The Nissan SR engine is a 1.6 L (1,596 cc), 1.8 L (1,838 cc) or 2.0 L (1,998 cc) straight-4, four-stroke gasoline internal combustion engine manufactured by Nissan Motors. It features an aluminum head and 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 (1,838 cc) DOHC engine. It produces 110 PS (108 hp; 81 kW) at 6500 rpm and 150 N⋅m (111 lb⋅ft) at 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:

• 1990-1993 Nissan Primera
  


• Nissan Sunny


• Nissan Bluebird U12


• 
  Nissan Avenir W10

SR18DE

The SR18DE is a 1.8 L (1,838 cc) DOHC engine. It produces 125 PS (123 hp; 92 kW) at 6000 rpm and 156 N⋅m (115 lb⋅ft) at 4800 rpm. This engine came with Multi Point Fuel Injection System ECCS (Electronic Concentrated Control System). The SR18DE crankshaft was produced with 4 less counterweights than the SR20DE variants, which have 8, for better fuel efficiency. These light weight crankshafts were also homologated for use in the Japanese N2 Silvia racing program and later used in the SR20VE engine.

It was used in the following vehicles;

• 1991-1997 Nissan Primera
  


• Nissan Sunny


• 
  Nissan Avenir W10


• Nissan Rasheen


• 1991-1997 Nissan Bluebird U13
  


• 1989-1998 Nissan Bluebird U14 119 PS (117 hp; 88 kW) Factory detuning and refining of fuel injection.


• 1990-1993 Nissan Pulsar GTi B13 and N14, 140 PS (138 hp; 103 kW) at 6400 rpm and 167 N⋅m (123 lb⋅ft) at 4800 rpm


• 1991-1999 Nissan Pulsar GTi N15, 140 PS (138 hp; 103 kW) at 6400 rpm and 167 N⋅m (123 lb⋅ft) at 4800 rpm


• 1989(??)-2001 Nissan Presea 125 PS (123 hp; 92 kW)

SR20Di

The SR20Di is a 2.0 L (1,998 cc) DOHC engine. It produces 122 PS (120 hp; 90 kW). Bore and stroke are 86 mm × 86 mm (3.39 in × 3.39 in). Similar to the 1.8 liter version except for bigger displacement with a throttle body injection system.

It is used in the following vehicles:

• 1991-1994.5 Nissan Primera
  


• 1992- 1995 Nissan Silvia

SR20DE

SR20DE engine from a 2001 Infiniti G20.

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 128–160 hp (130–162 PS; 95–119 kW) from the factory.

The breakdown of the engine code is as follows:

• 
  SR - Engine


• 
  20 - 2.0 Litres


• 
  D - Dual Overhead Cams


• 
  E - Electronic Fuel Injection

This engine has the following specifications (SAE, 1991)

It was used in the following vehicles:

SR20DET

P11 2.0

Origins

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 produced from 1988 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

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

• S13 Black top – 180sx's post-94 (Garrett T25G turbo)


• S13 Red top – S13 Silvia and 180sx pre-94 (Garrett T25G turbo)


• S14 Black top – 1994-98 (notchtop) Silvias – Variable Cam Timing aka VCT was introduced on the intake cam (Garrett T28 journal bearing turbo for Australian and European markets and Garrett T28 Ball Bearing turbo for the Japanese market)^[1]


• S15 Black top – 1999-2002 Silvias. As S14 but with PTU within ignition coil packs, 6-speed manual transmission (Garrett Journal Bearing T28 for Europe and Australia and Ball Bearing T28 turbo for Japan)
