Engine swap questions for the BMW E34 5 Series
Owners often ask whether a more powerful engine from another BMW E34 5 Series model can be fitted. These answers show what each upgrade involves.
Can I fit the S38B35 from the E34 M5 3.5 into an E34 520i?
It is possible, and it is one of the more common upgrades. Both engines are petrol inline-6 units, so the engine bay and mounting points are similar, but the S38B35 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 110 hp and 140 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the M30B35 from the E34 535i into an E34 520i?
It is possible, and it is one of the more common upgrades. Both engines are petrol inline-6 units, so the engine bay and mounting points are similar, but the M30B35 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 61 hp and 115 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 E34 5 Series
- The 540i and 530i V8s use the M60 with Nikasil bores; a compression test is essential.
- The M5 uses the S38B36 or S38B38; matching numbers matter.
- M50 sixes replaced M20s from 1990.
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.
M20: The classic upgrade is the M20 'stroker': a 2.7 eta block and crank with a 885 head from a 325i, giving more torque without losing the rev range. Chip tuning on Motronic cars and a free-flowing exhaust add modest gains.
M40: There is little to gain from tuning an M40. Owners who want more power usually move to an M42 or M44, or swap to a six-cylinder.
M30: M30 owners often fit a 3.5 litre unit in place of a 2.8 or 3.0, or build a turbocharged M30 using the strong bottom end. Head work and cam upgrades suit naturally aspirated builds.
M88 and S38: Builders fit S38B38 cranks into 3.6 litre engines, and many E30 or E34 projects use an S38 with motorsport camshafts. Keep receipts; buyers expect them.
M50: Popular moves are an M50 manifold on M52 or S52 engines, a remap and a 2.8 litre stroker using an M52B28 crank. For E30 owners, an M50 swap is one of the most documented upgrades.
M51: Few tuning options exist.
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.
M43: The M43 is an economy engine. Tuning gains are small; buyers wanting performance usually choose an M44 or a six-cylinder swap.
Known problems by engine in the BMW E34 5 Series
M20
- Timing belt failure. Ask for the date of the last belt and tensioner change. If there is no record, treat it as due.
- Cylinder head cracks. Pressure-test the cooling system and look for cracks when the cam cover is off.
- Rocker arm and shaft wear. Inspect rockers and clips with the cam cover removed.
- Oil spray bar and cam wear. Check the spray bar banjo bolts are tight and the holes clear.
- Water pump and thermostat. Look for coolant trails below the pump and on the belt cover.
M40
- Timing belt. Look for a dated belt sticker or invoice.
- Camshaft lobe wear. Remove the cam cover and inspect the lobes.
- Rocker arms. Listen at idle with the oil hot.
- Cooling and thermostat. Check the hoses for swelling and the radiator tanks for cracks.
M30
- Head gasket and cracked heads. Do a compression test and look for bubbles in the expansion tank with the engine running.
- Cooling system age. Check the fan clutch resistance hot and the radiator for blocked cores.
- Rocker arm wear. Inspect the cam surface with the valve cover off.
- Timing chain tensioner. Listen for a cold-start rattle at the front of the engine.
- Oil pressure sender and leaks. Check for oil around the filter housing and the bellhousing.
M88 and S38
- Valve clearances. Ask for the last clearance check.
- Timing chain guides. Listen for start-up rattle at the front.
- Oil pump drive nut. Ask if the oil pump nut has been secured.
- Throttle bodies and sensors. Check for smooth idle and even cylinder balance.
M50
- Cooling system. Check for a metal impeller water pump and a recent expansion tank.
- VANOS seals (M50TU). Listen for a rattle at the front of the head at idle and check for a flat spot below 3,000 rpm.
- Crankcase ventilation valve. Check for oil in the intake boot and around the dipstick tube.
- Oil filter housing gasket. Look for oil on the alternator side of the engine.
- Valve cover gasket. Remove a coil and inspect the well.
M51
- Injection pump. Check for smoke and starting problems.
- Head cracks. Pressure-test the system.
- Turbocharger. Look for smoke.
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.
M43
- Timing chain guide rail. Remove the valve cover and inspect the top of the guide; replace it when fitting any used M43.
- Valve cover gasket leaks. Look for burnt oil on the exhaust side.
- Ticking hydraulic lifters. Listen after the engine has warmed; noise that stays is a lifter problem.
- Engine mounts and vibration. Check mounts for split rubber when the engine is in the car.
How to identify the right engine for your BMW E34 5 Series
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 E34 5 Series engine prices
Our BMW E34 5 Series engine stock runs to 33 units, priced from 928,00 € to 11.942,00 € with a median of 9.014,00 €.
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.

Buying checklist for a BMW E34 5 Series 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.
- Turbocharger shaft play and oil. Rotate the compressor wheel by hand. A small amount of side play is normal; in-and-out play or wheel contact with the housing is not. Oil pooled in the intake or intercooler pipes points to worn seals.
- Injector correction values. On a diesel that can be run before removal, the injector correction values show whether one injector is delivering more or less fuel than the others. Large deviations mean an injector is on its way out.
- 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.
- Timing belt history. A timing belt must be changed on time and distance. With no dated record, treat the belt, tensioner and water pump as due and replace them before the first start.
- 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.
- Bearing and valve clearance history. M engines are built to tighter tolerances. Ask for the last rod bearing replacement and valve clearance check, and consider an oil analysis if the engine can be run.
- 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.
- Plastic cooling parts. Expansion tanks, thermostat housings and water pump impellers made of plastic crack with age. Plan to replace them when the engine is fitted.
Fitting an engine to your BMW E34 5 Series
- 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.
- Fit a new timing belt kit. Fit a new belt, tensioner and water pump and set the timing with the correct tools before the first start.
- Prepare the turbo. Fit new oil feed and return seals, clean the intercooler and pipes of any oil or debris from the old engine, and prime the turbo with oil before starting.
- Code the injectors and bleed the fuel. Enter the injector correction codes into the ECU, check the glow plugs and bleed the fuel system so the engine does not crank dry.
- 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 E34 5 Series
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. |
| Whistle, loss of boost or limp mode | A split charge pipe, a sticking wastegate or worn turbo bearings. |
| Black smoke under acceleration | Too much fuel for the air available: boost leaks, a sticking EGR valve, a dirty air mass meter or a leaking injector. |
| Hard starting when cold | Glow plugs or the glow plug control unit. |
| Poor low-down torque and uneven idle | VANOS seals or solenoids. |
| Engine stops suddenly and will not restart | On belt-driven engines, a snapped timing belt. |
| Hard starting when warm and low compression | On engines with Nikasil bores, the bore coating may be damaged. |
| Oil pressure warning or bearing noise at high revs | On M engines, a warning at high revs can be the first sign of bearing wear. |
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.
Whistle, loss of boost or limp mode. A split charge pipe, a sticking wastegate or worn turbo bearings. Check the pipes first, then the turbo shaft for play.
Black smoke under acceleration. Too much fuel for the air available: boost leaks, a sticking EGR valve, a dirty air mass meter or a leaking injector.
Hard starting when cold. Glow plugs or the glow plug control unit. On older diesels, also check the injection pump and fuel lines for air leaks.
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.
Engine stops suddenly and will not restart. On belt-driven engines, a snapped timing belt. Do not keep cranking: on an interference engine the valves are probably already bent.
Hard starting when warm and low compression. On engines with Nikasil bores, the bore coating may be damaged. A leak-down test confirms it.
Oil pressure warning or bearing noise at high revs. On M engines, a warning at high revs can be the first sign of bearing wear. Check the oil level and stop driving hard until it is diagnosed.
Repair or replace the engine in your BMW E34 5 Series?
Repair makes sense when the fault is outside the engine or in a part that can be replaced without opening it: sensors, coils, injectors, gaskets, the water pump or a turbo. Replacement makes sense when the bottom end, the crankshaft, the bores or the head are damaged, because rebuilding an engine properly costs more than a good used unit.
M engines are expensive to rebuild because parts are costly and specialist labour is needed. A used M engine with documented bearings is often the better value for road cars.
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.
