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
Origins
The SR20DET was first produced in the U12 Nissan Bluebird 2000SSS Attesa in October 1989, possibly as Nissan's rally project. From 1990 through to 1994 it was used in the infamous Nissan Pulsar GTi-R (N14) however with a bigger T28 turbo. In both these cars the engine is aligned in a East/West fashion.
However the Nissan Silvia and Nissan 180SX produced in 1991 were built with the SR20DET aligned in a North/South fashion because of the rear wheel drive gearbox. Almost all of the 180SX's were released with the SR20DET.
The engine then went on to be used in the Nissan Avenir in 1995, the Nissan Rnessa in 1997 and the Nissan Liberty in 1999, although these models did not gain the cult status that the earlier produced models did.
Out of all the Nissan models produced with the SR20DET, the Silvia was the longest running model to use it. The latest model, the S15, uses a bigger turbo. The Garrett T28.
