FAQ Review the Boxer EJ25 Engine from Subaru

The Subaru Impreza’s top models have an EJ20 turbocharge and EJ25 turbocharge. When shopping for a Subaru, you don’t need a turbocharged engine.


How much does it cost to replace a Subaru EJ25 boxer engine?

Although you can want to own one of these rally-bred saloons, it can be difficult to maintain the EJ25 turbo motor. We will begin our Engine Series by explaining the basics of owning a Subaru with an EJ 25 turbo-charged engine, how it drives, and any other issues that you may run into during your ownership. Although the following information may be a bit broad and general, I can credit them as I have owned and driven the 2008 GH8 Impreza WRX for six years and have had my fair share of issues and fun with it. Let’s first look at Subaru’s history with Subaru’s most beloved boxer motor. Source URL

What are the problems with the Subaru EJ25 boxer engine?

The EJ25 is difficult to reach, and the plugs can be difficult to locate. However, the EJ 25 also has larger problems that have yet to be resolved. Subaru fans use the term “ringland failure” or “spun conrod bearings” to refer to an engine that is dead. A ringland failure happens when the piston ring’s seat deforms on the piston. This causes the piston to lose compression. A spun connecting rod bearing is a spinning connecting rod that pushes the piston in the wrong direction during combustion cycles. This means that your pistons won’t compress anything if it isn’t in sync. Although there are many reasons why this happens, there are still many arguments as to why it happens. Source URL

How can I improve the reliability of my Subaru EJ25 boxer engine?

Subaru’s EJ25 has these critical issues so it is important to consult and research before you attempt to fix it. You should consult experts who have had extensive experience with these motors and have had good reliability. They will tell you to first consider reliability before you add power. Your motor’s life can be preserved by a good tune, upgraded cooling components such as radiators and oil coolers, and power steering coolers. Sources say that the problem with an EJ25’s lubrication is the reason for all of its problems. It is worth looking at improving the engine’s problems. Source URL

How much horsepower does a 2019 Subaru WRX S209 have?

The powertrain follows Subaru’s classic formula: a four-cylinder Boxer engine with turbocharged four cylinder engine driving all four wheels. It is mated with a six-speed manual transmission. The S209’s familiar EJ25 2.5-liter four cylinder engine is under the hood. This engine produces 341 horsepower at 6,400 rpm and 330 pounds-feet torque at 3,600 revs. This is 31 horsepower and 40 lb-ft more than the WRX STI’s 2.3-liter engine. An HKS-built turbocharger, which is larger than the one in the WRU STI, and has a higher maximum boost of 18.9 pounds per square inch (PSI), is the reason for the turbochargers. Source URL

What is the difference between Subaru FB25 and EJ25?

The FB25 engine is more responsive at lower engine speeds than EJ25. It has the same power, but a lower rpm and increased torque at lower rpm. The fuel efficiency of the FB25 is better than the EJ26. These features make the Subaru 2.5-liter Subaru engine a better and more suitable choice. Source URL

What is the difference between Subaru Forester EJ25 and FB25?

Subaru has made the FB-series engine. The 2.5-liter FB25 boxer four-cylinder engine replaced the EJ25 engine in Legacy and Forester models. This engine was first produced in 2010. Source URL

What is the difference between EJ and EJ2 engine?

The engine has the new cylinder aluminum block with a lower piston bore. The same displacement can be achieved by increasing piston stroke. This gave the engine a little more torque at low revs. To keep the engine’s exterior dimensions the same as the EJ-series engine, there are asymmetrical connecting rods. Source URL
