Subaru EJ engine - Wikipedia. The Subaru EJ engine is a series of four- stroke automotive engines manufactured by Subaru. They were introduced in 1. Subaru EA engine. The EJ series is the mainstay of Subaru's engine line, with all engines of this series being 1. SOHC or DOHC). Naturally aspirated and turbocharged versions are available, ranging from 9. These engines are commonly used in light aircraft, kit cars and engine swaps into air- cooled Volkswagens, and are also popular as a swap into the wasserboxer engined Volkswagen T3/Vanagon . Primary engineering on the EJ series was done by Masayuki Kodama, Takemasa Yamada and Shuji Sawafuji of Fuji Heavy Industries, Subaru's parent company. The practice began with the designation of the USA- spec turbo, commonly referred to as the EJ2. T, and the habit of referring to any turbocharged engine as a . When referring to the EJ2. T, one is speaking of one of the following: EJ2. G engines fall into 3 categories: 1. Rocker- style HLA EJ2. G usage. Engines can be identified by coil on plug, and with 2 M6 bolts per coil and valve covers with 4. CAM 1. 6VALVE and horizontal lines above and below the plug holes. All these engines have the air- to- water intercooler setup (chargecooler) and close deck blocks equipped with piston oil squirters. Bucket- style HLA EJ2. G usage. Pistons in this type of EJ2. G are all cast aluminum. Closed- deck engine block equipped with piston oil squirters was used until mid 1. Followed by Open- deck block equipped with piston oil squirters was used very short period of time, Followed by Open- deck block from 1. EJ2. 0K WRX engines came out. The open deck block on all EJ2. G could be identified by a smoother surface, and a tab on the right surface of the block halves. The EJ2. 0G continued to be used in the WRX Wagon with an Automatic Transmission from 1. EJ2. 05. 3. Shim- under- bucket style EJ2. G usage. Engines can be identified by coil on plug with 1 M8 bolt per coil and valve covers with 4.

The driver space was maintained reasonably well, with maximum. The Subaru World Rally Team (SWRT) was Subaru's World Rally Championship (WRC) team. It used a distinctive blue with yellow color scheme that is a throwback to the. Subaru Prices and Values: Subaru, a Japanese manufacturer, is known for being one of the top vehicles in the rally racing community. The use of its exclusive. CAM 1. 6VALVE and horizontal lines above the plug holes. Generally these engines all have the slanted intercooler. Some engines may not have HLA buckets but solid buckets with shims underneath. These engines also feature lighter valves, the intake valves are marked INKO and the exhaust valves are marked EXKO. The standard HLA valves are I2. E2. 83 respectively. All WRX Wagon engines and automatic sedan engines came with a TD0. WRX sedans including STI versions had a TD0. EJ2. 0K engines fall into 2 categories: 1. Shim- over- bucket style EJ2. K usage. Shim- under- bucket style EJ2. About Justin Stobb Justin Stobb is the Owner of All Wheel Drive Auto, the premier Independent Subaru Shop in the North West. Justin has been providing Subaru Owners. The Subaru Legacy was redesigned for the 2015 model year. Side ratings are assigned by the Institute based on a test conducted by Subaru as part of side crash test. If a lightweight and track-focused McLaren is what you want, then look away from this Lego 1:1 scale 720S because it is neither light nor would it hold up well in a. One of the more common repairs we make to Subaru’s are CV (Constant Velocity) boots. Pictured below is a CV or Drive axle on a Subaru. Subaru actually calls the. K usage. These engines can be identified by smooth valve covers, plug leads and a wasted spark coil in the middle of the intake manifold. In addition, the inlet manifold may be bare aluminum for all WRX models and red for all STI models. The engine utilizes an IHI ball- bearing turbo unit. VF2. 2 on the WRX, either a VF2. VF2. 4 on the STI. These engines have die- cast pistons for all WRX models, STI and STI type. RA/STI type R models shares exactly the same factory forged pistons. This engine series is used for WRX models in the world market outside Japan as of 1. The Japanese WRX models use the EJ2. EJ2. 05. After 2. WRXs use the EJ2. USDM WRX model changed engines to the EJ2. The EJ2. 05 has an 8: 1- 9: 1 compression ratio. To identify an EJ2. Coil on plug, except in JDM SF5 forester. Usage: Impreza WRX9. JDM Wagon Body only)0.

EJ2. 05 does not have coil on plug but can be identified from the VIN of the vehicle (if known) where the 1. Y (for year 2. 00. Digit will be 8 (for the 2. EJ2. 05)It started its life for the 9/9. GC8 in Japan, UK, Australia. The EJ2. 07 has an 8. The TGV are deleted from the factory. The factory deletion is incomplete, even on the Spec C and even on the Type RA. The exhaust is compatible all the way to the downpipe to the USDM WRX/Sti. Oxygen sensor is same as USDM EJ2. The oil pan is like the USDM WRX 2. The Turbo is the VF3. The ECU has the same number and shape harness plugs as the USDM WRX 2. No immobilizer. The engine speed is limited from the factory at 8. V8, 9 are twinscroll, AVCS, throttle by cable, topfeed injectors, engines. There are no TGV's, the intake manifold is one piece. The spark plugs are specified one step colder, compared with other Sti. The exhaust is completely different/incompatible with the USDM WRX/Sti, all the way from the header to the downpipe. It can be replaced by a USDM exhaust, the USDM does bolt up to the block. The oil pan is like the USDM Sti. The turbo is a VF3. The ECU has the same number and shape harness plugs as the USDM WRX 2. There is no immobilizer for V8 and for some V9. The V9 known so far to not have immobilizer have been early V9 Spec C (revision E engines). The engine speed is limited from the factory at 8. When compared with the USDM A/C compressor, the JDM Sti is of a different part number and smaller in size. It is possible that the losses while using it are smaller. Many have an additional intake air temperature sensor by the throttle body. Its function has been discussed but not completely clarified. The power steering pump is different. The JDM cars included some Spec C with 1. The pump remained the same, so it is designed to handle a fast rack. The com protocol is not canbus for any of these. Some of the Sti engines don't come with provision for cruise control. It is next to impossible to tell which had it. The ROM settings are quite different from a V7. The turbo inlet has one less connection in it and most likely is of a larger diameter than the USDM, from the factory. The front Oxygen sensor has been relocated after the turbo, in the downpipe. Different part number 2. AA0. 42. Usage: EJ2. X/EJ2. 0Y. The EJ2. X engine was introduced in the 2. Legacy GT, mated to a five- speed automatic transmission, and the EJ2. Y engine was introduced in the 2. Legacy GT, with a five- speed manual transmission. The EJ2. 0X and EJ2. Y are open deck engines whereby the cylinder walls were supported at the three and nine o’clock positions. It came with an aluminium alloy block with 9. The EJ2. 0X engine is understood to have a forged crankshaft and connecting rods, but cast aluminium pistons with forged crowns. The EJ2. 0X and EJ2. Y engines had an aluminium alloy cylinder head with cross- flow cooling, double overhead camshafts (DOHC) per cylinder bank and four valves per cylinder that were actuated by roller rocker arms. The EJ2. 0X and EJ2. Y engines were the first EJ engines to be equipped with Subaru’s . For the BL. I Legacy GT, the EJ2. X engine was fitted with a twin- scroll IHI VF3. EJ2. 0Y engine, however, had a larger twin- scroll Mitsubishi TD0. HLA 1. 9T turbocharger. For the revised BL. II Legacy GT, both the EJ2. X and EJ2. 0Y had an IHI VF4. IHI VF4. 5. Both came with a 9. However, similar to the EJ2. T, the term was never used by Subaru. Used from 1. 99. 4 to 2. Due to the tight confines of the engine bay, the twin turbo engine was installed in Japanese- spec Legacies only, which were right- hand drive. The Pistons were lighter with a shorter skirt than the WRX EJ2. T to allow for higher engine speed. Specifications. All secondary turbos are ball bearing and primary turbos are journal bearing. Usage: Impreza 9. Legacy 9. 0- 9. 9, Outback 9. Specifications. Accomplishing this involves many factors, one of which is engine friction reduction. The pistons were coated with molybdenum to reduce friction. The thin coating reduces moving friction and reduces cylinder wall scuffing. The piston skirt was reshaped and the piston weight was reduced by approximately 1. Compression ratio was increased to 9. This eliminates the clearance that was available between the piston at TDC and the fully opened valve. Piston pin offset has been changed to 0. Piston to cylinder wall clearance has been reduced by increasing the piston diameter. Another source of high engine friction is the valve train. Hydraulic lash adjusters (HLAs) are always in contact with the valves. The hydraulic pressure of the lash adjuster must be overcome during operation and during the most critical time of engine start. To overcome this situation and to contribute to the total reduction of friction loss, 1. SOHC engines have solid valve adjusters. The scheduled service of this valve train is set at 1. SOHC engines now use an adjustment screw to adjust valve clearance. Engines with the earlier HLA are recommended to use 1. W3. 0 or 1. 0W4. 0 oil year- round; 5. W3. 0 can be used at very low winter temperatures. The roller rocker cam follower system that was introduced on the 1. L Impreza engines, is installed on all 1. The roller assemblies are not serviceable separately, but the rocker arms may be serviced as individual units. The carbon composition head gaskets with integrated o- rings are interchangeable from left to right on 1. NA engines only. Other Engine Modifications (2. L 1. 99. 7): The intake manifold has been reshaped to increase the airflow mass and speed, contributing to improved low and mid engine speed operation. Components located on the intake manifold have been relocated as compared to the 1. EGR Solenoid, Purge Control Solenoid, etc. Liter Phase 2 Engine Enhancements (from endwrench article H- 4 and H- 6 service): All 2. Phase 2 design. The 2. Phase 2 engines are a SOHC design, with a newly designed cylinder head. Changes in the 2. Phase 2 engines are as follows: the engine and transmission are fastened with six bolts and two studs. Additional Phase 2 Engine Features: the cylinder head is a two- rocker shaft, solid type valve system with roller followers. The intake valves are positioned 2. Prior model year engines utilized a 1. An IN1 or IN2 will be embossed on each rocker arm. As viewed from the front of the engine the Number 1 intake valve of each cylinder and the number 2 intake valve have an IN1 marked and IN2 marked rocker arm that mates with it. New IN1 rocker arms can also be identified by a Green painted mark on the top of the rocker arm.
