Wastegate vacuum line

[Fantas]

76mm, you'll be fine. When I had everything buttoned up and looking at the system it became apparent that I wouldn't be able to tap that portion of the turbo housing; I just ended up welding a fitting nearby.

He has a 76. So he tapped the piping just down stream of the turbo.

Edit. Michael beat me to it lol

Awesome! After reading that thread seems I need to buy more parts lol. So I need two breathers for the PVC valves and rubber cap for the intake?

 

[JeremyH]

Thats the easiest way to do it.

My left hand is now famous! But yeah, you can see where I had no room for the fitting on the housing. There was a little less than 1/4" there.

LOL!

Ur talkin bout your wastegate line? If its that black hose idk I bought gates vacuum line. Oil lines look good, yo are also pushin over 800hp lol

You do not want the signal coming from the compressor because its pre- intercooler. As flow increases the pressure drop across the intercooler will increase and you will get boost "sag". Meaning boost will drop offer high rpm.

You also don't want it from the intake manifold because you could overspin your turbo when boosting at part throttle. Some say that vacuum can damage the diaphram as well, although I've never seen it.

Best place is the cold side charge pipe.

Some nylon hose shit for air compressors I think

 

[S197_smokn]

Wtf? Something's gotta work correctly people put turbos on these cars all the time

 

[Full_Tilt]

Its 'works' in all 3 locations. Manifold, cold side, hot side/compressor. It works best n the cold side charge pipe.

I used a heavy 1/4" ID fuel line for my WG/BOV lines. The wall of the hose is reinforced and a little thicker than normal hose, so it should resist flex/expansion a little better than normal vacuum lines.
