The perfect highway package, Switzer's P650 is docile enough to cruise along all day, and ready to blitz by traffic as soon as there's an opening. Massive power without compromised drivability is the goal here, and the Switzer-modified VTG turbos deliver, puliing hard all the way to redline and spooling up more quickly than ever the factory VTGs. A great package for heavily street-biased 997.
