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-four, four-stroke gasoline internal combustion engine manufactured by Nissan Motors. It has an aluminum head and block with steel sleeves and has 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.

SR16VE

The 1.6 L (1,596 cc) SR16VE has Nissan's Neo VVL variable valve timing with lift control. It produces 175 PS (129 kW; 173 hp) at 7800 rpm and 119 lb⋅ft (161 N⋅m) at 7200 rpm. Redline is at 8300 rpm. Bore and stroke is 86 mm × 68.7 mm (3.39 in × 2.70 in) with a 11.0:1 compression ratio.

It is used in the following vehicles:

• N15 Nissan Pulsar VZ-R
• B14 Nissan Lucino VZ-R
• B15 Nissan Sunny VZ-R

SR16VE N1

This version was used in the limited-production Pulsar VZ-R N1, produced from 1997 to 1998. These cars were tuned by Autech Japan. It made 200 PS (197 hp; 147 kW) at 7800 rpm and 134 lb⋅ft (182 N⋅m) at 7600 rpm. Redline of the N1 Version 2 (1998) is at 8600 rpm. This is also claimed to be the most powerful production 1.6 L naturally aspirated engine.^{[citation needed]}

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 four fewer counterweights than the SR20DE variants, which have eight, for lighter weight and better fuel efficiency. These lightweight 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 116 PS (114 hp; 85 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:

• 1991–1994.6 Nissan Primera
• 1992- 1995 Nissan Silvia

SR20DE

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 125–165 hp (127–167 PS; 93–123 kW) from the factory. Although there are some Autech models with horsepower ratings of between 175 and 200 hp depending on the chassis and degrees of tuning.

The breakdown of the engine code is as follows:

• SR - Engine
• 20 - 2.0 Litres
• D - Dual Overhead Cams
• E - Electronic Fuel Injection

SR20DET

P11 2.0

Origins

The SR20DET was first produced in the U12 Nissan Bluebird 2000SSS Attesa in October 1989 . 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 was 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.
