BCS Vacuum lines where too?!?

[kmac714]

ok im pretty sure ik where the vacuum lines go to from the bcs but just to make sure its to the nipple on the intake an then to the wastegate? pictures would be helpful thanks guys

The bottom nipple goes to the T that is connected between the wastegate and the turbo and the top nipple goes to the intake.
You can also just clean the system up and just run a straight hose from the turbo to the wastegate.

^^ like he said. when i first got my car i just went with eliminating it and running straight from the compressor housing to the wastegate. leave you bcs connected to the plug if you do that though.

No disrespect intended Dsmj89 & gstryyder, but just curious if there’s a performance gain or something I missed by leaving the BCS out by running a line only between the waste gate solenoid & compressor.

the benefit is to eliminate vacuum lines. therefore eliminating possible vacuum leaks. also eliminating potential future issues. no real performance gain will be seen.when you do get a manual boost controller you will do it anyways... so why not now. the turbo can regulate its own boost perfectly fine. and it eliminates future problems.

also, you will be running a line between the wastegate actuator and the compressor housing.

by doing this, i believe the stock spring is 7psi, so your boost will be limited to that. with the restrictor removed, you can hit 11 or 12 maybe. but could i just route the compressor side of turbo into the bcs inlet, then that to the wastegate? then plug the other lines?
