Subaru R1 Engines for Sale | Engine Finders

Engine Finders connects UK drivers with specialists for reliable, reconditioned Subaru R1 replacement engines. Whether battling EJ15 timing chain issues or head gasket failures across the R1 series, we provide direct OEM-spec solutions.

Subaru R1 Replacement Engines

The Subaru R1 evolved from 2005-2010 with the EJ15 engine family powering all variants. All R1 models share the same 1.5L EJ15 naturally aspirated engine with common timing chain and head gasket failure patterns. The EJ15 in R1 vehicles uses identical components regardless of trim level, with timing chain guides and tensioners wearing consistently across the production run. Subaru issued technical service bulletins addressing EJ15 head gasket issues affecting all R1 variants during their production period.

Subaru R1 Models & Engines Codes

The R1 series exclusively used the EJ15 engine family throughout its production run from 2005-2010, with all variants sharing identical powertrains and common failure points.

  • EJ15: 1.5L naturally aspirated (2005-2010) - Timing chain guides and head gaskets fail across all R1 variants
  • EJ15B: Base 1.5L variant (2005-2010) - Same components as standard EJ15 with identical failure patterns
  • Chassis compatibility: All R1 models (GF-A platform) share identical engine mounts and installation requirements

All R1 variants share the same EJ15 engine architecture, meaning replacement strategies and common failures are consistent across the entire model range regardless of trim level.

Buy Used and Second-Hand Subaru R1 Engines

For R1 owners: Used EJ15 engines carry high risk due to known timing chain and head gasket issues affecting all variants. Reconditioned units with updated timing components are essential for long-term reliability across the R1 series.

  • Used EJ15 engines: Risk of inherited timing chain wear and head gasket issues
  • Reconditioned units: Updated timing chain guides and tensioners for all R1 variants
  • Remanufactured engines: Complete EJ15 rebuild with improved components across all specifications
