Cobra Technology has released a handful of images and info on its tuned Nissan GT-R, dubbed the Cobra N+ Tuning Concept. There's a full press release after the jump, but the important bits are this: When equipped with the Stage One package, output rises to 550 hp while torque grows to 500 lb-ft. So equipped, Cobra says its fettled GT-R will run to 62 mph in under 3.5 seconds and max out at 199 mph. If that isn't enough, a planned race performance version is expected to pump out 620 hp and 590 lb-ft of torque.
To get the extra power, Cobra reprograms the ECU, ups the boost pressure by 0.15 bar and modifies the air intake. A new free-flowing stainless-steel exhaust system is also in the works and the upgrades aren't just restricted to the engine bay. Cobra has aworked its magic on the suspension, wheels and brakes. Three-piece, 21-inch, lightweight rollers make room for eight-piston brake calipers and 15.9-inch discs up front, and the coil-over suspension features adjustable ride height and damper rates.
The interior gets two options: luxurious Alcantara and leather, or racing-spec carbon fiber seats and a roll cage. Exterior changes include a front fascia claimed to reduce lift and improve cooling, new rocker panels, and a reworked rump with an integrated diffuser and a larger wing. Personally, we'd pass on the Speed and Stripes decal kit (it's got a whiff of John Player Special livery gone awry) and go stealth instead.
The Cobra N+ tuning program will be available when the Nissan GT-R reaches the European market in the spring of 2009. We're not sure we'd want to mess with Nissan's sophisticated suspension setup, but the extra power, body kit, interior upgrades, along with updated wheels and brakes, look rather tasty.
