Nissan SR20DET

Nissan SR20DET

The SR20DET is part of the SR family of engines from Nissan.

It is a popular engine coming from a variety of Nissan cars, generally the Nissan Silvia and 180SX. It also came in the Pulsar GTI-R and the Nissan Bluebird. This engine replaced the CA18DE and CA18DET that originally powered the Silvia and 180SX. The CA18 was deemed too expensive to produce and no longer met Japanese emission standards, so it was replaced by the SR20. The SR, just like the out-going CA, was a turbocharged intercooled engine in top form. Nissan also produced a cheaper naturally aspirated version called the SR20DE. In the US and Canada, the Silvia and 180SX are both under the 240SX banner. USDM and Canada 240SX's come stock with the SOHC KA24E for earlier models, or the DOHC KA24DE for later models. Both are naturally aspirated engines producing 140 hp (100 kW) and 155 hp (116 kW) respectively. SR20DET engine swaps are becoming more commonplace due to the forced induction aftermarket additions available for the SR20DET. Many shops specialize only in SR20DET swaps.

The breakdown of the engine code is as follows:

• SR - Engine Code Name
• 20 - 2.0 Liter Displacement
• D - Dual Overhead Camshaft
• E - Electronic Fuel Injection
• T - Turbocharged
• The Lack of the letter "D" on some of the engine identifications indicates a SOHC cylinder head.
