Unique Infiniti M45 Shares Drifting Experience

Whatever some enthusiasts may think of drifting as a motorsport, the fact is that it has grown to be a huge attraction for spectators and the build quality of the cars is on a level of the highest caliber. One unique drift car that has made waves is not actually used in drifting competitions but is instead a demo car, able to seat 3 passengers in what should be a unique and memorable experience. This car is the brainchild of 2009 Drift Champion Chris Forsberg, who conveived of the project car at the end of the 2010 season. Starting with an Infiniti M45 luxury sedan, Forsberg and his crew put the car on a diet by stripping the interior and installing a Seibon carbon fiber hood and trunk lid. The chassis was also strengthened and a unique roll cage was added, which took into account the passengers who would eventually be along for the ride. The whole package was then were painted white, including the carbon fiber components. Four Recaro racing seats were then installed to accommodate driver and passengers.

Obviously, a change in power was needed so Forsberg installed the engine and transmission setup from his 2009 Championship season 350Z, which is a Nissan VK56 V8 engine that was hijacked from a Nissan Titan. Surprisingly, the 5.6-liter VK56 is practically stock with the exception of Bosch 680 cc/min injectors and 256-degree S2 camshafts and upgraded valve springs from Jim Wolf Technology. The four cams in this engine feature 256-degrees of duration and .430" lift (stock is 232-degrees with .346" lift). The increased duration camshafts resulted in the powerband of the VK56 engine moving higher up the RPM range. In drifting, the driver is constantly running the engine near redline and moving the powerband up the rev range certainly fits the requirements of that particular driving style. A custom Hogan's Racing sheetmetal intake manifold tops off this otherwise stock powerplant. The reverse-mounted manifold (throttle body towards rear of the vehicle) uses dual Holley 52mm throttle bodies. A Walbro pump, Aeromotive pressure regulator and a Chevy LS1 coil pack make up the ancilliaries. Managing the fuel and ignition timing events is a BigStuff3 GEN3 PRO SEFI engine management system. This system is fully-sequential and offers full data logging capability. Horsepower calculations place the engine’s output at at least 360 horsepower at the rear wheels.

Completing the setup are DG-5 coilovers as used in the competition 350Z working with Tanabe 18X11 wheels shod with Hankook RS-3′s tires. This car is obviously a huge cost for the team but it is a measure of Forsberg’s generosity that he chose to build the car so that the drifting experience could be shared with the lucky few who get chosen to ride this unique car.
