Already pretty impressive and with a never ending list of speed records, the GT-R is today again breaks another record thanks to the Stillen… Yes Japanese tuners are not the only ones that amaze us with our almighty GT-R… Thanks to a huge list of improvements Stillen is announcing a 620hp capable GT-R offering to its future owners a stunning naught to 100 kmh in just 2.9sec…

Here is a rear shot of the Nissan GT-R Fitted with a brand new Ventross body kit. The Ventross Nissan GT-R features the same high quality aerodynamics engineering and construction expected from parent company Vorsteiner. The carbon fiber aero components for the Nissan GT-R is slated for market release on June 1st , 2009.

We've heard about the Nissan GT-R's transmission trouble, but how much abuse will the engine take? Not a 150 shot of NOS on top of 600 wheel HP, that's for sure.

Samurai Speed already found the limits of its transmission, blowing that when they attempted a modified-engine, launch control-on, drag start. Now it appears they've found the limits of the engine: 600 HP at the wheels plus an extra 150 HP worth of Nitrous.

What's next for the GT-R-destroying tuner? All forged internals and 1000 HP. We'll see how long that engine holds together.

It’s confirmed: Nissan is making a return to FIA GT racing. The news came from Nissan Motors Australia Managing Director and CEO Dan Thompson at the press day of the 2009 Melbourne Motor Show.

Nissan will submit the R35 Nissan GT-R into the FIA GT 2010 Championship series while British company Gigawave MotorSports will be teaming up with NISMO on an non-championship entry to check, test and develop the racing GT-R.

The specs on race-ready GT-R haven’t been officially revealed, but there’s a possibility that NISMO will drop the twin-turbo’d V6 in favor of the 4.5-liter VK45D8 V8. Output is estimated to be between 540-590 hp and 450-500 lb-ft of torque, with a curb weight as low as 3,000 pounds.

Japanese tuners HKS and Power Enterprises have revealed rival takes on the art of extracting maximum performance from Nissan’s latest GT-R.

First up is the street-legal GT570 package from HKS, one of Japan’s longer-established tuner firms with a history of GT-R tweakery running back to the 1989 R32 model.

The GT570 Sport Package is a development of an existing GT570 Racing Package designed originally for the track, which includes a new exhaust system, reprogrammed ECU, upgraded plumbing for the turbo and intercooler, a sequential blow-off valve kit, reinforced actuators and new spark plugs. Designed to boost output to 570PS at around 6,600rpm, the Racing Package is not road legal as it fails to meet emissions standards. Hence the arrival of the GT570 Sport Package, which adds a new high-flow stainless steel catalytic converter and upgraded wastegate actuators to bring tailpipe emissions within accepted limits. Parts will be available from HKS stockists later this year for both 2009 and 2010 model GT-Rs..

Meanwhile Power Enterprises has taken a more radical approach to ‘ultimate’ GT-R performance, launching its awesome Quad-Charged version at the recent Tokyo tuning show.

The company claims up to 600hp from the conversion, which basically adds a pair of Rotrex C30-94 superchargers to the existing twin IHI turbocharger installation, as well as high-flow fuel injectors and a massaged ECU.

The two engine-driven compressors are designed to pack greater low-end grunt into the GT-R’s delivery before the turbos get up to speed, apparently for ‘maximum attack’ circuit time trials. Good work!
