The SR20DET is a 2.0 L (1,998 cc) straight-four four-stroke gasoline engine that is part of the SR family of engines from Nissan, produced from 1989 to 2002. It is a turbocharged version of the SR20DE engine and is a replacement of the CA18DET engine.
Like with the outgoing CA18DET, the SR20DET was a turbocharged intercooled engine in top form. It was Nissan's popular four-cylinder turbocharged engine fitted into a wide variety of cars, most notably the S13-chassis Nissan Silvia and 180SX. It also came in the Pulsar GTI-R and the Nissan Bluebird.
Both the SR20DE and SR20DET engines replaced the CA18DE and CA18DET engines that originally powered the Silvia and 180SX from the S12-chassis and prior. The previous CA18DE and CA18DET engines were deemed too expensive to produce (due to its cast-iron block) and no longer met Japanese emission standards, and so they were replaced with the SR20DE and SR20DET respectively.
The SR20DET is a popular choice as an engine swap in North American 240SXs (more specifically the USDM and Canadian models), as they use the SOHC KA24E for earlier models, or the DOHC KA24DE for later models. Both are naturally aspirated engines and are often less-powerful than the CA18DET and SR20DET engines, producing about 140 hp (100 kW) and 155 hp (116 kW) respectively. SR20DET engine swaps are becoming more commonplace due to the many aftermarket forced induction options available for the SR20DET. There are many tuning shops around the world that exclusively specialize in SR20DET swaps.
