegate should go before the TB on the Tial site? so do i just tap it into the intake piping?

i originally thought everyone was just using a vac port on the mani?


but what is the difference?

What? There is no fitting on the turbo at all. How can you run a line from the wastegate or BC to the Turbo?

Does it help if I say I have an apexi ACV-R...dosnt that control my boost?


And what about the vac source....before or after the TB? Why does manual say before?
