Stick with the 5W-30, and if you want better turbo protection, especially if you are not adding water cooling or continued oil circulation after shut-off, go full synthetic.
Biggest problem in turbos is shutting them off when hot, cooking the oil in them. Worse yet is restarting after 2 or 3 minutes when the bearings are expanded from the heat and end up spinning or damaged.
