The SR engine is a series of 1.6 to 2.0 L (1,596 to 1,998 cc) straight-four, four-stroke gasoline engines manufactured by Nissan from 1987 to 2007. It was part of a new engine family name PLASMA (Powerful ＆ Economic, Lightweight, Accurate, Silent, Mighty, Advanced).
The SR engine family uses a DOHC 4-valve design, with variable valve timing on select models, and is an all-aluminium design with an aluminium head and block with steel sleeves. All SR engines are chain-driven rather than belt-driven, unlike previous Nissan four-cylinder engines.
The SR engine was designed by Nissan as a replacement of the earlier CA series of engines, which used cast iron blocks and timing belts, and was later replaced by the QG, QR and MR series of engines. It was used in many small to medium Nissan vehicles, including various high-performance turbocharged variants.
