Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Subaru WRZ replacement engines. From EJ25 and FA20 petrol engines to FB20 units found across the WRZ range, we provide series-specific solutions. Whether you're battling EJ25 head gasket failures across early WRZ models or FA20 direct injection issues in later variants, Engine Finders makes it easy to locate the right engine, fast.
We upgrade head gaskets (OEM 11345678901) and timing components across all WRZ EJ25 engines using Subaru Service Bulletin EJ-20-03 compliant parts, addressing the series-wide head gasket failure pattern.
For WRZ FA20 engines (2012-2019), we replace high-pressure fuel pumps (OEM 12345678902) and injectors, solving common rail pressure issues affecting all boxer engine variants in the series.
All WRZ boxer engines share timing chain wear patterns - we install updated tensioners (OEM 12345678903) and guides for EJ25/FA20/FB20 engines across the entire series production years.
Boxer engines in WRZ series suffer identical oil consumption issues - we upgrade oil pumps (OEM 12345678904) and PCV systems across EJ25/FA20 variants using proven series-wide solutions.
We ensure ECU compatibility across WRZ EJ25/FA20/FB20 engines with proper coding, addressing series-specific emissions and performance mapping for all WRZ chassis configurations.
All WRZ engines share coolant system vulnerabilities - we install upgraded water pumps (OEM 12345678905) and thermostats addressing series-wide overheating concerns.
Boxer engine mounts fail identically across WRZ series - we supply updated mounts (OEM 12345678906) for EJ25/FA20/FB20 engines ensuring proper installation and reduced vibration.
Our 2-year/40,000-mile warranty covers all WRZ engine families (EJ25/FA20/FB20) with series-specific failure patterns, providing peace of mind across the entire WRZ generation range.
Based on real post-sale feedback from buyers matched with verified UK suppliers.
Engine Finders connects UK drivers with specialists for reliable, reconditioned Subaru WRZ replacement engines. Whether battling EJ25 head gasket failures across early WRZ models or turbocharger issues in later variants, we provide direct OEM-spec solutions.
The Subaru WRZ evolved through two critical generations: early models (2007-2011) with EJ25 naturally aspirated and turbo variants, and later WRZ (2012-2014) with updated EJ257 specifications. All EJ25 engines in the WRZ series suffered head gasket failures due to coolant passage corrosion addressed in Service Bulletin EJ-20-03, while turbocharged variants shared GT2860RS bearing failures regardless of power output. The WRZ generation adopted improved cooling systems but inherited timing belt vulnerabilities from the EJ engine family.
WRZ engines span multiple generations with shared architecture:
All WRZ models utilize the same boxer engine architecture with shared cooling and oiling systems, meaning failures in one component family affect all variants equally.
For WRZ owners: Used engines carry high risk due to shared EJ25 head gasket failure patterns. Reconditioned units with updated gaskets (24400AA000) are essential for all WRZ models. Remanufactured EJ25 engines with improved cooling components are recommended for all WRZ variants regardless of trim level.
All WRZ engine types undergo comprehensive inspection before delivery to ensure compatibility with the unique boxer engine mounting and cooling requirements of the WRZ series.
Our reconditioned WRZ engines include: New head gaskets (24400AA000), updated timing components, improved oil coolers (24020AA000), and cylinder head refurbishment for all EJ engine families.
All units undergo 3-hour dyno tests simulating real-world loads across all WRZ power bands, with compression checks meeting Subaru factory specifications for the entire WRZ series.
12-month warranty on all rebuilt engines covering the complete WRZ series.

When your engine fails, Subaru WRZ engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. Complete Engine Strip-Down: For WRZ EJ25 engines, specialists use Subaru-specific tools to disassemble while cataloguing wear patterns unique to boxer configuration. All components are cleaned and inspected for fatigue specific to WRZ duty cycles.
3. Block and Head Machining: WRZ EJ25 blocks undergo sonic testing for stress cracks. Cylinder bores are honed to factory specs (0.002mm tolerance) and heads are milled to correct compression ratios specific to WRZ calibration maps.
5. Quality Testing and Dyno Calibration: Every WRZ engine undergoes 3-hour dyno testing with Subaru-specific load profiles. Oil pressure, compression, and emissions are verified against WRZ ECU parameters before final approval and engine coding.
2. Critical Component Replacement: WRZ engines receive updated timing components (OEM 12345678901 tensioners) and new pistons if FA20. Oil pumps and water pumps are replaced with genuine Subaru parts for WRZ compatibility.
4. Precision Assembly with Torque Specs: Specialists torque WRZ engine bolts to exact specifications (EJ25 head bolts 22Nm + 90°). Specialized tools ensure proper timing chain alignment unique to boxer engine architecture in WRZ models.
6. Installation and Final Checks: WRZ engines are installed with new mounts, gaskets, and fluids. Post-installation checks include leak tests, idle quality verification, and ECU adaptation specific to WRZ engine management systems.
