Just installed my red billet oil catch on Saturday. Hoses are all installed, need to work on a permanent bracketing arrangement, right now its wire-tied temporarily to keep it from bouncing around too much. Got mine on ebay for $32, can is excellent quality but nothing except the mounting bracket was any good as far as accessory items, spent $20 at Advance Auto to get the 5/8 to 3/4 copper hose/pipe adapter (the adapter is copper, that is) and a bag of 6' heater hose - 3/4" and S/S aircraft hose clamps. Total install time about 1/2 hour, gonna be a bit more to figure out the bracketing. To a degree you do get what you pay for, obviously in this case all the money went into the can itself, which is fine with me, rather have a good can and just swap out the crap anciillary parts. Yes, I know the $200 ones have wire-mesh oil "fences" inside but I do have a limited budget and still need to do the FMIC. Can always upgrade later if I find that this thing is as effective as some other people are claiming. I am curious to see how much oil gets bypassed.
Second, beware of using heater hose for the catch can connections, that hose is susceptible to breakdown from the vapors and liquids passing through them. They won't breakdown overnight, but they will breakdown. Now having said that, at their price you can replace then every two years or less and come out ahead if you don't mind all the extra work. But who knows what those hoses will introduce into your system.

When deleting or blocking off the first PCV line, you must install an oil catch can in the second line or all the oil and crankcase fumes will be drawn through the turbocharger.

Dave, excellent clarification. I was pondering an answer but knew in my head what you said but for some reason when I started typing it in it came out different.
I'm glad I held off a bit..
BTW Tim - there are no stupid questions. Questions are the base to knowledge.

You also need to go into your signature and state what year and model your car is so that if you have any issues we can readily identify what gen. you have.

Wouldn't bother me.
It's on order so it's as good as yours.
I can't answer your question though for the 2011.
I'm pretty sure BSH makes one but not sure if you need the boost
tap as well. Somebody will jump in and answer it.
I buy alot of my stuff from www.waymotorworks.com
The owner/mechanic is Wayland (Way) and he's very knowledgable and helpful. He is another good source for info. I see on his web site he has the BSH cans for 2011's but they aren't going to be in until July but he's taking pre-orders.
You can call or email him and he can surely answer your question.
They are definietly a good investment. I wouldn't call it a mod but a necessity with these DI engines.

2011 and newer MINI Cooper S models, have N18 engines and have a single PCV hose, from the head cover to the turbocharger. The other PCV hose was replaced with four passages in the head from the head cover, and PCV valve, to the intake ports in the newly designed head. The JCW MINIs still have the N14 engine.
So far, I have not read any complaints about carbon build up on the MINIs with N18 engines.
MINIs with the N18 engine have variable valve timing on both the exhaust and intake cams (VANOS) instead of only on the intake as on the N14 engines, this is why there was a redesign of the head for the N18 engine. That, and a new ECU with different programming may have solved the problem with carbon build up on 2011 and later MINI Cooper S cars, only time will tell.

I think that an Oil Catch Can is unnecessary on 2011+ MINIs.
I know someone who recently installed a Helix step-core intercooler in his 2011 Cooper S, it had about 10,000 miles on it. There was no oil in the OEM intercooler or in the piping to the intercooler.
