The GTM turbos are both oil and water cooled. Since the turbos are mounted so low, the coolant will continue to cycle for a little while after shutdown. I still let it idle for a minute or two so the oil doesn't have a chance to coke in the lines and bearings (although modern synthetic oil doesn't do that like it used to).
No real reason for a turbo timer. It doesn't cost anything to sit in the car for a minute after you get where you're going.
