Switzer Performance has announced their new Ultimate Street Edition for the Nissan GT-R. The top American Nissan GT-R tuner has re-engineered the car to deliver exceptional performance without being too over the top to provide a practical driving experience. According to proprietor, Tym Switzer, “For people who want a 1000+ horsepower car that they can drive comfortably every day, to the track or the office or the grocery store, on the highway or in bumper-to-bumper traffic, we’ve built this car.” He continues, “This car idles smoothly. It shifts smoothly. There’s no deafening exhaust or horrific gear whine. There is none of the harshness of most ‘tuner specials’, and we even managed to keep the highway mpg in the 20s.”The Ultimate Street Edition tuning program is comprehensive which sees Switzer-specific pistons, pins, rings, and connecting rods, as well as specially-ground camshafts chosen to optimize the drivability and idle characteristics. There’s also a new pair of upgraded liquid-cooled turbochargers, Switzer’s own intercoolers, transmission cooler and stainless-steel performance exhaust.
