The Nissan SR engine is a 1.6 L, 1.8 L, or 2.0 L straight-4 4-stroke internal combustion gasoline engine manufactured by Nissan Motors. It features an aluminum head and aluminum block with steel sleeves and features a DOHC 4-valve design, with variable valve timing on select models. The engine was used in many small to medium Nissan vehicles including high-performance turbocharged variants. It was designed by Nissan as a replacement for the earlier CA series of engines. Power output shown is JIS Net PS or ECE Net kilowatts unless otherwise indicated.sr20ve
The SR20DET was first produced in the U12 Nissan Bluebird 2000SSS Attesa in October 1989 [1]. From 1990 through to 1994 it was used in the Nissan Pulsar GTi-R (RNN14) however with a bigger T28 turbo. In both these cars the engine is aligned in a transverse fashion.
However the RWD Nissan Silvia produced from 1991 were built with a longitudinally aligned SR20DET.
The engine was used in the Nissan Avenir in 1995, the Nissan R'nessa in 1997 and the Nissan Liberty in 1999.
Out of all the Nissan models produced with the SR20DET, the Silvia was the longest running model to use it. The S14 and S15 use a bigger turbocharger than the S13 models.
