You probably should wrap your power steering hose, the heat from the turbo will melt it.
I am no longer using the original power steering box.
I installed a rack & pinion set-up.
But if I were to still use the stock steering box, I would definitely use a turbo blanket & use lots of heat reflecting tape products.
