Hey guys, I am about to start installing boost here in the near future but I have one small question. Where do I connect all the vacuum lines too? There is one for the BOV and wastegate..am I missing any? I'm not using a boost controller so I don't need one for that. But where do I connect the vacuum lines to?

Thanks,
Elliott

 

BOV after throttle body. Wastegate before throttle body.

There are a few capped off vacuum lines on the intake manifold. Pipe one of those to the bov. Then for the gate, just hook that up anywhere on the intercooler piping. Putting it closer to the turbo is better for faster response, but it doesn't really matter where. Mine is all the way on the intake pipe right before the throttle body.

 

Can you give me a pic of the capped vacuum lines? And for the wastegate does that mean that I have to make a fitting within my piping or what?

 

For the wastegate mine is on the turbo housing see the line running right before the elbow on the turbo..

 

So for the wastegate you have to make your fitting, while for the BOV there are some provided?

 

Yeah ... The line for the wastegate was drilled and tapped with a fitting for the line. For the BOV i used the one thats on the left of the cam gears. Right underneath the reducer coupler on the elbow of the turbo.

 

You want your wastegate line near the turbo. If your going to drill and tap the pipe don't screw the nipple all the way in as it will cause funny reading. Screw it in so it's just a little bit past flush on the inside of the pipe.

Your Bov needs to be on the intake manifold after the throttle body.
