About this engine family

The QR family of inline-four piston engines by Nissan were introduced in 1999 and range from 2.0 to 2.5 L in displacement. These motors are aluminum, dual overhead camshaft (DOHC), four-valve designs with variable valve timing and optional direct injection. The engine shares much of its architecture with the YD diesel engine.

In detail

The QR20DE produces at 6000 rpm and at 4000 rpm. The bore and stroke is and a compression ratio of 9.9:1. The QR20DE was replaced with the MR20DE engine in most applications in early 2005. Vehicle applications: 2001-2007 Nissan X-Trail T30, 2001-2007 Nissan Primera P12 2002–present Nissan Serena C24, 2003-2008 Nissan Teana J31, 2001-2005 Nissan Wingroad Y11 2002-2005 Nissan Avenir W11 2001-2004 Nissan Prairie M12 2007-2020 Nissan Atlas F24 2014-present Nissan Urvan E26 The QR20DD is similar to the QR20DE but features NEO direct injection to improve fuel economy and to reduce emissions.

It produces at 6000 rpm and at 4400 rpm. Vehicle applications: 2000-2004 Nissan Bluebird Sylphy The QR25DE is a variant built with cast steel connecting rods, a steel timing chain, counter-rotating balance shafts, and an aluminum intake manifold. The engine bore and stroke is and a compression ratio ranging from 9.5:1 to 10.5:1 depending on the vehicle. Output is rated at 6000 rpm with of torque at 4000 rpm in the Altima 2.5 and Sentra SE-R models.

The Sentra SE-R Spec V originally claimed 180 hp, but this was adjusted downward to 175 once production started in late 2001. The redline is 6100 rpm. Altimas that are PZEV compliant create and of torque.In the 2005+ Nissan Frontier the QR25DE generates and of torque.[http://www.nissannews.com/nissan/2006vehicles/frontier/specs.shtml The revised QR25DE found in the 2007+ Sentra, Altima, Rogue, etc. has a number of improvements over the older QR25DE.

These include: A simpler, larger diameter single path resin intake manifold replaced the old dual path design. (Note: California emissions models do have a swirl control valve located in the intake) Revised piston crown shape to support a higher compression ratio of 9.6:1.(10.5:1 in Sentra SE-R Spec V.) The balancer system has been moved back slightly from the crank pulley to a more centric location in the block. Revised cam shaft profile.

Reinforced connecting rods only available in the Sentra SE-R Spec V 2007-2012 . Reduced friction likely through Nissan's extensive use of coatings on pistons, journal bearings, etc. Additional engine mount on the top of the motor, pulley side. Higher rev limit and improved power output. 1999–2003 Nissan Bassara 2001–2005 Nissan Serena C24 2001–2007 Nissan X-Trail T30 APEC export version 2002–2006 Nissan Sentra SE-R & SE-R Spec V 2002–2009 Nissan Presage 2002–2020 Nissan Altima to 2003–2005 Nissan Teana 2003–2014 Nissan Murano (Japan) 2005–2019 Nissan Frontier 2007–2012 Nissan Sentra SE-R & SE-R Spec V 2007–2011 Nissan Altima Hybrid , combined 2007–2020 Nissan X-Trail T31 2007–2023 Renault Koleos TR25 2008–2020 Nissan Rogue 2009–2012 Suzuki Equator 2010–present Nissan Elgrand E52 2013–2020 Nissan Teana 2013–present Nissan X-Trail T32 2014-present Nissan Urvan E26 2018–present Nissan Terra- 2020–present Nissan X-Terra- The QR25DD is similar to the QR25DE but increases the compression ratio to 10.5:1 and includes direct injection.

This engine is also the first QR to use DLC coating on the valve lifter buckets for reduced friction. It produces at 5600 rpm and at 4000 rpm. Vehicle applications: 2002-2006 Nissan Primera P12 (JDM) The QR25DER is similar to the QR25DE but has a supercharger for increased power and is coupled with a electric motor, Dual Clutch System, and lithium-ion battery for increased fuel efficiency. The engine has a compression ratio of 9.1:1 (10.0:1 in 2014 Infiniti QX70) and produces a combined at 5600 rpm and at 3600 rpm.

Vehicle applications: 2014 - 2015 Nissan Pathfinder Hybrid 2016 only Nissan Murano Hybrid 2014 - 2017 Infiniti QX60 Hybrid
