To everyone saying there isnt a difference between a gatorade bottle and a catch can... There is a difference between a simple catch (gatorade bottle, unbaffled catch can), and an actual baffled Oil/Air separator.
If you run your PCV system with a return to your intake you would want a baffled set up to knock the fine oil mist out of suspension in the air so that it does not go back into the intake of the turbo, and ultimately into the combustion chamber where it can increase the chance of detonation.
Most people do not run a PCV setup like this, but it does yield some benefits, as you will be actively scavenging pressure out of the crank case which can promote better ring sealing and ultimately higher horsepower. If you read up on vacuum pumps or check valves in the downpipes/headers of higher hp applications pulling from the PCV you can see those guys will gain a decent amount of power by running those types of setups.
At any rate, a guy i know ran the Saikou Michi stuff and seemed to be pretty happy with it, seemed to catch a good amount of oil without pushing thru the catch can and back into the intake
Another good looking setup to check out is Radium
