The Nismo-tuned GT-R makes use of an uprated twin-turbo V6 3.8-liter engine which now develops 595 HP (438 kW) and 480 lb-ft (650 Nm), up from the previous 545 HP (401 kW) and 463 lb-ft (627 Nm) of torque. The increased output was possible after revising the intake and exhaust systems, as well as by installing bigger turbochargers derived from the GT3-spec model and modifying the ignition timing. Nissan mentions it would have been possible to squeeze additional power from the engine but at the risk of damaging the gearbox.
The Nissan GT-R Nismo sits on 20-inch alloy wheels wrapped around in 255/40RF-20 run-flat Dunlop SP Sport Maxx GT 600 DSST tires which provide more grip than before. The vehicle will be available with an optional track package which was capable of lapping the Nürburgring in 7:08.69 at the end of September when it was driven by Michael Krumm, an ex FIA GT1 champion.
This optional kit will encompass several carbon fiber body parts, along with a front splitter and a massive rear spoiler. Those carbon fiber bits and pieces will shave off a significant 143 lbs (64.8 kg) from the car's curb weight. In addition, the package will also encompass various chassis tweaks, manually-adjustable Öhlins shocks and different springs with a lighter rate.
Nismo started work on the V6 3.8-liter twin-turbo engine and raised its output to 600 HP (441 kW) and 652 Nm (481 lb-ft) of torque. The additional power was obtained after installing new high-flow turbochargers with a larger diameter which were derived from the GT3-spec car. In addition, Nismo's engineers optimized the ignition timing control for each of the six cylinders and they also improved the fuel pump combustion.
The GT-R Nismo has gained new springs and custom Bilstein dampers at the front and rear suspension which have been tweaked to provide the supercar with better grip and handling. The driver will have the possibility of selecting from one of the three suspension modes: Comfort, Normal and R, with the latter being developed specifically for track use.
It rides on exclusive Dunlop tires measuring 255/40 ZRF20 front and 285/35 ZRF20 rear and benefits from a hollow rear anti-roll bar. The Nissan GT-R Nismo also comes with new links fitted to the front double wishbone suspension and has received large high-rigidity bolts for increasing stiffness around the wheel hub attachment area.
The vehicle has gained an aerodynamic exterior kit which includes a carbon fiber rear spoiler, a wider front bumper and an elongated yet tapered rear bumper. The GT-R Nismo will be available with the following body paint schemes: Brilliant White Pearl, Meteor Flake Pearl Black, Ultimate Metallic Silver and Vibrant Red which will be matched to six-spoke black alloy wheels derived from the firm's GT500 racecar.
Inside the cabin there is red stitching on the center console, seats and door trim, along with an Alcantara-wrapped three-spoke steering wheel. There are also new ergonomically-sculpted Recaro seats with carbon fiber backing and a carbon-like look for the dials.
The teaser video released last week with the name “1” was actually a reference to title of the fastest volume production car around the Nürburgring as the vehicle was able to lap the German circuit in 7:08.679. However, the GT-R Nismo in question came with "track options" which we talked about yesterday but in the official press release there's no mentioning of this kit.
The 2014 Nissan GT-R Nismo is scheduled to go on sale at home in Japan next February, while United States and Europe will get it several months later.
