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. SR18DiThe SR18Di is a {{convert|1838|cc|L|1|abbr=on|order=flip}} DOHC engine. It produces {{Convert|110|PS|hp kW|0|abbr=on}} at 6500 rpm and {{Convert|150|Nm|lbft|0|abbr=on}} 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:
SR18DEThe SR18DE is a {{convert|1838|cc|L|1|abbr=on|order=flip}} DOHC engine. It produces {{Convert|125|PS|hp kW|0|abbr=on}} at 6000 rpm and {{Convert|156|Nm|lbft|0|abbr=on}} 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;
SR20DiThe SR20Di is a {{convert|1998|cc|L|1|abbr=on|order=flip}} DOHC engine. It produces {{Convert|122|PS|hp kW|0|abbr=on}}. Bore and stroke are {{convert|86x86|mm|2|abbr=on}}. Similar to the 1.8 liter version except for bigger displacement with a throttle body injection system. It is used in the following vehicles:
SR20DEThe 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 {{Convert|128-160|hp|PS kW|0|abbr=on}} from the factory. The breakdown of the engine code is as follows:
This engine has the following specifications (SAE, 1991)
It was used in the following vehicles:
SR20DETP11 2.0 {{main|Nissan SR20DET}}OriginsThe SR20DET was first produced in the U12 Nissan Bluebird 2000SSS Attesa in October 1989 [https://web.archive.org/web/20070328081220/http://english.auto.vl.ru/catalog/nissan/bluebird/1989_10/24020/]. 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 colorsThe colors of the valve covers seem to be related to the year the engine was released.
It was available in the following vehicles:
SR16VEThe {{convert|1596|cc|L|1|abbr=on|order=flip}} SR16VE has Nissan's Neo VVL variable valve timing with lift control. It produces {{Convert|175|hp|PS kW|0|abbr=on}} at 7800 rpm and {{Convert|119|lbft|Nm|0|abbr=on}} at 7200 rpm. Redline is at 8300 rpm. Bore and stroke is {{convert|86x68.7|mm|abbr=on}} with a 11.0:1 Compression Ratio. It is used in the following vehicles:
SR16VE N1This 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 {{Convert|200|PS|hp kW|0|abbr=on}} at 7800 rpm and {{Convert|134|lbft|Nm|0|abbr=on}} 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|date=November 2018}} SR20VE{{Self-contradictory|about=|date=November 2018}}The {{convert|1998|cc|L|1|abbr=on|order=flip}} SR20VE has Nissan's Neo VVL variable valve timing with lift control. It produces {{Convert|190|PS|hp kW|0|abbr=on}} at 7000 rpm and {{Convert|144|lbft|Nm|0|abbr=on}} at 6000 rpm and later (2001–2003) {{Convert|205|PS|hp kW|0|abbr=on}} at 7200 rpm and {{Convert|206|Nm|lbft|0|abbr=on}} at 5200 rpm with a 10.3:1 Compression Ratio. It is used in the following vehicles:
SR20VETAvailable as original equipment only in the Japanese market, the {{convert|1998|cc|L|1|abbr=on|order=flip}} SR20VET was the first turbocharged engine from Nissan with variable valve lift (VVL). It produces {{Convert|280|PS|kW hp|0|abbr=on}} at 6400 RPM and {{Convert|309|Nm|lbft|0|abbr=on}} at 3200 RPM, with 9.0:1 Compression Ratio. It is used in the following vehicles:
