Nissan NA engine


The Nissan NA family of straight-four engines is a series of engines manufactured by Nissan (Nissan Machinery). It is the replacement of the Z series, on which its design is based, and is mostly used in commercial vehicles due to its use of Liquefied petroleum gas for fuel on engines with a "P" suffix code.
