The SR20DET, like with the outgoing CA18DET, was a turbocharged intercooled engine in top form. It was Nissan's popular four-cylinder 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, Nissan NX Coupe and the Nissan Bluebird. It replaced the CA18DE and CA18DET engines that originally powered the Silvia and 180SX from the S12-chassis and prior. The previous CA18DET was deemed too expensive to produce (due to its cast-iron block) and no longer met Japanese emission standards, and so was replaced with the SR20DET.
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 SOHCKA24E for earlier models, or the DOHCKA24DE for later models. Both are naturally aspirated engines and are much less-powerful than the CA18DET and SR20DET engines, producing 140 hp (100 kW) and 155 hp (116 kW) respectively. SR20DET engine swaps are becoming more commonplace due to the aftermarket forced induction options available for the SR20DET. There are many tuning shops out there that specialized only in SR20DET swaps.
The Garrett T25G turbo used on most SR20DET engines.
The SR20DET was first introduced in the U12 Nissan Bluebird 2000SSS ATTESA Limited in a transverse-mounted front-wheel drive/four-wheel drive form in October 1989. The first revisions of the rear-wheel drive S13 Nissan Silvia and Nissan 180SX produced in 1991 were built with a longitudinally-mounted SR20DET. Others had the naturally aspirated SR20DE. The engine then went on to be used in a number of Nissan vehicles, including the Nissan Avenir in 1995, the Nissan R'nessa in 1997 and the Nissan Liberty in 1999. The SR20DET (along with the naturally-aspirated SR20DE) was retired in most Nissan vehicles in August 2002 (including the S15 Nissan Silvia), and were replaced with the QR20DE engine in most applications.
Out of all the Nissan models produced with the SR20DET engine, the Silvia was the longest-running model to use it, starting with the S13 series in 1991 and ending with the S15 series in 2002. The S14 and S15 series used a bigger turbocharger than the S13 series.

Twin-turbo modifications
While all factory manufactured SR20DET's featured only a single turbo unit, some aftermarket tuners have engineered working twin-turbo configurations. One such kit produced by ENDLESS Japan in 2008 featured two GReddy TD05-16G turbines in parallel. These were mounted on a custom exhaust manifold and downpipe, and required heavy modifications to the engine bay to fit correctly. This twin-turbo setup achieved its peak power at 2.2 bar between 5,500–6,000 RPM, and costs ¥300,000.[3]
Applications
The 1999 Nissan Silvia Spec-R (S15) is powered by the SR20DET.
The SR20DET is used in a number of Nissan vehicles produced from 1989 to 2002, including the Nissan Silvia line of compact sports cars. Below is a list of these.
