Engine swap questions for the BMW E90, E91, E92 and E93 3 Series
Owners often ask whether a more powerful engine from another BMW E90, E91, E92 and E93 3 Series model can be fitted. These answers show what each upgrade involves.
Can I fit the N47D20C from the E90 318d into an E90 316i?
It is a full conversion: the N47D20C runs on diesel and the N46B18 on petrol, so the fuel system, wiring, ECU, instrument coding and usually the gearbox change too. The gain is 28 hp and 145 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the M57D30TU2 from the E90 335d into an E90 316i?
It is a full conversion: the M57D30TU2 runs on diesel and the N46B18 on petrol, so the fuel system, wiring, ECU, instrument coding and usually the gearbox change too. The gain is 171 hp and 405 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the S65B40 from the E90 M3 into an E90 318i?
It is a conversion rather than a replacement. The S65B40 is a V8 and the N46B20 an inline-4, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 270 hp and 200 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the S65B40 from the E92 M3 into an E90 318i?
It is a conversion rather than a replacement. The S65B40 is a V8 and the N46B20 an inline-4, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 270 hp and 200 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the N51B30 from the E90 328i into an E90 325i?
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 N51B30 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 12 hp and 20 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the M57D30TU2 from the E90 335d into an E90 325i?
It is a full conversion: the M57D30TU2 runs on diesel and the N52B25 on petrol, so the fuel system, wiring, ECU, instrument coding and usually the gearbox change too. The gain is 68 hp and 330 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the N54B30 from the E90 335i into an E90 330i?
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 N54B30 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 34 hp and 80 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the N54B30 from the E92 335i into an E90 330i?
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 N54B30 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust.

Can I fit the M57D30TU2 from the E90 335d into an E90 320si?
It is a full conversion: the M57D30TU2 runs on diesel and the N45B20S on petrol, so the fuel system, wiring, ECU, instrument coding and usually the gearbox change too. The gain is 113 hp and 380 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.
Can I fit the N53B25 from the E90 523i into an E90 320si?
It is a conversion rather than a replacement. The N53B25 is an inline-6 and the N45B20S an inline-4, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 17 hp and 40 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 E90, E91, E92 and E93 3 Series
- Pre-LCI (to 2008 or 2010 depending on body) and LCI cars use different engines and electronics in some models.
- The 335i moved from the N54 twin-turbo to the N55 single-turbo with the LCI.
- N47 diesels in 318d and 320d are the most commonly replaced engines; check the chain on any used unit.
- N53 engines were not sold in the US; US cars use the N52 or N51.
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.
N42 and N46: Tuning potential is limited. Most owners looking for more power choose a six-cylinder swap.
N42 and N46: Tuning potential is limited. Most owners looking for more power choose a six-cylinder swap.
N52: Gains come from intake and exhaust work and a remap. Owners wanting more usually move to an N54 or N55 swap.
N52: Gains come from intake and exhaust work and a remap. Owners wanting more usually move to an N54 or N55 swap.
M57: Remaps add around 50 hp. The M57 is one of the best diesel conversion engines.
N54: The N54 responds strongly to remaps and bigger turbos. Well-built examples exceed 500 hp with upgraded fuelling.
N47: Remaps add around 30 hp; check the chain first.
N43: Gains are small. The N43 is for economy and originality.
N53: Modest gains; the N53 is chosen for originality and economy.
S65: Headers, exhausts and remaps add modest power. Supercharger kits exist but most owners keep the S65 standard.

How to identify the right engine for your BMW E90, E91, E92 and E93 3 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 E90, E91, E92 and E93 3 Series engine prices
Across 654 BMW E90, E91, E92 and E93 3 Series engine units in our stock today, prices start at 601,00 € and reach 14.608,00 €. The median — the price in the middle of the range — is 2.715,00 €.
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 E90, E91, E92 and E93 3 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.
- Particulate filter and EGR history. Short-trip diesels clog their DPF and EGR systems. The engine may be fine, but ask whether the donor car had DPF warnings, and plan to clean or check your own filter before fitting.
- Swirl flaps. Check whether the swirl flaps are in place, blanked or removed. Broken swirl flaps are a known cause of engine failure on several BMW diesels, so many owners fit blanking plates when the intake is off.
- 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.
- Gearbox-end timing chain. On this engine the timing chain sits at the gearbox end, so replacing it normally means removing the engine. If the chain has not been replaced, the time to do it is before the engine goes into your car.
- 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.
- Double VANOS units and solenoids. Ask for the adaptation values or fault history if the engine was running. Solenoids are inexpensive and are often replaced as a matter of course on a used engine.
- Valvetronic motor and eccentric shaft sensor. The Valvetronic motor and its sensor cause limp-mode faults when they fail. Inspect the connector and the seal around the motor for oil.
- 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.
- 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.
- 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.
- Electric water pump. This engine uses an electric water pump. It fails without warning and needs a diagnostic bleeding routine when it is replaced or the system is refilled.
Fitting an engine to your BMW E90, E91, E92 and E93 3 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.
- Replace the rear timing chain if in doubt. On engines with the chain at the gearbox end, chain work needs the engine out. If the history is unknown, replace the chain, guides and tensioner before fitting.
- 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.
- Check the particulate filter. If the old engine failed with oil or coolant entering the exhaust, the DPF may be contaminated. Check its back-pressure before relying on it.
- 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.
- Teach the Valvetronic limit stops. Run the Valvetronic learning routine so the ECU knows the eccentric shaft limits.
- 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 E90, E91, E92 and E93 3 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. |
| Rattle or whine from the gearbox end | On engines with the timing chain at the rear, a rattle or whine from the back of the engine is the warning sign of chain stretch or guide wear. |
| 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. |
| Particulate filter warning | Short trips stop the DPF from regenerating. |
| Sudden metallic noise followed by misfire | On diesels with swirl flaps, a broken flap or screw can enter a cylinder. |
| Poor low-down torque and uneven idle | VANOS seals or solenoids. |
| Limp mode with a Valvetronic fault | The Valvetronic motor, its eccentric shaft sensor or the wiring. |
| 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. |
| 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.
Rattle or whine from the gearbox end. On engines with the timing chain at the rear, a rattle or whine from the back of the engine is the warning sign of chain stretch or guide wear.
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.
Particulate filter warning. Short trips stop the DPF from regenerating. A long motorway run often clears it; a filter that keeps blocking may be covering an injector, EGR or turbo problem.
Sudden metallic noise followed by misfire. On diesels with swirl flaps, a broken flap or screw can enter a cylinder. Stop the engine immediately; continued running usually destroys the piston and head.
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.
Limp mode with a Valvetronic fault. The Valvetronic motor, its eccentric shaft sensor or the wiring. The engine runs on a reduced throttle until it is repaired.
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.
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 E90, E91, E92 and E93 3 Series?
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.
Timing chain work on the engine needs the engine removed. When the chain has failed and damaged valves or pistons, a replacement engine with a sound chain is often the same price as the repair.
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.

Glossary
- VANOS — BMW's variable camshaft timing system. It adjusts the intake camshaft (single VANOS) or both camshafts (double VANOS) to improve torque and emissions.
- Valvetronic — BMW's variable valve lift system. It controls engine load with the intake valves instead of a throttle plate, improving economy.
- Direct injection — Fuel is injected directly into the cylinder instead of the intake port. It improves efficiency but can cause carbon build-up on the intake valves.
- Piezo injector — A fast-acting injector that uses a piezoelectric crystal. It allows precise fuel delivery but is sensitive to fuel quality.
- Wastegate — A valve that lets exhaust gas bypass the turbine to control boost pressure. Worn wastegates rattle and can cause boost faults.
- DPF — Diesel particulate filter. It traps soot and burns it off during regeneration, which needs longer journeys.
- EGR — Exhaust gas recirculation. It feeds some exhaust back into the intake to reduce NOx emissions but builds up soot.
- Swirl flaps — Flaps in the intake manifold that create swirl at low revs. On some BMW diesels they can break and enter the engine.
- Common rail — A diesel injection system with a high-pressure fuel rail feeding all injectors. It allows precise, multiple injections per cycle.
- Long block — An engine with the block, head and internals but without most ancillaries such as manifolds, turbo, alternator or starter.
- Dressed engine — An engine with most ancillaries fitted, ready to install with fewer parts transferred.
- Compression test — A measurement of the pressure each cylinder builds when cranked. Even readings show healthy rings and valves.
- Leak-down test — A test that pressurises each cylinder and measures how much air escapes, showing where any leak is.
- LCI — Life Cycle Impulse, BMW's name for a mid-life update. Engines often change at the LCI.
- xDrive — BMW's all-wheel-drive system. xDrive cars often use a different sump and oil pickup.
- DME — Digital Motor Electronics, BMW's name for the engine control unit.
- CAS, FEM and BDC — The immobiliser and body modules that must be matched to the engine control unit on modern BMWs.
- Rod bearings — The bearings between the connecting rods and the crankshaft. On several M engines they wear and are replaced preventively.
- ITB — Individual throttle bodies, one per cylinder, used on most naturally aspirated M engines for sharp response.
- Timing chain tensioner — A hydraulic or spring device that keeps the timing chain tight. Worn tensioners cause cold-start rattle.
- Rear-mounted timing chain — A timing chain at the gearbox end of the engine. Replacing it normally requires removing the engine.
- Electric water pump — A water pump driven by an electric motor. It needs a diagnostic bleeding routine when the system is refilled.
- TU — Technical Update, BMW's suffix for a revised version of an engine.
Our verdict
The BMW E90, E91, E92 and E93 3 Series offers a wide choice of engines, and the right replacement depends on your exact model, build date and gearbox. Confirm the code with your VIN, choose a unit with known history, replace the known weak parts while it is out, and the car will be back on the road for years.
