Rolls Royce Ghost Series II N74B66 V12 Specialist Engine ReplacementCompare Quotes

A rebuilt Rolls Royce Ghost Series II N74B66TU engine typically costs £15,000-£35,000 supply-only in the UK, with Black Badge and late-calibration variants at the higher end due to performance components and OPF compatibility requirements.

• Standard Wheelbase rebuilt: £15,000-£32,000 typical range
• Black Badge performance rebuilt: £18,000-£40,000 typical range
• Supply & fit adds £3,500-£7,500 depending on specialist location
• All EngineMarket quotes include minimum 12-month unlimited mileage warranty

All Rolls Royce Ghost Series II models (2014-2020) use the N74B66TU twin-turbo V12 family, with suffix variants N74B66TU-A (2014-2016) and N74B66TU-B (2017-2020, Black Badge) denoting calibration updates.

• N74B66TU is the base code for all Ghost Series II variants
• N74B66TU-A: early calibration, pre-upgraded turbo oil feed design
• N74B66TU-B: late calibration, OPF-compatible, Black Badge performance mapping
• Enter your registration above to verify exact code for your vehicle

Yes, when sourced from vetted UK specialists who compression-test, update known failure points like valve stem seals, and provide a minimum 12-month unlimited mileage warranty on rebuilt N74B66TU engines.

• Reconditioned N74B66TU engines undergo strip-down inspection and component renewal
• Upgraded turbo oil feed lines prevent recurrence of coking failures
• Compression and leak-down testing ensures factory-spec performance
• Warranty terms vary; confirm unlimited mileage coverage before purchase

Turbo failure on the N74B66TU is most commonly caused by oil feed line coking, where carbon deposits restrict lubrication flow to turbo bearings, typically occurring between 60,000-90,000 miles on short-journey usage patterns.

• Carbon buildup in narrow oil feed lines restricts turbo lubrication
• Short journeys prevent oil reaching optimal temperature, accelerating coking
• Upgraded braided stainless steel feed lines prevent recurrence during rebuild
• Preventative line replacement at 50k miles avoids costly turbo failure

Excessive oil consumption on the N74B66TU is typically caused by hardened valve stem seals allowing oil into combustion chambers, producing blue smoke on startup and increasing consumption beyond 1 litre per 1,000 miles.

• Original seals harden with age and heat cycles beyond 70k miles
• Blue smoke on cold startup is the classic symptom of seal wear
• Rebuilt engines include updated Viton seals addressing this failure point
• Top-end seal replacement is viable under 90k miles; rebuilt engine preferred beyond

Yes, but verify compression test results, mileage history, and calibration suffix match before purchase; used N74B66TU engines offer budget options but carry higher risk than rebuilt units with warranty protection.

• Request compression and leak-down test documentation before purchase
• Confirm calibration suffix (A vs B) matches your vehicle's ECU requirements
• Low-mileage donor engines from accident write-offs offer best value
• Basic warranty typically 3 months; upgrade options may be available

No, the Ghost Series II N74B66TU Technical Update engine is not directly interchangeable with the pre-facelift Series I N74B66 due to revised turbo calibration, Valvetronic mapping, and ECU compatibility requirements.

• N74B66TU features updated turbo control strategy versus N74B66
• ECU coding and immobiliser sync require exact calibration match
• Physical mounting points are similar but electronics prevent cross-fitment
• Always verify engine code via registration lookup before ordering replacement
