Used BMW M3 Crankshaft

The BMW M3 has used significantly different engines across its generations — the E30 M3 (1986–1991) used the S14 four-cylinder, the E36 M3 (1992–1999) the S50/S52, the E46 M3 (2000–2006) the S54, the E90/E92/E93 M3 (2007–2013) the S65 V8, the F80 M3 (2014–2018) the S55 turbocharged inline-six, and the G80 M3 (2021–present) the S58 turbocharged inline-six. Each of these engines is entirely different in design, displacement, and architecture, so crankshafts do not cross between generations. Give the breaker your exact engine code — found on your V5 or via a VIN check — to make sure you're quoted the right part.

Yes, every variant of the BMW M3 across all generations has been powered by a petrol internal combustion engine, so every M3 has a crankshaft — this is a core rotating assembly component present in all of them. Unlike some parts that only appear on certain drivetrain layouts or forced-induction variants, a crankshaft is not optional equipment. What varies is the crankshaft's specification, stroke, material, and counterbalancing, which differ substantially between the S14, S50, S52, S54, S65, S55, and S58 engines used across M3 generations.

Both the pre-facelift and post-facelift E92 M3 used the same S65 4.0-litre V8 engine throughout the generation (2007–2013), so in principle the crankshaft specification did not change at the 2010 facelift. However, whether there were any ancillary or tolerance changes to internal components mid-production is something you should confirm with the breaker against your exact registration and engine code, as mid-run revisions are not always publicly documented. Always supply your engine code rather than just the year to get the most accurate match.

No — body style makes no difference whatsoever to crankshaft fitment. Both body styles of the E46 M3 (2000–2006) used the same S54 3.2-litre inline-six engine, and the crankshaft is an internal engine component entirely unaffected by what sits above or around it. Focus on matching the engine code, which is the detail that actually matters when speaking to a breaker.

The standard F80 M3 (2014–2018) and the M3 Competition both used the S55 turbocharged 3.0-litre inline-six engine, and trim level or Competition Pack designation does not affect the crankshaft specification — the Competition package primarily brought suspension, exhaust, and software changes rather than internal engine differences. That said, always quote your exact engine code to the breaker to confirm, as small internal specification differences between build dates are possible and the breaker will want to check against your registration. Trim level alone is not a reliable matching criterion for a mechanical component like this.

The G80 M3 (2021–present) in both rear-wheel-drive and xDrive four-wheel-drive form uses the same S58 turbocharged 3.0-litre inline-six engine, so the drivetrain layout does not alter the crankshaft itself. In principle the crankshaft should be the same component, but whether there are any internal tolerance or build-spec differences between xDrive and RWD variants is worth confirming with the breaker against your specific engine code and registration before committing to a purchase.
