Nissan Lafesta Engine ReplacementCompare Prices & Save

Nissan Lafesta models use petrol engines only: QR20DE/QR18DE port-injection (2004-2011 M11/M12) or MR20DDT/MR18DDT direct-injection turbo (2011-2018 B35). No diesel variants were ever sold.

• M11/M12: QR20DE 2.0L or QR18DE 1.8L port-injection petrol
• B35: MR20DDT 2.0L or MR18DDT 1.8L direct-injection turbo petrol
• All variants use CVT automatic transmission
• Engine code is stamped on block; check near oil filter housing

Rebuilt QR20DE engines for M11/M12 Lafesta typically cost £950-£2,400 supply-only in the UK, with supply & fit adding £450-£950 depending on location and workshop.

• Rebuilt units include upgraded timing tensioner (OEM 13075-8H300)
• Used engines from £650 but verify compression and history
• Supply & fit service recommended for CVT ECU mapping
• 12-month warranty standard on rebuilt/reconditioned units

QR20DE engines are robust but suffer documented timing chain tensioner failure; MR-series B35 engines are efficient but require intake valve cleaning. Regular maintenance prevents most issues.

• QR20DE: Replace timing chain kit preventatively at 60k miles
• MR-series: Walnut shell clean intake valves every 40k miles
• Oil changes every 5k miles critical for longevity
• CVT fluid service prevents transmission-related complaints

Yes, QR20DE engines from Primera P12, X-Trail T30 and Note share fitment with M11/M12 Lafesta; B35 MR-series engines have more limited cross-compatibility. Always verify ECU/CVT mapping.

• QR20DE from Primera P12 (2002-2007) is direct swap for M11/M12
• Mounting points and wiring harness compatible on QR-series
• B35 MR20DDT has limited donor options; specialist sourcing advised
• CVT-equipped Lafestas require ECU reprogramming after swap

QR20DE timing chain failure stems from weak factory tensioner design allowing chain stretch; Nissan issued TSBs acknowledging the issue. Failure typically occurs 60k-100k miles.

• Factory tensioner lacks sufficient damping for long-term use
• Chain stretch causes rattling, then jumped timing
• Low oil levels or infrequent changes accelerate wear
• Upgraded tensioner (13075-8H300) prevents recurrence

All Nissan Lafesta models sold in the UK are petrol-only. No diesel variant was ever produced for any market, eliminating DPF or diesel-specific concerns for import owners.

• Lafesta was designed as a compact petrol MPV for Japan
• QR and MR engine families are petrol-only architectures
• No AdBlue, DPF or diesel emissions systems to maintain
• Petrol engines simpler to source and rebuild in UK

With proper maintenance, QR20DE engines can exceed 150k miles; MR-series B35 units are newer so long-term data is limited but 120k+ miles is achievable with valve cleaning.

• QR20DE: Replace timing kit at 60k, oil pump inspection at 80k
• MR-series: Intake valve cleaning every 40k miles essential
• Full service history and quality oil critical for longevity
• Rebuilt engines with upgraded components can match new-engine life

Yes, QR20DE is straightforward to rebuild; most UK specialists offer rebuilt units with upgraded timing components for £950-£2,400, often better value than repair after major failure.

• Rebuild addresses timing chain, oil pump and bearing wear
• Upgraded tensioner (13075-8H300) prevents repeat failure
• Bench testing ensures reliability before installation
• 12-month warranty provides peace of mind vs DIY repair

EngineMarket connects you with vetted UK specialists supplying rebuilt, reconditioned and used Lafesta engines nationwide, with price comparison, warranty protection and CVT mapping support.

• Network includes JDM import specialists familiar with Lafesta
• All suppliers offer minimum 12-month unlimited mileage warranty
• Supply-only or full supply & fit options available
• Registration lookup ensures exact engine code match

CVT issues are often misdiagnosed as engine problems; proper ECU mapping after engine replacement is critical. Judder or limp mode usually indicates transmission, not engine, fault.

• CVT fluid service every 40k miles prevents judder
• Engine swaps require specialist ECU reprogramming
• Transmission faults can trigger check engine light
• Use Lafesta-specialist workshops for CVT-integrated repairs
