Ohio-based Switzer Performance has made its name tuning the Nissan GT-R, but now the company has launched a slightly tamer version. With “just” 1000 hp on tap, the Ultimate Street Edition GT-R is designed to be a 225-mph performance car that owners could conceivably drive every day.
The goal was for this new tuned Nissan GT-R to be tolerable in normal use — Switzer claims the exhaust is relatively quiet except at full throttle, the engine idles smoothly, and gear shifts aren’t overly harsh. That differentiates this model from the more extreme Nissan GT-R packages that the company offers.
“Usable and practical is exactly what we wanted out of the [Ultimate Street Edition cars], and we’ve finally gotten these to the point we want them,” company owner Tym Switzer said in a statement. “There is none of the harshness of most ‘tuner specials’.”
Performance modifications to the Nissan GT-R began with upgrading the twin-turbo 3.8-liter V-6 engine with Switzer-specification pistons, connecting rods, and camshafts. The turbochargers are replaced with liquid-cooled units that produce 30 percent more airflow than the factory ones, and the intercoolers are replaced by larger Monster units alongside Switzer’s front-mounted transmission cooler. Along with a new stainless-steel exhaust and reprogrammed engine computer, Switzer says the powertrain upgrades will produce 1000 hp using premium gasoline.
Though the car produces a claimed 1000 hp, Switzer says it will return better than 20 mpg on the highway. The 2013 Nissan GT-R, by contrast, produces 545 hp and 463 lb-ft of torque, and is EPA-rated for 16/23 mpg (city/highway).
To help keep the ride smooth, Switzer’s Ultimate Street Edition GT-R has lowering springs but the factory adjustable dampers, and new lightweight alloy wheels wearing performance tires. The six-speed dual-clutch transmission also has been worked over by Shepherd Transmission so it can withstand the upgraded engine output, but still remain easy to use in normal driving.
Switzer hasn’t yet revealed a price tag for its Ultimate Street Edition GT-R.
