Nissan has announced a series of updates for the 2013 GT-R, aimed at improved engine response, stability at high speeds and ride quality.
Nissan engineers fitted the 550-hp 3.8-liter twin-turbo engine with new injectors, while a new relief valve was added to the turbocharger to supress the loss of boost. Both modifications are aimed at improving engine response in both the mid- and upper-rpm rev range. Also, a new oil pan baffle was mounted to help maintain pressure and reduce friction.
Nissan tuned the suspension as well, with modifications made to the front dampers, springs and anti-roll bar lowering the car’s center of gravity. The front suspension received cam bolts in order to improve camber accuracy and stability during hard cornering.
Additional reinforcements around the cabin added by the engineers are said to increase body rigidity and improve suspension control. According to Nissan, these changes have been applied based on feedback acquired from competing in the 24-Hours of Nürburgring race earlier this year.
In addition to performance upgrades, the GT-R will be offered with a Premium Edition version that features rich Semi-Aniline leather and custom-colored interior as fashonable interior package, further enhancing the sense of quality within the cabin.
