TheSR engine is a series of 1.6 to 2.0 L (1,596 to 1,998 cc)straight-four,four-stroke gasolineengines manufactured byNissan from 1987 to 2007. It was part of a new engine family name PLASMA (Powerful ＆ Economic, Lightweight, Accurate, Silent, Mighty, Advanced).
TheSR engine family uses aDOHC 4-valve design, withvariable valve timing on select models, and is an all-aluminium design with an aluminium head and block with steelsleeves. All SR engines arechain-driven rather thanbelt-driven, unlike previous Nissan four-cylinder engines.
The SR engine was designed by Nissan as a replacement of the earlierCA series of engines, which used cast iron blocks and timing belts, and was later replaced by theQG,QR andMR series of engines. It was used in many small to medium Nissan vehicles, including various high-performanceturbocharged variants.
Power outputs are shown underJIS NetPS orECE Netkilowatts unless otherwise indicated.
The 1.6 L (1,596 cc)SR16VE hasNissan'sNeo VVLvariable 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.
This engine was never used on theUSDM counterpart of the B14 Lucino, theB14 Nissan 200SX, as it uses the 1.6 LGA16DE and 2.0 L SR20DE engines instead.
It is used in the following vehicles:
This version was used in the limited-productionPulsar VZ-R N1, produced from 1997 to 1998. These cars were tuned byAutech 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 Lnaturally aspirated engine.[citation needed]
TheSR18Di 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 theSingle 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 generationNissan Primera, but due to the low overall power this engine option was dropped on the next generation.
This engine was never used on theUSDM counterpart of the P10/11 Primera, theInfiniti G20, as it uses the 2.0 L SR20DE engine instead.
It is used in the following vehicles:
TheSR18DE 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 betterfuel efficiency. These lightweight crankshafts were also homologated for use in the Japanese N2 Silvia racing program and later used in theSR20VE engine.
This engine was never used on theUSDM counterpart of the P10/11 Primera, theInfiniti G20, as it uses the 2.0 L SR20DE engine instead.
It is used in the following vehicles:
TheSR20Di 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.
This engine was never used on theUSDM counterpart of the P10/11 Primera, theInfiniti G20, as it uses the 2.0 L SR20DE engine instead.
It is used in the following vehicles:
TheSR20DE is a 2.0 L (1,998 cc) DOHC engine. It was used in over 15 Nissan models, first appearing in the U12Bluebird in October 1989. It was gradually phased out over time with the introduction of the low-emissionsQR engine family in 1999, until production stopped in 2002. It 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.
