There is no drain for the catch can on your particular setup, right? So if the catch can accumulates oil (which it eventually will, right?) how do you drain it? Remove the lines and dump it?
My setup is super lame right now, just a line routed from the T back, and then one to a "catch-can" (which I think is a spray can?) and a breather filter glued on top. EEEWW.
Also, I see you're running the line off the catch can before the MAF. How would you do this if you were running an Apex'i filter? Make another pipe in front of the MAF so you can run the line into it?

I'd hook up your hoses to the VC and leave it like that, it'll vent itself. If you have a closed system(non-vented can), I'd get the special fittings needed to have it plumbed to the exhaust, after the turbo. The exhaust gases passing the fitting will create a venturi effect and will suck all that stuff out of the head through the can and into the exhaust. You can go before the turbo too but, that means you're sucking all that crap from the head straight into your turbo. Personally I wouldn't want it setup that way...
I run a vented can that has 2 hoses from the VC and a drain, that's plumbed back into the upper oil pan, so anything that does collect in the can goes back into the motor.

Dun need to purchase, you can just bring it to a local weld shop. I think I had pictures of hte setup already. ANyways..... THe drainback is through the head, because the has oil passages to drain back into the upper oil pan, so you don't need any drain back at all. After the turbo or the exhaust is a good source, but its harder to plumb... All stock intakes from Nissan has a opening to be piped from the VC to the intake. Its WAY easier to plumb if you have the drain back system in my pictures with a catch to the intake. After the mafs is best because you don't want that crap to be metered..... Also if you have a catch, it catches about 80% of the crap, so you don't need to worry there is dirt and stuff flying back into the turbo. If you are REALLY anal, stuff steel wool into the can and that catches about 90% of crap.....
