You'll want to check out my thread here: The PCV Thread
Basically, you'll want to follow my adaption of the catch can install, except which head is which depends on what your upper intake manifold is (basically just read all of it). You'll want the catch can I mentioned, as well as one off the intake. If your intake is internal (L67) you'll want to block this off and either modify oil cap or drill a point for your intake.
*IMPORTANT* if you don't add baffling under the cap or point you tapped, you WILL suck oil. There's good universal baffles you can install.
The breather port needs to go before turbo, and the vacuum port (see Catch can install) needs to have a one way check valve pointed towards vacuum (this is to prevent positive crankcase pressure when turbo is at high boost).
There's many ways you can do this, but the dual catch can system I described is hands down the most effective and the cleanest turbo setup possible.
Good luck!
