Summary
The Nissan P engine is a large overhead valve, inline-six cylinder engine manufactured by Nissan Diesel Motor Co., Ltd. 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.[2] This series of engines were based on the pre-war Type A engine, which was a license built Graham-Paige design.[1]

P edit
The P is a gasoline-powered, overhead valve 4.0 L (3,956 cc) inline six-cylinder[2] 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).[2] 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.
