?'s about TII coolant flow & oil cooler flow/relocation...

[nitronatefc]

I am performing a turbo upgrade to an oil-only turbocharger. These questions may be stupid, but they are very important to me. Please don't answer if you don't know. If you do know, please explain your answer in such a way that I believe what you are talking about Motor is S4 TII, no emissions, run on premix

COOLANT
-Is 20mm the proper freeze-plug size for the coolant passages in the motor leading to the LIM?

-Is there a need to install the 2 LIM O-rings with freeze-plugs installed in the motor's coolant passages?

-Is it necessary to block the coolant port on the LIM (which feeds the stock turbo) once freeze-plugs are installed in the motor's coolant passages?

-For this type of upgrade, is it best to have the stock turbo's coolant feed & return, the coolant outlet on the rear iron, and the inlet on the back of the WP housing all blocked off? Is it detrimental to the factory-intended flow path? Would the system's flow benefit from looping any of these ports instead?

OIL COOLER
*Please don't consider clearances, air flow, or custom oil lines in these questions (all in reference to the OEM FC oil cooler):

-Could the cooler be mounted backwards (inlet and outlet towards passenger side of car)?

-Can the cooler be lowered or raised (keeping the mounting angle the same, or more vertical)?

-Can the cooler be inverted (installed upside-down)? This is very important for me to know.

-Can the cooler's inlet and outlet be reversed? Just curious on this one. No need to do it.
