Which engine is in your 760i?
| Engine code | Built | Power | Torque | Type |
|---|---|---|---|---|
| N73B60 | 2003–2008 | 445 hp | 600 Nm | 6.0 L petrol V12, naturally aspirated |
N73B60 in the 760i
The N73B60 was used in the E66 760i, built 2003–2008. It is a 6.0 L naturally aspirated petrol V12 with 445 hp and 600 Nm.
Reading the code: N marks an N-series code, the generation of BMW engines introduced from 2001; 73 is the family number; B stands for petrol (from the German Benzin); 60 is the capacity in decilitres, so 6.0 litres.
760i engines by model year
| Model year | Engine |
|---|---|
| 2003 | N73B60 (445 hp) |
| 2004 | N73B60 (445 hp) |
| 2005 | N73B60 (445 hp) |
| 2006 | N73B60 (445 hp) |
| 2007 | N73B60 (445 hp) |
| 2008 | N73B60 (445 hp) |
The 760i kept the same engine for the whole E66 run, which makes ordering simple: any unit with the same code fits, subject to the gearbox, drive type and sump.
Other cars with the same engine as the 760i
A replacement engine does not have to come from another 760i. These models left the factory with the same engine code, so a unit from any of them is a candidate donor once the sump, mounts and ancillaries are matched to your car.
N73B60: BMW E65 760Li.
How to confirm your engine code
The 760i only used the N73B60, but the exact version can still change with the build date, gearbox and market. Send us the last seven characters of the VIN and we read the engine code from BMW's records, or look for the code stamped on the block. How to find your BMW engine code.
Known 760i engine problems
The N73B60 in the 760i shares the known weak points of the N73 and N74 family. Full N73 and N74 guide.
| Known fault | What to check |
|---|---|
| Ignition coils and spark plugs | Read misfire counters. |
| Injectors | Read injector corrections. |
| Coolant leaks | Pressure-test the system. |
| Turbo oil lines (N74) | Look for oil smoke. |
Ignition coils and spark plugs. Coils fail and cause misfires.
Injectors. Injectors fail and cause misfires.
Coolant leaks. Coolant pipes and hoses leak because of heat in the V.
Turbo oil lines (N74). Oil lines to the turbos leak.
Symptoms to watch for on the 760i
Rattle for a few seconds after a cold start. The classic sign of a weak timing chain tensioner or stretched chain. It must be checked quickly: a chain that jumps a tooth can bend valves.
Long cranking before the engine starts. On direct-injection engines, a weak high-pressure fuel pump or leaking injector lets pressure drop when the engine is off.
Looking after the 760i engine
- Oil: 5W-30 BMW Longlife-01.
- Service interval: Oil every 10,000 km.
- Timing drive: Timing chains, one per bank.
- Workshop notes: Check whether the engine is BMW or Rolls-Royce specification before ordering.
Buying a used engine for the 760i: checklist
- Sump, oil pickup and drive variants. Rear-drive, xDrive and front-drive cars can use different sumps, oil pickups and engine mounts even with the same engine code. Check that the sump matches your subframe and front axle.
- Compression or leak-down figures. Even compression across all cylinders tells you more than mileage. Ask for the figures, not just a pass or fail, and compare the highest and lowest readings: a spread above 10 to 15 percent deserves a question.
- Ask how the donor car was damaged. Most good used engines come from cars with body damage. A front-end impact can crack sensors, the timing cover or the sump; a rear or side impact usually leaves the engine untouched. The yard records the damage on each unit.
- List of what is fitted. Engines are sold with different ancillaries: some have the turbo, injectors, manifolds, alternator and starter, others are long blocks. Agree the list in writing so you know which parts must come from your old engine.
- Look at the oil and coolant. Clean oil without metal particles and coolant without oil are good signs. Milky oil, oily coolant or a burnt smell mean the engine needs further checks before it is fitted.
- Timing chain noise. Listen for a rattle at the front of the engine for the first seconds after a cold start. On an engine that cannot be run, look at the chain guides through the oil filler or with the valve cover off.
- Injectors and high-pressure fuel pump. Direct-injection engines rely on high-pressure pumps and precise injectors. Ask whether the injectors are original or updated and whether there were fuel pressure faults.
- Both cylinder banks and both ECUs. V12 engines often use separate management for each bank. Read faults from both and compare compression across all twelve cylinders.
BMW 760i replacement engine cost
We do not have a 760i engine on the shelf at the moment. Send us your VIN or the code you need and the desk will tell you when the next unit arrives and what it will cost.
On top of the engine, budget for the workshop's labour and the parts that are best replaced while the engine is out: engine mounts, the rear main seal, cooling parts, a clutch or converter seal, fluids and filters.
Will it fit my 760i?
Will the N73B60 fit my BMW E66 760i?
Yes, the BMW E66 760i left the factory with the N73B60, so an N73B60 from another car is the direct replacement. The fourth 7 Series long-wheelbase was built 2001–2008, and the N73B60 was produced 2003–2008, so check that your car's build date falls inside that window. Confirm the drive type (rear-drive or xDrive), the gearbox (manual or automatic) and the emissions standard, because these can change the sump, the flywheel and the software. Send us the VIN and we check all of it for you.

Fitting a replacement engine in the 760i
- Inspect or replace the timing chain parts. Look at the guides and tensioner. On high-mileage engines, replacing them now costs far less than doing it later.
- Fill with the right oil and prime it. Fill with new oil of the correct specification and a new filter. Crank with the fuel and ignition disabled until oil pressure builds.
- Coding and adaptations. On modern BMWs, the engine ECU must be matched to the car's immobiliser (CAS, FEM or BDC). Reset adaptations, register the battery and clear faults with diagnostic software.
- First start and leak check. Start the engine, let it idle and watch oil pressure, temperature and fault codes. Check for leaks and bleed the cooling system.
- First 1,000 km. Drive gently for the first few hundred kilometres, vary the engine speed and avoid full load. Change the oil and filter after about 1,000 km to remove any assembly debris.
