Will it fit? BMW 8 Series (E31 and G15) engine questions
Engine swap questions for the BMW 8 Series (E31 and G15)
Owners often ask whether a more powerful engine from another BMW 8 Series (E31 and G15) model can be fitted. These answers show what each upgrade involves.
Can I fit the M73B54 from the E31 850Ci into an E31 850i?
It is possible, and it is one of the more common upgrades. Both engines are petrol V12 units, so the engine bay and mounting points are similar, but the M73B54 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 26 hp and 40 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the M73B54 from the E31 850Ci into an E31 840i?
It is a conversion rather than a replacement. The M73B54 is a V12 and the M60B40 a V8, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 40 hp and 90 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the M70B50 from the E31 850i into an E31 840i?
It is a conversion rather than a replacement. The M70B50 is a V12 and the M60B40 a V8, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 14 hp and 50 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the M73B54 from the E31 850Ci into an E31 840Ci?
It is a conversion rather than a replacement. The M73B54 is a V12 and the M62B44 a V8, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 40 hp and 70 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the M70B50 from the E31 850i into an E31 840Ci?
It is a conversion rather than a replacement. The M70B50 is a V12 and the M62B44 a V8, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 14 hp and 30 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Fitment and swap notes for the BMW 8 Series (E31 and G15)
- The 850CSi uses the S70B56.
Engines from the same family usually share mounts and gearbox bolt patterns, but wiring, ECU, sump and cooling differ between versions. Moving to a different family is a conversion, not a replacement.
M70 and M73: Few tuning options exist. Owners keep the V12 standard.
M60: Tuning gains are small. Most owners who want more torque fit an M62B44 in place of an M60B40, using the M62 wiring and management.
M70 and M73: Few tuning options exist. Owners keep the V12 standard.
M62: Supercharger kits exist for the M62 and the 4.6is is a popular upgrade for X5 owners. Most buyers fit a standard engine to restore a car rather than to tune it.
Known problems by engine in the BMW 8 Series (E31 and G15)
M70 and M73
- Wiring harness. Inspect the harness near the heads.
- Cooling. Pressure-test the system.
- Dual engine management. Read both ECUs for fault codes.
- Fuel system. Check fuel pressure.
M60
- Nikasil bore damage. A cold and hot compression test or a leak-down test on all eight cylinders is the only reliable check.
- Timing chain guides and tensioners. Listen for a rattle on a cold start, especially from the front of either bank.
- Coolant leaks in the valley. Look at the back of the engine for coolant trails and pressure-test the system.
- Valve cover and spark plug tube gaskets. Pull a coil and check the well for oil.
- Engine wiring harness. Flex the harness gently and look for cracked insulation near the heads.
M70 and M73
- Wiring harness. Inspect the harness near the heads.
- Cooling. Pressure-test the system.
- Dual engine management. Read both ECUs for fault codes.
- Fuel system. Check fuel pressure.
M62
- Timing chain guides. Remove the valve covers and inspect the upper guides; replace all guides when fitting a used engine.
- Valve stem seals. Watch the exhaust after a cold start and after a long idle.
- Valley coolant pipe. Look for coolant at the back of the engine and pressure-test the system.
- Water pump and thermostat. Look for coolant trails at the front of the engine.
- VANOS (M62TU). Read the VANOS fault memory.
How to identify the right engine for your BMW 8 Series (E31 and G15)
Start with the VIN. The last seven characters identify your car in BMW's systems, and from them we can confirm the engine code, the production date, the gearbox and whether the car has xDrive. That is the only reliable way to order.
Next, check the stamp on the block. On most BMW four- and six-cylinder engines it sits on the left side of the block below the intake; on V engines it is usually at the back near the gearbox. The stamp shows the engine code and serial number.
Finally, compare the ancillaries. Two engines with the same code can carry different turbos, injectors, manifolds or sensors depending on the model and market. Our listings show what is fitted to each unit.
BMW 8 Series (E31 and G15) engine prices
Our BMW 8 Series (E31 and G15) engine stock runs to 4 units, priced from 3.476,00 € to 5.635,00 € with a median of 4.904,00 €.
Prices depend on the exact version, the donor's mileage, how complete the engine is and the demand for that code. Higher-output versions, low mileage and dressed engines with turbo, injectors and ancillaries cost more; long blocks and higher mileage cost less.
BMW 8 Series (E31 and G15) engine prices by model year
| Model years | Units | From | Median | To |
|---|---|---|---|---|
| 2015–2019 | 2 | 4.422,00 € | 4.904,00 € | 4.904,00 € |
| 2020–2024 | 2 | 3.476,00 € | 5.635,00 € | 5.635,00 € |
Engines from 2015–2019 have a median of 4.904,00 €, while units from 2020–2024 sit at 5.635,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

Buying checklist for a BMW 8 Series (E31 and G15) engine
- Confirm the exact engine code. Read the code stamped on the block and compare it with the code for your car. Send us the last seven characters of the VIN and we confirm the match before anything is paid.
- 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.
- 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.
- 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.
- Photographs from every side. Good suppliers photograph the actual engine you will receive. Look for the block stamp, the sump, the timing cover and any broken brackets or connectors in the pictures.
- 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.
- 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.
- Gearbox and flywheel match. Manual and automatic engines differ at the flywheel or flexplate, and sometimes at the crankshaft spigot. Make sure the engine you buy matches your gearbox or that you transfer the right parts.
- Warranty terms in writing. Read what the warranty covers, how long it runs and what fitting conditions apply. Most warranties require a qualified workshop, new fluids and filters, and replacement of the cooling parts that caused the original failure.
- Why your old engine failed. Before fitting a replacement, find out why the original failed. An overheating radiator, a blocked intercooler or a failed turbo can destroy a second engine if they are not fixed.
- 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.
- VANOS operation. Rough idle, a rattle from the front of the head and a loss of torque at low revs point to VANOS seals or solenoids. These are serviceable parts and are easier to renew with the engine out.
- Bore coating. Early engines with Nikasil bores can be damaged by high-sulphur fuel. A compression or leak-down test is the only reliable check; units with Alusil or iron bores are not affected.
- Originality and numbers. For collectible cars, the engine number and correct ancillaries add value. Photograph the stamp and keep it with the car's documents.
- Both cylinder banks. On a V engine, check compression, plugs and coils on both banks. Faults on one bank alone are common and easy to miss on a quick test.
- 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.
Fitting an engine to your BMW 8 Series (E31 and G15)
- Compare the engines side by side. Put the replacement next to the old engine and compare sensors, brackets, connectors, the sump, the starter and the flywheel or flexplate. Note anything that must be transferred.
- Transfer the parts that differ. Move the parts that are specific to your car, such as the engine harness on some models, the sump on xDrive cars or the air conditioning compressor bracket. Use new seals and gaskets for everything you move.
- Replace the rear main seal and drive parts. With the engine out, the rear crankshaft seal is easy to reach. Fit a new one, inspect the flywheel and clutch on manual cars or the converter seal on automatics.
- Renew the cooling system. Most engine failures start with cooling. Fit a new water pump, thermostat and hoses, check the radiator and fan, and use the correct coolant.
- Fit new engine mounts. Old mounts transfer vibration and can let the engine move enough to damage hoses. They are cheap and easy to replace with the engine out.
- 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.
- Clean the intake. If the old engine failed internally, debris can be in the intake or intercooler. Clean them so nothing reaches the new engine.
- 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.
- Reset VANOS adaptations. Clear the VANOS adaptations so the ECU learns the camshaft positions of the new engine.
- 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.
Diagnosing engine trouble in a BMW 8 Series (E31 and G15)
If your current engine is showing one of these symptoms, this table helps you judge whether it can be repaired or whether a replacement engine is the better route.
| Symptom | Likely cause |
|---|---|
| Knocking from the bottom of the engine | A deep knock that rises with engine speed usually means worn rod or main bearings. |
| Overheating or losing coolant | Coolant loss without visible leaks points to a head gasket or a cracked head; visible leaks point to the water pump, hoses, thermostat housing or expansion tank. |
| White smoke that smells sweet | Coolant burning in the cylinders, from a head gasket, a cracked head or, on diesels, a leaking EGR cooler. |
| Blue smoke | Oil burning in the cylinders. |
| Rough idle or misfire | Ignition coils, spark plugs, injectors and vacuum leaks are the usual causes. |
| Loss of power | Start with the simple things: air filter, boost leaks on turbo engines, fuel pressure and fault codes. |
| Rattle for a few seconds after a cold start | The classic sign of a weak timing chain tensioner or stretched chain. |
| Poor low-down torque and uneven idle | VANOS seals or solenoids. |
| Hard starting when warm and low compression | On engines with Nikasil bores, the bore coating may be damaged. |
Knocking from the bottom of the engine. A deep knock that rises with engine speed usually means worn rod or main bearings. Stop driving: bearing failure ends with a broken connecting rod. A used engine is normally the most economical fix once the bottom end is damaged.
Overheating or losing coolant. Coolant loss without visible leaks points to a head gasket or a cracked head; visible leaks point to the water pump, hoses, thermostat housing or expansion tank. Overheating should be fixed before it warps the head.
White smoke that smells sweet. Coolant burning in the cylinders, from a head gasket, a cracked head or, on diesels, a leaking EGR cooler. Check the coolant level and look for oil in the coolant.
Blue smoke. Oil burning in the cylinders. A puff on start-up points to valve stem seals; constant smoke under load points to piston rings or, on turbo engines, turbo seals.
Rough idle or misfire. Ignition coils, spark plugs, injectors and vacuum leaks are the usual causes. A misfire on one cylinder that moves when you swap coils is a coil; one that stays is a plug, injector or compression problem.
Loss of power. Start with the simple things: air filter, boost leaks on turbo engines, fuel pressure and fault codes. A gradual loss with poor compression on a test points to internal wear.
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.
Poor low-down torque and uneven idle. VANOS seals or solenoids. The engine may run well at high revs but feel flat and lumpy at low speed.
Hard starting when warm and low compression. On engines with Nikasil bores, the bore coating may be damaged. A leak-down test confirms it.
Repair or replace the engine in your BMW 8 Series (E31 and G15)?
As a rule, bolt-on faults are worth repairing and internal damage is not. Seals, sensors, coils, injectors, pumps and turbos can be replaced in the car. Once the bearings, crankshaft, bores or head of an engine are damaged, a used engine is usually cheaper and quicker than a rebuild.
Ask your workshop for a written diagnosis before deciding. A compression test, an oil analysis and a borescope inspection take an hour or two and remove most of the guesswork.

What should I replace when I fit a used M62B35 engine?
A used engine lasts longest when it starts life in your car with fresh fluids and new seals. Fit a new oil filter and fresh oil of the grade BMW lists for this engine, and refill the coolant with the correct BMW antifreeze mix. Change the drive belt, the thermostat and the water pump seals if they look tired, because they are cheap while the engine is out. Use new gaskets for the exhaust manifold, the intake and the sump plug, and check every hose clip before the first start.
Look at the engine mounts and the clutch or the torque converter while the engine is out. Old mounts can crack a new engine's brackets, and a worn clutch is much easier to change now.
Before the first start, turn the engine over without fuel until the oil pressure light goes out. Then let it idle, check for leaks, and drive gently for the first few hundred kilometres.
The warranty asks for fitting by a qualified mechanic and the correct oil, coolant and filters. Keep your receipts in case you ever need to make a claim.

Are there other versions of the BMW M70B50?
In our yard the M70B50 is the only listed version of the M70 family. It makes 220 kW (300 HP) and 450 Nm, and was built from 1987 to 1994.
Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.
This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.

Is the BMW M62B44 a diesel or petrol engine?
The M62B44 is a petrol engine. It is a 4.4 liter (4,398 cc) V8, DOHC, 32 valve unit with no turbo (naturally aspirated), and it was built to the Euro 3 emission standard.
