Its. The Truth Behind The Subaru EJ Series Engines Tech Knowledge. Once known simply as the automotive company that built modest commuter cars like the Brat 7. Subaru a division of Fuji Heavy Industries became internationally known for their boxer engines. Beginning in 1. 98. Subarus horizontally opposed EJ series motors are the mainstay engines of their model lineup, with all EJ series engines sharing a 1. So why has Subaru continued their love affair with the boxer engine Utilizing a boxer engine configuration similar to what was once used in older model Volkswagens, Subaru has continued use of the boxer engine with good reason. The Subaru boxer engine is a unique engine thats anything but typical. Engineer Karl Benz patented the flat four engine in 1. In 1. 97. 1, inspired by airplane engine design, Fuji Heavy Industries, through the Subaru brand, released their interpretation of the flat four.

This design provided a lighter weight and compact, economic design for Subaru. In all, there have been 2. EJ motors, including the 1. WRX STi model that develops 3. Subaru engines have always been known to be well engineered that are both powerful and torquey, but Subaru engineers left a lot to be desired when it came to the EJ2. USDM WRX, EJ2. 55 USDM WRX 0. EJ2. 57 0. 4 to0. USDM WRX STi turbocharged models. This month, we get in depth with three of the top Subaru tuners in the world, as they help dispel myths and speak their minds about the infamous EJ series engine. Yimi Sport Tuning of Santa Clarita, CA, has been serving the Subaru community since 2. How To Convert Idx File To Csv on this page. Yimi Sports not only caters to customer cars but are avid participants at various road race events such as Super Lap Battle and Import Tuner EVO vs. STi Shootout, including this year when they took home the title of fastest Subaru. Q Focusing on the EJ2. EJ2. 55, and EJ2. Is there a secret recipe that can better educate Subie owners on how to build their engines to increase horsepower output and longevity A The EJ series motors are good motors, and we would not call them weak per se. P/sparco_harness_bar.jpg' alt='How To Install Racing Seats In 350Z Forum' title='How To Install Racing Seats In 350Z Forum' />On a stock motor, the two primary weaknesses are the stock cast hypereutectic pistons and oiling to the rod bearings. The pistons particularly on the EJ2. EJ2. 57 will crack if subjected to knockdetonation events. Obviously, with proper ECU tuning the engine can be kept away from the knock threshold, making the pistons not as much of an issue. Oiling to the rod bearings is the other primary issue. We typically dont see very many problems with the EJ2. EJ2. 57 in this respect, but do see it more on the older EJ2. Fundamentally there isnt a big difference between the 2. L and 2. 5. L motors in terms of the design of the oiling system but the EJ2. From the factory, the allowable range of bearing clearance is pretty broad and if you dont use quality synthetic oil and change it often it can lead to problems. The same can be said of any motor, so while not a strong point of the EJs, it should not be painted as a bad motor because of it. We dont believe in secret formulas, but rather common sense. En Bons Termes 9Th Edition. In the case of making EJ motors last, it boils down to proper ECU tuning by a reputable tuner who clearly understands the logic of the ECU and its interaction with the engine, along with regular maintenance and using quality fluids in the car.

Is it true that the 0. Subarus require tuning with every aftermarket component installed or risk a potential loss in horsepower A Its not the engine that is more difficult to tune, it is the ECU that has gotten more complex on the newer cars. As long as the tuner understands the functions and logic of the ECU, the newer cars are no more or less difficult to tune than the older cars.

This month, we go indepth with three of the top Subaru tuners in the world, as they help dispel myths and speak their minds about the infamous Subaru EJseries engine. Ideally youd always want a custom tune to be performed with the exact combo of parts that are going to be run for the foreseeable future. Unfortunately, Subaru chose an unfortunate ECU tuning strategy in more recent years mostly 0. Federal emissions compliance. Basically there is a long delay in the switchover from closed to open loop operation that forces the car to run very lean fueling even as loadboost rises. At that point, knockingpingingdetonation is almost unavoidable and the resulting concussive pressure wave will crack the piston ring lands. In large part, this is what has caused some people to believe that the EJ motors are weak, but the underlying cause is actually in the ECU tuning. Ben 10 Theme Pack For Windows 7. Auto Master AMR, located in Mamaroneck, NY, is a family owned and operated establishment with over 5. AMR is known to build some of the worlds highest horsepower cars, from nitrous oxide to forced induction, and currently holds the record for the worlds quickest and fastest 0. STi 7. 7. 5 1. STi with a quarter mile record of 1. Q What are some of the drawbacks of the WRX and STi engines internal design, and the limitations on how much horsepower they can handle A The Subaru EJ series engines are put together very well from the factory. Though not equipped with forged internals, the factory engine in its stock form can handle double its factory power output. A majority of engine failures are caused by uneducated tuners who dont understand how the vehicle and its engine work, along with not knowing the consequences of using low quality parts to handle their horsepower expectations. The Subaru EJ series motor is unlike any OEM engine on the market. We at AMR have pushed these motors, with our internal forged components and performance parts, to over 1,0. The bottom line is an educated tuner, high quality performance parts, and an educated driver will equal a reliable vehicle. Q Whats a common misconception when building an engine A The most common is believing the block needs to be sleeved. Most people jump right to them at 4. Q What are the most overlooked issues that cause mistakes when building engines to handle an increase in horsepowerA Plain and simple, it would have to be checking proper clearances and tolerances.
