vacum sources for turbo stuff
 

i was wondering what i should run all my vacum sources from what to where...for my boost gauge, boost controller wastegate, and blow off valve...thank you

I run my boost gauge from a T off the FPR line.

Boost controller goes inline with the wastegate, which I run off the compressor housing of the turbo. If you don't have a fitting on your turbo see below.

My BOV is run from the stock PCV valve line off the intake manifold. You don't need no ------ PCV with a turbo, so make use of that fat port on the intake manifold. T off it and run your wastegate if necessary.

Any vacuum line that's post throttle body with work. Pick one, hook a vacuum port to it, and run all your sources off the vacuum port.

Yea I wouldn't run them all off of one source. Each item you connect to a source reduces the vacuum/pressure it provides, so your BOV or (whatever else) might not function as designed.

I agree. I don't see him needing to tap more than 1 or 2 things into one source though. Boost controller to wastegate and turbo outlet source, BOV to PCV, then the vacuum port for boost gauge etc... to last source.

I guess you covered it in the last post. :1 Eh, it's almost midnight. Shoulda been in bed hours ago.

well thank you all for all the info ...easy enough....i guess

On a vac manifold.... wheres the best place to get vac to supply it?

Re: vacum sources for turbo stuff
 

Go with the PCV.

Brake booster line the 3/8 hose t off it or in one side of the manifold from the intake mani and out the opposite end back to the booster.Vacum manifold is the only way to go otherwise you have some gettho cluster ---- of lines everywhere.

I disagree.
