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 but also come in the Pulsar GTI-R and bluebird. Many Americans are now opting to put this engine in their Nissan 240SXs, not satisfied with the 155 horsepower produced from the stock KA24 engine. Engine swaps are becoming commonplace for performance shops, and aftermarket parts for the Japanese engine are easily available in the US.

As the sport of drifiting becomes more popular in America, the demand for these SR20DET engines increases. While found easily in Japanese junk yards just a few years ago, these engines are becoming harder and harder to get ahold of.

The breakdown of the engine code is as follows:

• SR - Engine Code
• 20 - 2.0 Litres
• D - Dual Overhead Cam
• E - Electronic Fuel Injection
• T - Turbocharged
