Thinking: Single Turbo Oil Drainage
So I was thinking, "why not use both oil drains on the engine" for the single turbo, as used with the stock twins.
Just put a Y from the turbo out to a line for each of the iron plates.
Wouldn't this help with drainage and therefore less blowby (with properly installed catch can)?

One because it is not recommended to use an oil restrictor on the turbo I am going to use (GT35R).
Two, it's an extra ss line that takes 10 minutes to put together.
Three, you have more flow out capacity.
I don't know for sure, that is WHY I was asking.

Boy is my math off.. Oh well! I run -12 because it slipped over the stock return with the end flange cut-off.. I just figured it sounded right! Thanks for the clarification.

How would running a (1) -10 line from the bottom of a turbo to a -10 Y to split into (2) -10 lines be more restrictive? Using a correct type of Y connector such as:
I already have one of these for the fuel lines, and there is no way this is restrictive.

I was thinking of doing this but my manifold would be in the way also and would worried about the path not being at enough of a decline. My -12 seems to be doing the job.

I've seen that -10/-12 arguement on here quite a few times...i want to clear it up. The -10 lines DO NOT fit over the stock oil return line. I bought both and just sold the -10 on ebay. It didn't fit...no way no how, not if you bench 500 lbs and force that sucker. Its a -12.

I've posted photos of the -AN fittings and line I used to fab up lines for my car and several others. Remember, the turbo drain line is gravity return and must be w/o kinks, loops, fitting restrictions, etc. that would inhibit gravity flow. I use -3 for oil feed line. And, as someone mentioned, it's inadviseable to use a restrictor.
I know I've been vocal on this topic; I've seen several turbos ruined due to poor oil line fabrication and routing performed by "professional experts" that resulted a huge amount of out-of-pocket expense and down-time and aggravation for the customer.
