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.

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.

The SR20DE is a 1998 cc 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 1999, until production stopped in 2002. It carried nominal power ratings between 125-165 hp 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.
