While installing a turbo kit on the 12+, i would do myself a favor and replace pipe #13 with the 09-11 pipe. They are cheap, I think under $50 from courtesy parts?

This would eliminate the need to block off the forward facing pipe, as it does not have that pipe. Just a little bit cleaner is all. Plus, while it is off, you can cut off and weld shut the throttle coolant barb. To eliminate the other end of the throttle coolant, you can pull out the press-in barb on the aluminum rear coolant outlet housing. A 1/8 NPT tap fits in the hole. Put in a stainless 1/8 plug. This is what I did to eliminate the throttle coolant in my car without doing a messy bypass hose. (bypass hose is also allowing some water to bypass radiator after thermostat is fully open, slightly reducing cooling system efficiency)

Doing it this way would be a clean and easy way to cleanup all the coolant line mess. Tested and proven setup in my car for over 2 years daily driven, even in sub zero weather. For a 09-11 this takes care of it. For the 12+ you still need the fast intentions supplied blockoff plate and whatever fittings to attach oil cooler plate in replacement to stock heat exchanger.
