Newly established German tuner Prototyp Production is presenting its first upgrade kit for the Porsche 911 Turbo S (991 generation). On the outside, there’s not much going on as the aftermarket specialists only changed the stock wheels and replaced them with their own set of 21-inch NEMESIS Limited Edition 50 alloys which are shod in 245/30 ZR21 front and 305/25 ZR21 rear Michelin Pilot Super Sport tires. There’s also a new stainless steel exhaust system with 200 cell sports cats and two valve while inside the cabin they used matte carbon accents.
Most of the work has been implemented in the engine bay where the direct-injected 3.8-liter 6-cylinder turbocharged gasoline engine has been tuned to develop 604 PS and 820 Nm so it’s now considerably more powerful than the stock version which delivers 560 PS and 700 Nm (750 Nm when overboost is activated).
