Engine Nissan VK56DE under the hood

Engine Nissan VK56DE

The parent of the VK56DE engine was the VK45DE. Unlike its older relative, this engine acquired a larger cylinder block with a height of 232 mm, due to which the connecting rods were extended to 154.5 mm. The cylinders themselves began to be produced wider by 5 mm, they became 98 mm wide, and a new crankshaft was also installed, which made it possible to increase the piston stroke to 92.8 mm. All the changes led to the fact that the engine began to have a lower Compression ratio and a larger displacement, which was 5.6 liters. The cylinder head is aluminum, the valve timing system on the CVTCS outlet camshafts has become stepless. A chain is used to drive the timing. The result is a motor perfect for pickups and SUVs, taking traction from low revs.
