S55B30T0 compared with other S55 versions
| Code | Capacity | Power | Torque | Years |
|---|---|---|---|---|
| S55B30 | 3.0 L | 431 hp | 550 Nm | 2014–2020 |
| S55B30T0 | 3.0 L | 370 hp | 465 Nm | 2015–2018 |
S55B30T0 or S55B30?
The S55B30 has 61 hp more than the S55B30T0 (431 against 370 hp), from the same 3.0 L, and was built 2014–2020. Versions of the same size share the block and most mounting points, but the turbo or intake, injectors, software and sometimes the sump differ. Fitting one in place of the other usually means transferring parts and coding the engine control unit, so the simplest choice is the code your car left the factory with.
Common S55B30T0 problems
The S55B30T0 shares its weak points with the rest of the S55 family. These are the faults to check on a used unit and on your own engine. The full explanation of each is in the S55 guide.
| Known fault | What to check |
|---|---|
| Crank hub | Ask whether the crank hub has been upgraded. |
| Charge pipe | Check for boost leaks. |
| Oil leaks | Look for oil around the head. |
| Cooling | Check for coolant loss. |
Crank hub. The crank hub on heavily tuned engines can slip. Many owners fit a pinned or keyed crank hub when tuning.
S55B30T0 maintenance
- 0W-30 or 5W-30 BMW Longlife-01, about 6.5 litres.
- Oil every 10,000 km or yearly; shorter for track use.
- Timing chain at the front.
Will the S55B30T0 fit my car?
Will the S55B30T0 fit my BMW F87 M2?
The S55B30T0 is the original engine for the BMW F87 M2, which makes it the straightforward choice. The M2 was built 2016–2021, and the S55B30T0 was produced 2015–2018, 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.

Buying a used S55B30T0: checklist
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Questions about the S55B30T0
Which years were BMW S55 engines made?
BMW built the S55 engines we list from about 2014 to 2020. The S55B30 ran from 2014 to 2020.
They went into chassis F80, F82, F83 and F87. The exact year of a car matters, because BMW sometimes changed the engine version or its parts in the middle of a model's life.
Each listing in our yard names the engine year, so you can match it to the build date of your car.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.
What should I check on a used BMW S55 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 S55 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.
You can ask for extra photos, a close-up of the code stamp or a short video before you order. 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 should I know about the BMW S55 engine?
BMW S55 3.0 twin-turbo engines for the F80 M3, F82 M4 and M2 Competition. We list one version: S55B30 (3.0 liter (2,979 cc), 317 kW (431 HP), 2014 to 2020).
Because there is only one version, the code is easy to match. You still need the engine computer and wiring that suit your car.
The S55 family was used in chassis F80, F82, F83 and F87. The photos on each listing show the actual engine, not a stock picture. The yard checks the code, records what is bolted on, and seals the openings before the engine is offered.
Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.
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.

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.
