Nissan Dayz Engine ReplacementCompare Prices & Save

Nissan Dayz engine replacement costs typically range from £1,200 to £4,500 depending on engine code, turbo status, and whether you choose used, reconditioned or rebuilt. Grey import logistics and specialist fitting expertise also affect final pricing.

• BR06DE naturally aspirated engines: £1,200-£2,100 rebuilt supply only
• BR06DET turbo engines: £1,400-£2,800 rebuilt supply only
• e-POWER hybrid HR12DE: £2,200-£4,500 due to specialist requirements
• Supply & fit service adds £400-£900 labour depending on location

Your Nissan Dayz uses either the BR06DE (naturally aspirated), BR06DET (turbo), or HR12DE (e-POWER hybrid) engine code, depending on variant and chassis generation. Enter your registration or chassis code to confirm exact compatibility.

• B21W chassis (2013-2019): BR06DE or BR06DET only
• B33W chassis (2019+): BR06DET or HR12DE e-POWER
• Turbo variants (X, Highway Star, Bolero, Rider) use BR06DET
• e-POWER hybrids exclusively use HR12DE generator system

Typical Nissan Dayz engine replacement takes 2-3 weeks total: 7-14 days for Japan sourcing and UK delivery, plus 4-8 hours for specialist fitting once the engine arrives.

• Used engines from Japan: 7-10 day delivery typical
• Rebuilt units held in UK: 1-3 day dispatch possible
• Fitting time: 4-6 hours NA, 6-8 hours turbo or hybrid
• Allow buffer time for ECU calibration and road testing

Yes, all Nissan Dayz engines supplied through EngineMarket include a minimum 12-month unlimited mileage warranty from vetted UK JDM specialists, covering parts and labour for rebuild-related failures.

• Warranty valid UK-wide with specialist fitting confirmation
• Covers internal components, turbo, timing system on rebuilt units
• e-POWER hybrid warranties include inverter and generator coverage
• Always confirm exact terms with your chosen supplier before ordering

Some UK garages will fit customer-sourced Nissan Dayz engines, but warranty validity and liability for compatibility issues may be limited. EngineMarket recommends bundled supply & fit for grey import peace of mind.

• Specialist fitting requires JDM kei-car experience and ECU tools
• Warranty often void if engine not sourced through supplier network
• Risk of incorrect variant or calibration if chassis code not verified
• Bundled supply & fit simplifies logistics and protects your investment

Used Nissan Dayz engines are as-is from Japan; reconditioned units have key wear parts replaced; rebuilt engines receive comprehensive overhaul with upgraded components addressing known failure points and full testing.

• Used: Lowest cost, variable history, limited warranty
• Reconditioned: Balanced value, basic wear items replaced
• Rebuilt: Highest reliability, upgraded parts, 12-month warranty standard
• Rebuilt BR06DET includes UK-spec turbo calibration as standard

Replacing your Nissan Dayz engine with a like-for-like JDM-spec unit typically does not change your insurance group, but you must declare the modification to your insurer to maintain policy validity.

• Like-for-like BR06DE/BR06DET swaps rarely affect premiums
• e-POWER hybrid replacements require specialist declaration
• Keep documentation: invoice, warranty certificate, engine number update
• Failure to declare may invalidate claims after replacement

If your Nissan Dayz shows severe symptoms like knocking, seized rotation, or compression loss below 100 PSI across cylinders, replacement is likely more cost-effective than repair for grey import owners facing parts delays.

• Get a compression test and leak-down diagnosis first
• Repair may suit minor issues: sensor faults, external leaks, actuator failures
• Replacement preferred for internal damage, high-mileage wear, or turbo failure with secondary damage
• Use our repair vs replace calculator with import logistics factors

Upgrading a Nissan Dayz from BR06DE to BR06DET turbo or adding e-POWER hybrid components requires ECU reprogramming, potential chassis modifications, and may affect insurance-consult a JDM specialist before proceeding.

• Turbo swap requires boost calibration, intercooler, exhaust and ECU changes
• Hybrid conversions are complex and rarely cost-effective for grey imports
• Performance upgrades may void warranty and require insurer notification
• Stick to like-for-like replacement for simplest compliance and warranty

For Nissan Dayz engine replacement in the UK, you'll need your V5C logbook, proof of purchase/invoice, warranty certificate, and updated engine number documentation for DVLA records if the replacement engine has a different serial number.

• Keep supplier invoice showing engine code and chassis compatibility
• Warranty certificate required for future claims and insurance proof
• Update DVLA if engine number changes (rare for like-for-like swaps)
• MOT testers may request documentation for emissions compliance verification
