NISSAN 4.5 VK45DE

The 4.5 L (4494 cc) VK45DE was introduced in 2002 and is built in Yokohama, Japan. Bore is 93 mm (3.7 in) and stroke is 82.7 mm (3.26 in). Output is 340 hp (254 kW) at 6400 rpm with 333 lb·ft (451 Nm) of torque at 4000 rpm. Redline is at 6600 rpm. It has an aluminum engine block and aluminum DOHC cylinder heads. It uses SFI, has 4 valves per cylinder with VVT and features forged steel connecting rods, 4 one-piece cast camshafts, and an unusual variable-flow induction system optimizes airflow for low- and high-speed operation and low-friction molybdenum-coated pistons and microfinished crankshaft. Motorsport A flat-plane crankshaft version of the VK45DE was used by Nismo for Super GT races with the Nissan GT-R instead of using the GT-R's VR38DETT twin-turbo V6 engine.[1] The VK45DE was previously used in Nissan's 350Z Super GT car in 2007, replacing the previous VQ30DETT used in that car. In race trim, the Super GT VK45DE produces 500 PS (490 hp) and 52 kg·m (510 N·m; 380 lbf·ft) of torque.[2] The engine idles at around 3500 RPM and is restricted to the above specified power output. Without such restrictions, the engine is reputedly capable of producing nearly 800 PS (790 hp).[3] Nismo reasons that by using the engine, they eliminate turbo-lag, save weight and generally prefer the torque curve of the atmospheric V8.[WIKI]
