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.{{Cite book |ref = KO07 |last = Ozeki |first = Kazuo |script-title = ja:日本のトラック・バス 1918~1972 |trans-title=Japanese Trucks and Buses 1918-1972 |publisher = Miki Press |year = 2007 |location = Tokyo |language = ja |isbn = 978-4-89522-494-9}}{{rp|page=84}} This series of engines were based on the pre-war Type A engine, which was a license built Graham-Paige design.
