coolant lines for turbo

[Big Turbo Scott]

Hey everyone, Im thinking of rerouting my coolant lines for the turbo. It appears that most everyone uses the TB coolant lines which I believe is on the suction side of the water pump. Has anyone tapped into the pressure side to get the lowest possible coolant temp? Does it matter? At what temp does the coolant have to be before it causes harm to the turbo? Any benefit to running cooler water to the turbo? Any thoughts on this matter are appreciated!

The coolant will never cause harm to the turbo even at 300 degrees F. when the motor is melting.

Turbo bearings and housings are even hotter.

The cooler the better I think, well unless the iron housings crack.

Doubt that's gonna happen though.

I use the heater feed and return, lots more flow.

No clue if it matters it was just easier for me to plumb.

I was considering tapping into the water pump and using the heater hose as the return. Im using the lines with the banjo fittings so flow would be relative to a 3/8 line. Does the turbo need the additional volume provided by the larger lines?
