Well I bought this kit off a friend and have a few questions on some holes it has open. I pretty much got everything figured out just don't know what these openings are for or were do they go to. Can anyone help? I circled them in red on the images. This will be going on a 2006 Silverado 5.3

The Full kit




On the WasteGate



On the Blow-Off Valve




On the pipe that runs to the Throttle body

 

Wastegate port goes to a pressure only source, like the turbo compressor outlet. Some will say a pressure/vacuum port also work, depends on who you ask.

BOV port goes to boost/vacuum port, probably the top one. Not sure what the bottom one goes to. Atmosphere?

BOV exit just goes to atmosphere.

The threaded bung in the pipe is probably for a intake air temp sensor, or maybe meth injection? Not sure on that one.

 

How would you connect them to the Vacuum tho?

 

You can get vacuum/pressure from the manifold. I'm going to tap into the brake booster line, but you can also use the EVAP port if you have gotten rid of you EVAP system.

 

Or break off the tab on the passenger side around runner #6 bout half way up..
Most of my stuff is run from there, my wastegate is run to my turbo housing.

 

any port on the intake manifold will work, there is one with a tab on it from the factory that just has to be torn off to use. I also use the top port where the pcv valve is normally vented to. The bung in your cold pipes is to thread an IAT sensor in, run the two wires to the IAT wires included in the maf harness and splice in there.

 

Can you please post some pictures so I get an idea of what your talking about. Thanks

 

yep yep.. gimme a few min.. i get off work in 9 minutes..

 

Alright, thanks. I also have a AEM TruBoost gauge and it has a hose that I thought it might go there to read turbo pressure but dont know

 

Boost gauge also goes to the manifold, you can use the same port as the BOV with a tee fitting or something.
