I have removed whole VacRack and I have kept only the FPR and TwinScroll solenoids. This metal line runs behind the altenator and comes out where the solenoids used to be. Do I need to do anything with it? It's open on both ends right now.
Thanx!

 

dont' need it

it was used for the blow by in the stock application

if you plan on keeping the blow by it's a good line to keep.

 

blow by? Where does the end connect by the turbo normally?

 

it runs to a check valve that is behind the afm on the stock intake

 

Um, that pipe is also brazed to the oil supply line to the turbo.
You really can't cut it off real nicely, and I would suggest you leave it alone.
