Article Discussion

Template:One source Template:Infobox automobile engine

The SR engine is a series of Template:Convert, Template:Convert or Template:Convert straight-four, four-stroke gasoline engines manufactured by Nissan. It has an aluminium head and block with steel sleeves and has a DOHC 4-valve design, with variable valve timing on select models. It was added to a new engine family name PLASMA (Powerful ＆ Economic, Lightweight, Accurate, Silent, Mighty, Advanced).

The engine was used in many small to medium Nissan vehicles, including high-performance turbocharged variants. It was designed by Nissan as a replacement of the earlier CA series of engines, and was replaced by the QR and MR series of engines. Power outputs are shown under JIS Net PS or ECE Net kilowatts unless otherwise indicated.

SR16VEEdit

The Template:Convert SR16VE has Nissan's Neo VVL variable valve timing with lift control. It produces Template:Convert at 7800 rpm and Template:Convert at 7200 rpm. Redline is at 8300 rpm. Bore and stroke is Template:Convert with a 11.0:1 compression ratio.

This engine was never used on the USDM counterpart of the B14 Lucino, the B14 Nissan 200SX, as it uses the 1.6 L GA16DE and 2.0 L SR20DE engines instead.

It is used in the following vehicles:

SR16VE N1Edit

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 Template:Convert at 7800 rpm and Template:Convert 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.Template:Citation needed

SR18DiEdit

The SR18Di is a Template:Convert DOHC engine. It produces Template:Convert at 6500 rpm and Template:Convert 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 of the P10/11 Primera, the Infiniti G20, as it uses the 2.0 L SR20DE engine instead.

It is used in the following vehicles:

SR18DEEdit

The SR18DE is a Template:Convert DOHC engine. It produces Template:Convert at 6000 rpm and Template:Convert 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.

This engine was never used on the USDM counterpart of the P10/11 Primera, the Infiniti G20, as it uses the 2.0 L SR20DE engine instead.

It is used in the following vehicles:

SR20DiEdit

The SR20Di is a Template:Convert DOHC engine. It produces Template:Convert. Bore and stroke are Template:Convert. Similar to the 1.8 liter version except for bigger displacement with a throttle body injection system.

This engine was never used on the USDM counterpart of the P10/11 Primera, the Infiniti G20, as it uses the 2.0 L SR20DE engine instead.

It is used in the following vehicles:

SR20DEEdit

The SR20DE is a Template:Convert DOHC engine. It was used in over 15 Nissan models, first appearing in the U12 Bluebird in October 1989. It was gradually phased out over time with the introduction of the low-emissions QR engine family in 2000, until production stopped in 2002. It carried nominal power ratings between Template:Convert 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
