The Nissan P engine is a large overhead valve, inline-six engine manufactured by Nissan from 1959 to 2003 and used in light-duty trucks by Nissan, as well as in the Nissan Patrol. It replaced Nissan's older sidevalve engines with which it shared its dimensions.^: 84 This series of engines were based on the pre-war Type A engine, which was a license built Graham-Paige design.

NAK

Introduced in 1950, the NAK is a 3.7 L (3,670 cc) petrol inline-six engine which produces 75 hp (56 kW; 76 PS). This was directly derived from Nissan's pre-war A engine, a license-built Graham-Paige unit.

P

The P is a gasoline-powered, overhead valve 4.0 L (3,956 cc) inline-six^: 84 with 125 PS (92 kW; 123 hp) at 3,400 rpm initially. Bore and stroke are 85.7 mm × 114.3 mm (3.37 in × 4.50 in).^: 84 Later with 135 PS (99 kW; 133 hp), further modifications in 1965 increased the power to 145 PS (107 kW; 143 hp). Later variants were called P40, reflecting the engine displacement in liters (4.0). A variant especially for fire-fighting duties, with a stronger alternator, an engine block heater, and various other improvements, was called the PF engine.
