Engine swap questions for the BMW F22 and F23 2 Series and F87 M2

Owners often ask whether a more powerful engine from another BMW F22 and F23 2 Series and F87 M2 model can be fitted. These answers show what each upgrade involves.

Can I fit the S55B30 from the F87 M2 Competition into an F22 M235i?

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 S55B30 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 105 hp and 100 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.

Can I fit the S55B30T0 from the F22 M2 into an F22 M235i?

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 S55B30T0 needs its own wiring harness and ECU, the matching gearbox or clutch, and often a different sump, cooling and exhaust. The gain is 44 hp and 15 Nm. In Germany and most of Europe a swap must be inspected and registered; check with your testing station first.

Can I fit the S55B30T0 from the F22 M2 into an F22 228i?

It is a conversion rather than a replacement. The S55B30T0 is an inline-6 and the N20B20 an inline-4, so mounts, sump, cooling, exhaust, wiring and ECU all change. The gain is 125 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 F22 and F23 2 Series and F87 M2

• The M2 moved from the N55 to the S55 in the Competition.

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.

N55: Remaps add a lot; upgraded turbos and fuel pumps take it further.

N20 and N26: Remaps unlock significant gains. A healthy N20 with updated guides is a good tuning base.

S55: Remaps and bolt-ons reach well over 500 hp; check the crank hub first.

How to identify the right engine for your BMW F22 and F23 2 Series and F87 M2

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 F22 and F23 2 Series and F87 M2 engine prices

Across 56 BMW F22 and F23 2 Series and F87 M2 engine units in our stock today, prices start at 1.296,00 € and reach 11.894,00 €. The median — the price in the middle of the range — is 9.621,00 €.

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 F22 and F23 2 Series and F87 M2 engine prices by model year

Engines from 2010–2014 have a median of 8.648,00 €, while units from 2020–2024 sit at 10.313,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

Buying checklist for a BMW F22 and F23 2 Series and F87 M2 engine

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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 F22 and F23 2 Series and F87 M2

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. Reset VANOS adaptations. Clear the VANOS adaptations so the ECU learns the camshaft positions of the new engine.
13. Teach the Valvetronic limit stops. Run the Valvetronic learning routine so the ECU knows the eccentric shaft limits.
14. 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.
15. 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 F22 and F23 2 Series and F87 M2

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.

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.

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 F22 and F23 2 Series and F87 M2?

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.

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.

Questions about the engines in the BMW F22 and F23 2 Series and F87 M2

What is the BMW S55B30 engine?

The BMW S55B30 is a 3.0 liter (2,979 cc) petrol engine from the S55 family. It has an inline 6, DOHC, 24 valve layout with twin turbochargers, and makes 317 kW (431 HP) with 550 Nm of torque. BMW built it from 2014 to 2020 and it meets the Euro 6 emission standard.

You find the S55B30 in the BMW F80 M3, BMW F82 M4, BMW F83 M4 and BMW F87 M2 Competition. What we list: BMW S55 3.0 twin-turbo engines for the F80 M3, F82 M4 and M2 Competition.

At Autowerke Engines every S55B30 is a real used engine from our yard in Hamburg. Each engine in the yard is inspected in Hamburg. The code is matched to the listing, the parts on the engine are recorded, the openings are sealed and the real unit is photographed. Each listing shows the year, the mileage and the price, so you can compare units side by side.

What should I replace when I fit a used S55B30 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 S55B30?

In our yard the S55B30 is the only listed version of the S55 family. It makes 317 kW (431 HP) and 550 Nm, and was built from 2014 to 2020.

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 S55B30 a diesel or petrol engine?

The S55B30 is a petrol engine. It is a 3.0 liter (2,979 cc) inline 6, DOHC, 24 valve unit with twin turbochargers, and it was built to the Euro 6 emission standard.

The emission standard matters for registration and for low-emission zones in many cities. When you replace an engine with the same code, the car keeps the same paperwork and the same emission class.

Petrol versions need the correct catalytic converters and oxygen sensors on the car to stay legal and to keep the engine computer happy. Reuse the parts from your car if they are in good condition.

If you are not sure which version you need, send us your VIN. We tell you the right code for free.

What should I check on a used BMW N55 engine?

Start with the basics: the engine code on the block, the recorded mileage and the photos. Make sure the code matches your car and the parts you need are on the unit.

On an N55 petrol engine, a fitter usually checks the spark plugs, the coils, the timing side and the oil seals. These parts are easy to check before fitting and easy to change if needed.

Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide. An inspection certificate can travel with the order on request.

Once fitted, change the oil and filter early and drive gently at first. Report any problem right away so the warranty stays valid.

What comes with a used N20B20 engine?

Each N20B20 is sold as described on its own listing. The yard writes down the parts that are fitted to that unit, such as the turbo, the injectors, the manifolds or the alternator, so you know what arrives.

Some units are long engines with few ancillaries, others are more complete. If you need a part that is not listed, ask the desk. We often have the matching items in the yard.

Every engine is drained, sealed at each opening, strapped to a heat-treated pallet and shrink-wrapped, then photographed before it leaves the yard.

On delivery, the carrier brings the pallet to the kerb or a loading bay. Please have a forklift, a pallet truck or an engine crane ready.

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.
• Wastegate — A valve that lets exhaust gas bypass the turbine to control boost pressure. Worn wastegates rattle and can cause boost faults.
• 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.
