some more Qs

[thermal]

Turbo shaft does not require too much volume of oil. It just needs enough to keep the journal (or ball) bearing lubricated as it spins. Bigger feed lines means more volume and more fluid volume means more pressure which can overpressurize the bearing area eventually leading to blowing up the shaft seals. I have seen other people even put inline orifice to keep the flow slower.

I highly recommend a steel braided/high temp/petroleum compatible material. I have even seen people use stainless steel tubing, which really did cross my mind to do the same.

If you dont have a turbo timer, sit in your car for at least a minute on idle. What it does is refresh the hot oil from the turbo shaft. It flushes the hot oil out and evenly cools down the lubricating system. The consequences of this can directly affect the life of your turbo. When hot oil is stationary, it has a tendency to "cake" and turn into a sludge. Over time, sludge will start building up and can eventually seize the turbo shaft......
