The Achilles' Heel of the Competition & CS
BMW M2 Competition, M2 CS (F87, 2018-2021, S55B30A & S55B30T0)
20,000 - 60,000 miles (can occur on stock or tuned engines)
The crank hub is attached to the crankshaft via friction alone, not a keyway. Sudden load changes - aggressive downshifts or high-rpm launches - can cause the hub to spin on the crank, jumping timing and allowing valves to contact pistons.
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Minor - Preventative Crank Hub Fix - Capture hub + bolt upgrade Minor | £2,500 - £3,500 | £1,800 - £2,500 | Fit aftermarket pinned or captured hub design without removing engine | Permanent prevention if done proactively. Best for tuned or track-used cars |
Intermediate - Timing Correction & Hub Replacement - Post-spin (no piston contact) Intermediate | £5,000 - £7,000 | £3,500 - £5,000 | Remove oil pan, timing components, replace hub, re-time engine | Successful only if spin detected immediately and no valve contact occurred |
Full Replacement - Rebuilt S55 Engine - With upgraded hub Best Value | £12,000 - £16,000 | £7,500 - £12,000 | Supply & fit fully rebuilt S55 with captured/pinned hub, bench tested, 12-month warranty | Permanent solution. Required if valves bent or cylinder damage present |
If your M2 Competition or CS is still running fine, proactively fitting a crank hub capture kit is excellent value at around £2,000 from a specialist. If the hub has already spun, have a borescope inspection performed immediately. If valves hit pistons, skip the intermediate repair - a rebuilt engine with an upgraded hub is the only reliable long-term fix. On an M2 worth £25,000-£45,000, £7,500-£10,000 for a properly rebuilt S55 makes financial sense.
From crank hub failures on S55-powered Competition and CS models to charge pipe issues on early N55 cars, M2 engine problems are predictable and manageable - if you know the costs and act early. EngineMarket connects you with trusted UK BMW M2 specialists who supply rebuilt engines with upgraded components designed to eliminate the original failure points. Whether you need a preventative crank hub fix, a turbo rebuild, or a complete S55 or N55 replacement with warranty, compare prices from our network and get back on the road without the main dealer premium.

The BMW M2 has always been powered exclusively by a 3.0-litre turbocharged inline-six petrol engine, spanning the N55, S55 and S58 families. The original F87-generation M2 (2016-2018) used the N55B30T0, while the M2 Competition (2018-2021) and M2 CS (2020-2021) received the high-output S55 derived from the M3/M4. The current G87-generation M2 (2023-present) is powered by the S58, which features a closed-deck block and resolves the crank hub vulnerability of its predecessor.

FAQ
Question 1
A BMW M2 replacement engine typically costs £3,200-£10,500 supply-only, depending on engine code (N55, S55 or S58) and condition type.
Key points
Question 2
Yes - the S55 crank hub spin is the most documented failure on M2 Competition and CS models, affecting both stock and tuned cars between 20,000-60,000 miles .
Key points
Question 3
On the 2016-2018 N55-powered M2, the most common failures are cracked charge pipes (sudden boost loss and limp mode), ignition coil misfires, and oil leaks from ageing gaskets .
Key points
Question 4
The S58 in the G87 M2 is mechanically the most robust, having resolved the S55's crank hub vulnerability. The N55 is reliable with one cheap preventative fix, while the S55 needs a crank hub upgrade for peace of mind .
Key points
Question 5
Yes - all three M2 engines respond well to tuning, but the S55 requires a crank hub fix before adding power. The S58 offers substantial gains with proper supporting mods .
Key points
Question 6
A well-maintained BMW M2 engine typically lasts 100,000-150,000 miles. The N55 and S55 need preventative fixes around 50,000-80,000 miles to reach higher mileage reliably .
Key points
Question 7
On an F87 M2 worth £18,000-£45,000, spending £4,000-£9,000 on a rebuilt engine with upgraded components is financially sensible compared to selling with a failed engine.
Key points
Question 8
Ageing gaskets - particularly the valve cover, oil filter housing and oil pan - are the primary cause of oil leaks on the F87 M2, typically appearing from 50,000 miles onward .
Key points
Question 9
Rebuilt engines are fully disassembled and machined with new parts - the premium choice. Reconditioned means inspected and worn parts replaced to factory spec. Used engines are tested donor units with existing mileage .
Key points
Question 10
For routine maintenance either works, but for engine replacement or S55 crank hub work, a BMW specialist offers better value - typically 30-50% lower labour rates and proven experience with M engines .
