Hi, i'm finishing up the turbo installation and am just doing a bit more research on what to do the with the vac lines. I have my wastegate off positive pressure using the FTG quick tap. I had a few questions regarding where to install a vacuum block and which lines I can remove/plug. I will be using aem ems.
1) After doing research, If i'm understanding correctly, I can remove the two metal piping colored red and green because I'm going aem ems?
2) Do I need the blue connected where it is? Can I install the vacuum block or BOV there, or should I just tap the brake booster line prior to check valve?
3) I'm a bit unsure of the yellow's purpose. Can this be removed?
Ultimately, I just want to have my BOV on a direct source and have a boost gauge tapped in somewhere. If a vacuum block isn't needed for these things, I don't mind not messing with the brake booster line. I was thinking of using the BOV on the blue for the direct source with the boost gauge off the end closer to the block.
Green is a crank case breather same as the blue (blue is pcv tho) youll want to run everything on pcv cause it has a valve that would not allow boost (pressure) into the crank case.
I split things up a little. You might not need this though since I dont see a FPR. Boost gauge and BOV should do well on the PCV tho :thumbsup: cleaner look may be to T into the brake booster line. Idk I never bothered with it though.

Ahhh thank you i'll leave those alone. Any thoughts with blue and green?
you could bypass coolant away from the throttle body (its to mitigate cold weather condensation and freezing in tb) iirc. You would have to look that up and check up on common diy for it. Up to you.

Yo heres how i set mine up. Ap2 here too. I removed the pcv and ran that and the green line to a vented catch can.
The red coolant line i replaced it with a single rubber hose.
Yellow i left alone.
I ran a vacuum block T'ed off the brake booster line for my bov, fpr, boost solenoid, and my boost gauge.
Many ways to do it.
