List of Subaru engines - wikipedia List of Subaru engines Subaru uses a four or five character code to identify all of their engines. The first letter is always E standing for engine ( before the introduction of FB engine series ) The second letter is the engine 's family. Next come two digits indicating the engine 's displacement ( or revision before 1989 ) The optional fifth character is an identifier to mark revisions, ( ex : turbo, DOHC, Fuel Injection, etc. ) Contents 1 Two Cylinder 1.1 EK 1.1. 1 Two - strokes 1.1. 2 Four - strokes 2 Three Cylinder 2.1 Subaru EF engine 3 Four Cylinder 3.1 Subaru EA engine 3.2 Subaru EE engine ( diesel ) 3.3 Subaru EJ engine 3.4 Subaru EL engine 3.5 Subaru EN engine 3.6 Subaru FA engine 3.6. 1 FA20D 3.6. 2 FA20F 3.7 Subaru FB engine 3.7. 1 FB16 3.7. 2 FB16 DIT 3.7. 3 FB20B 3.7. 4 FB20D 3.7. 5 FB20X 3.7. 6 FB25B 4 Six Cylinder 4.1 Subaru ER engine 4.2 Subaru EG engine 4.3 Subaru EZ engine 4.3. 1 EZ30D 4.3. 2 EZ30D 4.3. 3 EZ36D 5 See also 6 Notes 7 External links Two cylinder EK The EK series is a straight twin two - stroke cycle with early air - cooled versions later replaced with water - cooled configurations in 1971. The engine was upgraded to a four - stroke SOHC in 1973 to meet Japanese Government emission regulations. The ( Japanese : Subaru EK series ) was used from 1958 until 1989 in most Kei car models.

It is not compliant with Japanese Government regulations concerning displacement of kei cars with a current maximum limit of 660 cc. The EF appeared while the EK was being replaced by the EN05. Subaru EF - 12 Engine Subaru EF engine EF10 : Bore x Stroke mm = 78.0 x 69.6 Piston displacement = 997 cc Compression ratio = 9.5 : 1 Two valves per cylinder SOHC 2V, 55 hp at 5,200 rpm 1984 -- 1987 Subaru Justy EF12 : Bore x Stroke mm = 78.0 x 83.0 Piston displacement = 1189 cc Compression ratio = 9.1 : 1 Three valves per cylinder SOHC 3V, 66 - 73 hp 1987 -- 1994 Subaru Justy Four cylinder All of Subaru 's four - cylinder engines ( except the EN series ) are liquid - cooled, horizontally opposed boxer four - strokes. Subaru EA engine The EA was used from 1966 until 1994 in most models. It is a basic two - valve - per - cylinder design with siamese ports and three main crankshaft bearings. Engines with overhead camshafts were installed with two timing belts, whereas vehicles with overhead valves used timing gears exclusively. Subaru EA82 Engine EA52 : 977 cc OHV, 55 hp at 6,000 rpm used in the 1966 -- 1971 Subaru 1000 EA61 : 1088.8 cc OHV, 62 hp at 6,400 rpm used in the 1970 -- 1972 Subaru FF - 1 Star and Subaru G EA62 : 1267.5 cc OHV, 80 hp at 6,400 rpm used in the 1971 -- 1972 Subaru G EA63 : 1362 cc OHV, 58 hp at 5,200 rpm used in the 1973 -- 1976 Subaru Leone EA71 : 1595 cc OHV, 67 hp at 5,200 rpm or 68@4800 rpm used in the 1976 -- 1987 Subaru Leone and 1978 -- 1980 Subaru BRAT / brumby EA81 : 1781 cc OHV, 73 hp at 4,800 rpm used in the 1980 -- 1984 Subaru Leone and 1981 -- 1993 Subaru BRAT / brumby EA81T : 1781 cc OHV Turbo, 95 hp at 4,200 rpm used in the 1983 -- 1984 Subaru Leone and Subaru BRAT / brumby EA82 : 1791 cc SOHC, 84 - 97 hp used in the Subaru Leone and Subaru XT EA82T : 1791 cc SOHC, 115 hp at 5200 rpm used in the Subaru Leone and Subaru XT Subaru EE engine ( diesel ) Subaru unveiled the world 's first boxer diesel engine to be fitted in a passenger car at the Geneva autoshow in 2007. This 2.0 L DOHC engine, called the EE20, has 147 HP and 350Nm ( 258 lb - ft ) of torque, five main bearings and was released in Europe in 2008. Engine was originally Euro - 4 certified, updated to Euro - 5 in 2008 and Euro - 6 in 2015. 1998 ccm, Bore 86mm, Stroke 86mm Subaru EJ engine The EJ engine was introduced in the 1989 Subaru Legacy to replace the EA engines. It was designed from scratch with five main crankshaft bearings and four valves per cylinder and can be either SOHC or DOHC and one timing belt. The fifth digit is the only way to tell without seeing the engine. Subaru EJ20H twin turbo EJ15 : 1483.4 cc SOHC, 1990 -- 2003 JDM Subaru Impreza EJ16 : 90 hp at 5,600 rpm used in the 1993 -- 2006 Subaru Impreza EJ18 : 1820 cc SOHC 110 hp at 5,600 rpm used in the 1993 -- 1996 Subaru Impreza and Euro and JDM Subaru Legacy EJ20 : 1994.3 cc, available in Europe and Japan naturally aspirated at 115 -- 190 hp and with a Turbo 220 -- 280 hp used on Most Models, ( 2002 -- 2005 WRX in the United States ) EJ22 : 2212 cc, 135 -- 280 hp used in the 1989 -- 2001 Subaru Impreza and Subaru Legacy EJ25 : 2457 cc, 165 -- 320 hp found in Most Models 1995 -- Present EJ30 : Special limited engine. Four were built by Subaru, but only 3 remain in working condition. There is no readily available technical or power information on these engines. Generally the EJ - series can be divided into two versions : the Phase I engines ( 1989 -- 1998 ) and the Phase II engines ( 1999 -- 2010 ). The Phase II engines featured new cylinder heads and crankshafts with the thrust bearing located at crank bearing # 5 instead of # 3. The designation also changed from Phase I to Phase II. All Phase I engines have an alphanumerical suffix behind the standard EJXX designation, all Phase II engines have a numerical suffix behind the EJXX designation. Example : Phase I : EJ15E, EJ15J, EJ16E, EJ18E, EJ20D, EJ20E, EJ20G, EJ20H, EJ20J, EJ20R, EJ20K, EJ22E, EJ221, EJ25D Phase II : EJ151, EJ161, EJ181, EJ201, EJ202, EJ203, EJ204, EJ205, EJ206, EJ207, EJ208, EJ222, EJ251, EJ252, EJ253, EJ254, EJ255, EJ257 There 's at least 1 exception from this rule - MY'07 EJ20F engine. Most likely F stands for bi-Fuel ( engines prepared for LPG ). This is unconfirmed info, based only on users ' experience and observations. Subaru EL engine The ( Japanese : Subaru EL engine ) replaced the EJ15 and is used in the JDM Subaru Impreza 1.5 R ( series GD, GG, GE, GH ) starting with model year 2006. It is based on the EJ engine and shares many components, like the crankshaft from the EJ25. It has DOHC cylinder heads with AVCS variable valve timing on the intake. Displacement : 1,498 cc bore x stroke : 77.7 x 79 mm compression ratio : 10.1 maximum horsepower : 110ps ( 81 kW ) @ 6400 RPM maximum torque : 14.7 kgm ( 144Nm ) at 3,200 rpm AVCS Subaru EN engine The Subaru EN inline - four engine was introduced in 1988 to replace the straight - two EK series engine that was originally engineered as an air - cooled engine and then was modified as a water - cooled engine used in the 1969 -- 1972 Subaru R - 2. The EN is used in all kei cars and kei trucks currently in production by Subaru. Subaru FA engine ( Japanese : Subaru FA engine ) The FA was developed from the FB engine, however, efforts to reduce weight while maintaining durability were the main goals of the FA engine. While the FA and FB engines share a common platform, the FA shares very little in dedicated parts with the FB engine, with a different block, head, connecting rods, and pistons. FA20D Subaru FA20D The FA20D features both direct and port injection ( Toyota 's D - 4S injection system ) and Subaru AVCS variable valve timing system. It is used in the Subaru BRZ, and is identified by a Toyota engine family code known as the 4U - GSE, which is installed in the Toyota 86 and the Scion FR - S. According to Subaru, 0W - 20 oil is recommended. Bore : 86 mm Stroke : 86 mm Displacement : 1,998 cc Compression Ratio : 12.5 : 1 Power : 200 PS ( 147 kW ; 197 hp ) at 7,000 RPM Torque : 20.9 kg m ( 205 N m ; 151 lb ft ) at 6,400 - 6,600 RPM Fa20f Subaru FA20F A version with Subaru 's own direct fuel injection and twin - scroll turbocharger was introduced in 2012.

By increasing piston stroke and decreasing piston bore, Subaru aimed to reduce emissions and improve fuel economy, while increasing and broadening torque output over the previous generation engine. The FB has an all new block and head featuring dual overhead cams with intake and exhaust variable valve timing ( AVCS - Active Valve Control System ), and a timing chain that replaced the timing belt. Moving to chain - driven cams is said to allow the valves to be placed at a more narrow angle to each other and shrink the bore of cylinder from 99.5 mm to 94. It results in less unburned fuel during cold start, thereby reducing emissions. Subaru is able to maintain the exterior dimension substantially unchanged by asymmetrical connecting rods like those in EZ36. The FB is only marginally heavier. In Jan 2011, Car and Driver was told direct injection would be added soon. Subaru claims a 28 - percent reduction in friction losses, mainly due to lighter pistons and connecting rods. The FB has a 10 % improvement in fuel economy with the power coming on sooner and the torque band being broader.

Subaru er engine ( Japanese : Subaru ER27 ) Subaru introduced its first six - cylinder engine in its Subaru XT sports car. This SOHC engine was based on the EA82, with two cylinders added to the back. ER27 : 2672 cc SOHC, 145 hp@5200 found in the 1987 -- 1991 Subaru XT Subaru EG engine The ( Japanese : Subaru EG33 ) engine was a direct replacement for the ER engine. The ER had been used only in the Subaru XT6, which was being replaced by the Subaru Alcyone SVX, and the company took the opportunity to create a new engine based on the more modern EJ rather than the EA engine series. As the ER27 was to the EA82, Subaru took the EJ22 design and created a six - cylinder version to make the new EG33. However, this four - valves - per - cylinder engine was DOHC, and valvetrain parts came from the not yet released EJ25D. Bore : 96.9 mm Stroke : 75 mm EG33 : 3318 cc DOHC, 230 hp@5400 used in the 1992 -- 1997 Subaru Alcyone SVX Subaru EZ engine Subaru EZ36 The ( Japanese : Subaru EZ series ) was introduced in 1999 in the Japanese market, in the Subaru Outback, and in 2000 in the United States market, also in the Outback. It is a flat - six, 24 - valve, quad - cam engine with an aluminium block and heads. It is available in EZ30 and EZ36 variants. Though the second iteration of the EZ30D used from 2003 to 2009 was heavily updated from the early EZ30D used from 2001 to 2003, Subaru continued to identify it as EZ30D. `` EZ30R '' is a false engine code often used on the Internet for the later EZ30, but Subaru has never used it as an official engine code. All EZ - series engines use dual timing chains and feature coil - on - plug ignition. EZ30D This version uses one exhaust port per head, a cable - actuated throttle, variable intake geometry, and a cast aluminium intake manifold. It was only available with an automatic transmission. Displacement : 2999 cc DOHC Bore : 89.2 mm Stroke : 80 mm Compression : 10.7 : 1 Power : 220 PS ( 162 kW ; 217 hp ) at 6000 rpm Torque : 289 N m ( 29 kg m ; 213 lb ft ) at 4400 rpm Application : 2000 -- 2004 Subaru Outback H6 2000 -- 2002 Subaru Legacy GT30 2000 -- 2002 Subaru Legacy Lancaster 6 EZ30D This version received new cylinder heads with 3 exhaust ports per head, AVLS, AVCS on the intake cams only, a drive - by - wire throttle, and a plastic intake manifold. It was available in manual and automatic unlike the old EZ30D. Displacement : 2999 cc DOHC Bore : 89.2 mm Stroke : 80 mm Compression : 10.7 : 1 Power : 245 PS ( 180 kW ; 242 hp ) at 6600 rpm Torque : 297 N m ( 30 kg m ; 219 lb ft ) at 4200 rpm Application : 2003 -- 2009 Subaru Legacy 3.0 R 2005 -- 2009 Subaru Outback 3.0 R 2006 -- 2007 Tribeca EZ36D The EZ36D retains the plastic intake manifold, 3 exhaust ports per head, and drive - by - wire throttle of the later EZ30D, but loses AVLS while gaining AVCS for both intake and exhaust cams. The EZ36D also incorporates an asymmetrical connecting rod design shared with the FB series of engines and the EE20 diesel engine. Displacement : 3629 cc DOHC Bore : 92 mm Stroke : 91 mm Compression : 10.5 : 1 Power : 260 PS ( 191 kW ; 256 hp ) at 6000 rpm Torque : 335 N m ( 34 kg m ; 247 lb ft ) at 4400 rpm Application : 2010 - current Subaru Legacy 2010 - current Subaru Outback 2008 - 2014 Subaru Tribeca See also Subaru 1235 List of Subaru transmissions Notes Jump up ^ Michael Knowling ( April 2, 2004 ). `` 2004 Engine Epic - Subaru Engines ''.
