. 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 and 155 hp 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.
