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 in selected models 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[edit]

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

It is used in the following vehicles:

SR18DE[edit]

The SR18DE is a 1.8 L (1838 cc) DOHC engine. It produces 125 PS (92 kW) @6000 rpm and 156 nm @4800 rpm. This engine came with Multi Point Fuel Injection System ECCS (Electronic Concentrated Control System).

It was used in the following vehicles;

SR20Di[edit]

The SR20Di is a 2.0 L (1998 cc) DOHC engine. It produces 122 PS (89 kW). Bore and stroke are 86 mm (3.4 in) and 86 mm (3.4 in). Similar to the 1.8 liter version except for bigger displacement with a throttle body injection system.

The Nissan SR20DE engine was used in over 15 Nissan models. It first appeared in October 1989, and over time it was gradually phased out with the introduction of the QR (low-emissions) engine family. The SR20DE carried nominal power ratings between 130 to 169 Horsepower (96 to 126 kW) from the factory.

The breakdown of the engine code is as follows:

  • SR - Engine Code
  • 20 - 2.0 Litres
  • D - Dual Overhead Cam
  • E - Multi-port Fuel Injection

SR20DET[edit]

Origins[edit]

U13 Bluebird SR20DET. (FWD/AWD layout)

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 and produced in 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.

Valve cover colors[edit]

The colors of the valve covers seem to be related to the year the engine was released.
