Nissan Roox Engine ReplacementCompare Prices & Save

The Nissan Roox uses 660cc three-cylinder petrol engines only - either the K6A (2009-2016) or R06A (2016-present) family, with naturally aspirated or turbocharged variants.

• All Roox engines are 0.66L petrol, complying with kei-car regulations
• K6A engines shared with Suzuki Alto/Wagon R for parts compatibility
• R06A engines feature updated timing chain design for improved reliability
• Turbo variants (K6A-T, R06A-DET) deliver maximum 64hp kei-car output

Yes, the K6A engine in early Roox models (2009-2016) is identical to the Suzuki Alto HA24 and Wagon R, dramatically expanding UK sourcing options.

• K6A engine codes are fully interchangeable between Roox and Suzuki
• R06A engines (2016+) are Nissan-specific with limited Suzuki overlap
• Always verify engine code before ordering a replacement unit
• Suzuki-compatible K6A engines often more readily available in UK

No, the HR12DE 1.2L engine from Nissan Note/Micra is NOT compatible with the Roox - different mounting, ECU, and displacement.

• HR12DE is 1.2L four-cylinder; Roox uses 0.66L three-cylinder only
• Mounting points, wiring harness and ECU are completely different
• Ordering an HR12DE for a Roox will result in costly fitting errors
• Always confirm your Roox engine code is K6A or R06A before purchasing

Heat cycles and vibration in the compact kei engine bay degrade original ignition coils, causing misfires typically between 60k-90k miles.

• K6A engines most commonly affected due to age and design
• Symptoms include rough idle, loss of power and check engine light
• Replacing all three coils together prevents near-future repeat failures
• Rebuilt engines include upgraded coil packs as standard

Typical UK rebuilt engine prices range from £850-£2,100 for K6A units and £1,100-£2,600 for R06A, supply-only, depending on turbo specification.

• Naturally aspirated K6A engines are the most affordable option
• Turbo variants (K6A-T, R06A-DET) command higher prices
• Supply & fit services add £450-£850 to engine cost
• All EngineMarket suppliers include minimum 12-month warranty

K6A and R06A engines are generally reliable for kei-car applications, but specific high-mileage failures like ignition coils and timing chains are well-documented.

• Regular oil changes critical for turbo variant longevity
• Ignition coil replacement recommended preventatively at 60k miles
• Timing chain tensioner inspection advised after 80k miles
• Rebuilt engines address known failure points with upgraded components

Ignition coil failure on K6A engines (2009-2016) is the most frequently reported issue, followed by timing chain stretch on higher-mileage R06A units.

• K6A coil failures cause misfires, rough running and EML illumination
• R06A timing chain issues manifest as rattling on cold start
• Turbo variants add turbocharger seal wear to the failure profile
• All common failures are addressed in EngineMarket rebuilt engines

Yes, JDM import engines are available, but verify mileage, compression test results and warranty terms before purchasing.

• Request compression test report and service history documentation
• Confirm engine code matches your vehicle exactly (K6A vs R06A)
• Factor in shipping costs and import documentation processing time
• UK-sourced rebuilt engines often offer better warranty coverage

With proper maintenance, K6A and R06A engines typically reach 80k-120k miles before major component replacement is considered.

• Regular oil changes every 5k miles critical for turbo longevity
• Ignition coils and timing components are wear items requiring attention
• CVT transmission health affects perceived engine performance
• Rebuilt engines with upgraded components can extend service life significantly
