Turbo coolant feed source

I think that's a very low pressure area of the cooling system, so it'll be a very inefficient system (for the turbo coolant flow).

I think Mazda desgined their system so that the turbo coolant feed line was as short as possible?

It doesn't matter if the coolant is a little over 200F versus maybe maybe 50F degrees cooler...
The turbo (CHRA) gets a LOT hotter than that.
The reason to run coolant through the turbo is to keep the oil from coking in the center.
We're talking preventing the oil from hitting 300F+.
