Cobra N+ offers a 550-hp Nissan GT-R, 620-hp upgrade in the works

Cobra N+ is known for exclusively customizing and tuning Nissan automobiles, so it’s only fair that the tuning firm takes a shot at the new (now) 485-hp twin-turbo V6 Nissan GT-R. The Cobra N+ engineers are already hard work at the first tuning stage for the GT-R - which means there is more to come from Cobra N+ in the future.

The first stage is projected to deliver a total of 550-hp with a peak torque of 501 lb-ft. Engineers will be reprogramming the ECU, boosting pressure by 0.15 bar and modifying the air intake with sport air filters to achieve the upgrade. A Cobra N+ stainless-steel high-performance exhaust system with metal catalysts will also be fitted to the GT-R. 0 to 62 mph comes in 3.5 seconds like the production GT-R but top speed has been increased from 193 mph to 199 mph. Is it worth it? Probably not if you ask us. Nonetheless, Cobra N+ assures us that plans exist for a 620-hp in the near future.

Cobra N+ will also offers a sportier coil-over suspension, 21-inch light-alloy wheels, upgraded 8-piston brake calipers with 405-mm brake discs on the front axle, and a visually appealing aerodynamic body kit. Inside, buyers can opt for luxurious interior with sewn upholstery for the seats and doors made from a combination of leather and Alcantara or go for a more racing look with light carbon-fiber racing seats, six-point seat belts and a roll cage.

Cobra N+’s tuning program for the GT-R will be available for the European market in spring of 2009.
