JDM Subaru WRX EJ205 Single AVCS Engine

Has your 2006–2014 WRX blown its EJ255? If so, this used JDM EJ205 single AVCS engine offers an affordable way to get back on the road. It’s the 2.0L turbocharged boxer from the Japanese-market Subaru Impreza WRX. Moreover, it shares the same engine family and single-AVCS design as the US 2.5L EJ255. As a result, many shops use it as a cost-effective replacement.

Why Choose a JDM EJ205?

A new or rebuilt EJ255 can cost several thousand dollars, and rebuilds often take weeks. In contrast, a JDM EJ205 costs far less and is ready to install. Also, Japan’s strict shaken inspection rules push many owners to retire their cars early. For that reason, JDM engines often come from well-maintained, relatively low-mileage vehicles. On top of that, the EJ205 has a strong reputation, and Subaru tuners know it well.

EJ205 vs EJ255: What to Know Before You Swap

The EJ205 and EJ255 share the same basic design, but they are not identical. First, the EJ205 displaces 2.0 liters instead of 2.5, so it makes a little less low-end torque. However, it loves to rev, and many drivers enjoy its eager character. Second, because of the displacement difference, your car will need a professional ECU tune to run correctly. Finally, installers commonly transfer certain parts from the original EJ255, such as the intake manifold, sensors or accessories, depending on the car. So, we recommend that an experienced Subaru shop handle the swap.

Compression Tested Before It Ships

We don’t guess about engine health. Instead, we compression test every cylinder and record a video of the test. Also, the photos on this page show this exact engine, including its serial number. That way, you know exactly what you’re getting before it arrives.

Before You Install

Every used engine benefits from some fresh service before startup. Therefore, we recommend checking or replacing the timing belt, tensioner and idlers. In addition, replace the spark plugs, oil, filter and coolant, and inspect the seals and hoses. Finally, prime the oil system and confirm the turbo oil feed before the first start. These simple steps help protect your investment for years to come.

FAQ

Will this fit my 2010 WRX?
Yes, as a replacement for the EJ255, with a professional ECU tune and some parts transferred from your original engine. Call us with your VIN to plan the swap.

What’s the difference between single AVCS and dual AVCS?
Single AVCS adjusts only the intake cams, like the US 2006–2014 WRX EJ255. Dual AVCS engines adjust both intake and exhaust cams and need different wiring and control.

Do I need a tune?
