NISSAN ENGINE LDV A15 RB20 LD23The Nissan A engine design is a refined, quiet and durable gasoline engine. It appears to be a modern replacement of the earlier iron-headed Nissan E engine and is of similar dimensions. The 1960s E series was an all-new design from newly acquired Aichi Kokuki, and integrated Nissan's improvements to the BMC A-Series engine design of the 1950s (Nissan was a licensee of Austin Motor Company technology), mainly comprising changing the camshaft from the left side to the right side so removing the intrusion of the pushrods from the porting allowing 8 individual ports instead of 5 originally, and moving the oil pump from the rear of the camshaft to the right side of the block. As production continued, 1974 and newer A-series engines had different block castings, with relocated motor mount bosses..
