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.
SR18Di
The SR18Di is a 1.8 L (1838 cc) DOHC engine. It produces 110 PS (81 kW) @6500 rpm and 150 nm @4000 rpm. Based on the Single Point Fuel Injection system, it was installed on JDM cars and some UK versions. This model used some cast iron blocks and it was used on the P10 generation Nissan Primera, but due to the low overall power this engine option was dropped on the next generation.
This engine was never used on the USDM counterpart the Infiniti G20

- 1990-1993 Nissan Primera
- Nissan Sunny
- Nissan Bluebird U12

SR20DET
P11 2.0
Origins
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.
