ok, I'm attempting to figure out how to hook up my boost controller while the engine is out so I'll know when it goes in, and possibly replace some vacuum lines with some new silicone lines and remove extrenous lines.

I've been looking over this write up.

as of right now, I have the stock boost solenoids removed.

My basic understanding is that all i have to do is run a vacuum line from the stock waste gate actuators then T and connect them to my EBC solenoid, then run a vacuum line from what the poster of this write up calls "the intercooler piping" to the EBC solenoid. That is my understanding of installing the EBC. But where do the vacuum lines off the recirc valves come into play? or do they not? i'm not sure where those vacuum lines go.

The green dot is the EBC solenoid, the red dots are the turbo waste gate actuators, the black lines are the "inter cooler piping", and then the blue lines are vacuum lines


I was looking at the vacuum line coming off the passenger side waste gate actuator and it plugged into the stock boost solenoid, but also had a T in it ( (this is the T i'm talking about)). Does this T need to be kept and routed somewhere? or can it be eliminated? (according to my basic understanding of the EBC, it should be eliminated and i only need 4 vacuum lines, that eventually turn into 2 that go to the EBC solenoid) Also, where would the short vacuum line run? It's eliminated so that means I need a cap somewhere else.

also, that write up talks about stock turbos needing to put a cap on the intake pipe that is bolted to the turbo, not sure where this is referencing.

 

I see a pic of some vac lines and a childs crayon drawing?

is it manual or electronic?


your vac line goes from a vacuum source to the waste gate actuator. with a manual just put it in line with your waste gate actuator, a manual boost controller is just a one way valve.

{vac source}-----vac line-----{manual controler}-----vac line-----{waste gate actuator)

 

skib - People in the Z32 world don't use manual controllers because we know that their performance is lacking... constantly bleeding boost, boost spiking, boost creeping, etc. All turbochargers perform better with an EBC.


You should know better than to go to 3ZC for tech info.

You only really need one vacuum source to send the signal to the solenoid (one from the plenum if possible, since the air should be nearly regulated there), but you need a T after the solenoid to send the vacuum signal to both turbos.

manifold -> solenoid -> T -> both turbos

And of course, connect the sensor to a vacuum line off the plenum as well.

The vacuum lines for the recirc valves absolutely do not come into play... you never need to touch those during a boost controller install. They get regular old vacuum from the intake system... never has to be involved with the boost controller's vacuum lines.

 

I wasnt sure thats why I asked to start with and just covered the most basic first.
*sigh* I need to get my cheap *** an EBC as well
