Nissan SR engine

The SR engine is a series of 1.6 L (1,596 cc), 1.8 L (1,838 cc) or 2.0 L (1,998 cc) 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.

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.

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:

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]

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 of the P10/11 Primera, the Infiniti G20, as it uses the 2.0 L SR20DE engine instead.
