Looking for a reliable and cost-effective replacement for your tired or failed Subaru EJ255 engine? J-Spec Auto Sports offers the JDM EJ20X 2.0L Turbocharged Quad Cam Engine – a long block solution that serves as a strong, compatible swap for the 2007–2012 Subaru WRX.

The EJ20X is a 2.0-liter DOHC turbocharged boxer engine imported from the Japanese market. It features Quad Cam configuration and Dual Active Valve Control System (AVCS) on both the intake and exhaust cams, delivering smoother power delivery and improved engine response across the rev range compared to its USDM counterpart.

While the EJ20X is a JDM-only motor, it is widely used in the U.S. as a long block replacement for the EJ255 due to its similar mounting points, timing configuration, and head design. It pairs well with the USDM intake and exhaust manifolds, sensors, and ECU when swapped over from your original EJ255 setup.

Key Features:

• JDM EJ20X 2.0L DOHC Turbo Boxer Engine

• Dual AVCS (Intake + Exhaust)

• Quad Camshaft Design

• Cast Iron Closed Deck Block with Aluminum Heads

• Turbocharger Compatibility

• Excellent Compression Across All Cylinders

• 90-Day Start-Up Warranty from J-Spec Auto

This engine is best suited for enthusiasts looking to maintain or enhance factory performance while keeping OEM reliability. It’s a budget-friendly option that provides better availability than USDM EJ255 engines and is a go-to for WRX owners, tuners, and rebuilders.

At J-Spec Auto Sports, all JDM engines are thoroughly inspected and compression tested before shipping. Backed by our 90-day start-up warranty, the EJ20X offers peace of mind and dependable Subaru performance.
