| Predecessor | Nissan VH |
The VK engine (formerly known as the ZH) is a V8 piston engine from Nissan. It is an aluminum DOHC 4-valve design.
The VK56 engine was originally based on Nissan's VQ V6 rather than the VH V8 used in previous Q45/Cima models. Changes include: a variable polymer intake manifold, newly designed heads, and a larger drive by wire throttle chamber. The intake manifold directs air through different paths at different engine speeds to optimise low-end torque or high-end horsepower.

VK45DE
VK45DE
The 4,494 cc (4.5 L; 274.2 cu in) VK45DE was introduced in 2002 and is built in Yokohama, Japan. Bore and stroke is 93 mm × 82.7 mm (3.66 in × 3.26 in). Output is 340 hp (254 kW; 345 PS) at 6400 rpm with 46 kg⋅m (451 N⋅m; 333 lbf⋅ft) 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 (368 kW; 493 hp) and 52 kg⋅m (510 N⋅m; 376 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 (588 kW; 789 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.

VK45DD
The VK45DD is a 4,494 cc (4.5 L; 274.2 cu in) V8 engine that is very similar to the VK45DE but adds a direct injection fuel system. This was Nissan's first V8 with direct injection (NEO-Di). It officially produces 280 PS (206 kW; 276 hp) @ 6000 rpm and 46 kg⋅m (451 N⋅m; 333 lbf⋅ft) @ 3600 rpm, but it has unofficially over 300 PS (221 kW; 296 hp). It has a compression ratio of 11.0:1, and a bore and stroke of 93 mm × 82.7 mm (3.66 in × 3.26 in).

It has aluminum-alloy block and heads and low-friction molybdenum-coated pistons. The valvetrain is a dual overhead cam (DOHC) design with a continuously variable valve timing control system (CVTCS) on the intake valves. It also has 4 valves per cylinder with micro-finished camshafts and ductile iron cylinder liners for increased durability.
Motorsport
Nismo also uses the VK56DE for FIA GT1 racing. In race trim, it produces 600 hp (447 kW) and 650 N⋅m (479 lbf⋅ft) of torque.[5]
The Nissan Motorsport VK56DE was launched in Australia for the V8 Supercars Championship in 2013 by Kelly Racing in Melbourne. The engine has been reduced in capacity to 4,990 cc (5.0 L; 304.5 cu in) to fit the V8 Supercars regulations. It has a bore and stroke of 102.69 mm × 75.31 mm (4.04 in × 2.96 in). It will be fitted to a Nissan Altima version of the V8 Supercars "Car of the Future" specification that will compete from 2013 onwards.[6]
