Subaru R1 Engines - Codes, Common Failures & Replacement Costs

The cards below cover the EN07-series engines fitted to the Subaru R1 in the UK, including documented failure causes, variant production years, and typical replacement costs based on current UK market data for grey import specialists.

Subaru R1 engine intelligence reference

EN07D

Production History

  • Subaru R1 S (JA chassis) - 2005-2007
  • Subaru R1 S (JB chassis) - 2008-2010
  • Subaru R1 Aero, Limited (JA/JB chassis) - 2005-2010

Known Failures

  • Oil consumption - piston ring wear increases oil use after 60k miles on high-mileage grey imports.
  • Timing chain tensioner wear - cold start rattle on units exceeding 70k miles without proper maintenance.
  • VVT solenoid wear - causes rough idle and warning lights on higher-mileage Japanese imports.

Specs

Petrol · 0.66L · 54hp · Naturally Aspirated

Replacement Cost

Typical UK rebuilt engine: £1,400-£2,200 (supply only) Estimated from comparable EN07 units - actual quotes may vary.

EN07X

Production History

  • Subaru R1 STi (JA chassis) - 2006-2007
  • Subaru R1 STi, STi Aero (JB chassis) - 2008-2010

Known Failures

  • Supercharger bearing wear - whining noise and boost loss after 50k miles on enthusiast-driven grey imports.
  • Intercooler hose degradation - boost leaks common on high-mileage units causing reduced performance.
  • Timing chain tensioner wear - cold start rattle exacerbated by supercharger heat cycles.

Specs

Petrol · 0.66L · 64hp · Supercharged

Replacement Cost

Typical UK rebuilt engine: £1,800-£2,600 (supply only) Estimated from comparable EN07X units - actual quotes may vary.

EN07U

Production History

  • Subaru R1 Limited, S Low Emission (JB chassis) - 2007-2010

Known Failures

  • Oil consumption - revised piston rings reduce but do not eliminate oil use on high-mileage units.
  • Emissions system sensitivity - UK MOT compliance requires proper catalytic converter function.
  • VVT solenoid wear - causes rough idle and emissions test failures on urban-driven imports.

FAQ

  • Japanese used EN07 engines start from £500 with auction grade verification

Compare Subaru R1 engine replacement quotes from vetted UK specialists

What engine code fits my Subaru R1-

All Subaru R1 variants use the EN07-series 0.66L petrol engine code, but chassis codes JA (2005-2007) and JB (2008-2010) determine compatibility with your vehicle's mounting points and emissions systems.

  • EN07 is the dominant engine family code across S, Aero, Limited and STi variants
  • Verify chassis code JA for pre-facelift or JB for facelift compatibility before ordering
  • Enter your registration above for instant DVLA-verified engine code confirmation
  • EN07X supercharged and EN07U low-emission codes require specialist verification for correct replacement matching
Verify your Subaru R1 EN07 engine code instantly via DVLA lookup

Is a reconditioned Subaru R1 engine better than a used Japanese import-

Reconditioned EN07 engines offer UK warranty coverage and upgraded components addressing known failures like supercharger bearing wear, while used Japanese imports provide lower upfront cost but limited warranty and potential compliance documentation gaps.

  • Reconditioned units include 12-month UK warranty vs 3-6 months for Japanese imports
  • Rebuilt EN07 engines feature upgraded piston rings addressing R1 failure patterns
  • Japanese imports require additional IVA/MOT documentation verification for UK compliance
  • Budget-conscious owners may prefer imports; long-term owners benefit from reconditioned reliability
Compare reconditioned vs used Subaru R1 engine options with warranty details

Will a replacement engine affect my Subaru R1 UK MOT or registration-

Replacement engines must meet UK emissions standards and include proper documentation for DVLA registration; EngineMarket specialists supply EN07 units with Euro 4 certification and IVA support for grey import compliance.

  • All replacement EN07 engines include UK-spec catalytic converter for MOT emissions compliance
  • Emissions certification documentation provided for DVLA registration updates on grey imports
  • IVA test support included for R1 vehicles requiring Individual Vehicle Approval
  • Specialists handle ECU immobiliser adaptation and i-CVT calibration for seamless UK registration transfer
Find MOT-compliant Subaru R1 engine replacements with full documentation

How long does Subaru R1 engine replacement take in the UK-

UK reconditioned EN07 engines typically dispatch within 2 days; Japanese imports require 10-14 days delivery plus 1 day fitting. Supply & fit bookings can often be scheduled within 48 hours for in-stock units.

  • In-stock UK reconditioned units: 2-day supply & fit turnaround typical for EN07 variants
  • Japanese import engines: 10-14 days delivery plus 1 day specialist fitting with chassis verification
  • i-CVT and supercharged variants may require additional time for adaptation service and drivetrain compatibility checks
  • Emergency replacement helpline available for seized engine scenarios with priority dispatch from UK stock
Check live Subaru R1 engine stock availability and delivery timelines

Can I fit a Subaru R1 engine myself to save money-

DIY engine fitting is not recommended for Subaru R1 grey imports due to kei car-specific tools, i-CVT adaptation requirements, supercharger calibration and UK compliance documentation best handled by specialists.

  • EN07-series engines require specific lifting equipment and timing tools for safe installation
  • i-CVT variants need ECU adaptation service - specialist tooling essential for smooth operation
  • IVA/MOT documentation support requires specialist knowledge of grey import compliance procedures
  • Supply & fit packages often cost less than DIY when factoring tool hire, risk of errors and warranty validity
Book Subaru R1 engine supply & fit with grey import specialist network

What are the most common Subaru R1 engine problems-

EN07X supercharger bearing wear causing whining noise and boost loss, timing chain tensioner rattle on cold start, and oil consumption on high-mileage naturally aspirated EN07D units dominate Subaru R1 replacement enquiries from UK grey import owners.

  • Supercharger bearing failure affects EN07X/EN07Z variants; rebuilt units include upgraded bearings as standard
  • Timing chain tensioner wear common on all EN07 variants; revised tensioners available on rebuilt engines
  • Oil consumption from piston ring wear on NA units; upgraded rings included on rebuilt EN07D/EN07Y
  • All rebuilt EN07 units include upgraded components addressing these known grey import failure points
Compare Subaru R1 engine replacements with failure-proof upgraded components

Is it worth repairing or replacing my Subaru R1 engine-

If repair costs exceed 60% of a reconditioned EN07 price (£1,400-£2,200), replacement offers better long-term value with UK warranty coverage and upgraded components addressing original failure patterns.

  • Minor repairs (supercharger rebuild, tensioner replacement) cost £280-£950 and may be viable for low-mileage units
  • Major failures (seized supercharger, timing chain jump) typically require full replacement for reliability
  • Rebuilt EN07 engines include 12-month warranty vs limited coverage on repaired original units
  • Consider vehicle value: R1 grey imports typically worth £1,500-£3,500 in UK market
Get instant repair vs replace cost comparison for your Subaru R1 variant

Does the Subaru R1 engine work with Daihatsu/Toyota donor parts-

Yes - the EN07 engine was also fitted to Daihatsu Mira, Move and Toyota bB in other markets, expanding UK parts availability and reducing lead times for grey import R1 owners seeking replacement components.

  • EN07 cross-compatibility increases donor pool for hard-to-find R1-specific components
  • Piston rings, tensioners and sensors often available from Daihatsu/Toyota kei car suppliers in UK
  • Verify part numbers match your R1 chassis code (JA/JB) and variant before ordering
  • EngineMarket specialists source from cross-platform kei car inventory to reduce wait times
