Finding the right Porsche engine
Porsche’s sports cars have run through four water-cooled flat-six families since 1997 — the M96 (1997–2004), the M97 (2005–2008), the direct-injection MA1 (2009–2016) and the turbocharged 9A2 (2017 on) — alongside the separate Mezger engines of the Turbo, GT2 and GT3. The Cayenne, Panamera and Macan use Volkswagen Group-based V6s and V8s instead, so a Porsche engine can be anything from a 2.0L turbo four to a 4.8L twin-turbo V8.
The families matter because the faults follow them. The intermediate-shaft bearing belongs to the M96 and M97 only, bore scoring is concentrated in the Lokasil-block engines, and nothing from 2009 on has an intermediate shaft at all. Give us your VIN and we’ll match the exact one.
Engine Families
The engines behind most Porsche vehicles
M96 and M97 flat-six (1997–2008)
The M96: 2.5L in the 1997–1999 Boxster, 2.7L and 3.2L in the 2000–2004 Boxster and Boxster S, 3.4L in the 1999–2001 911 Carrera (996) and 3.6L in the 2002–2004 996. The M97: 2.7L, 3.2L and 3.4L in the 2005–2008 Boxster (987) and 2006–2008 Cayman S, 3.6L and 3.8L in the 2005–2008 911 Carrera and Carrera S (997.1). Both carry the intermediate-shaft bearing; the M96 also leaks at the rear main seal and some early 2.5L and 3.4L engines slipped or cracked a cylinder liner, while the 997.1’s Lokasil cylinders are the most prone to bore scoring.
MA1 (9A1) flat-six (2009–2016)
Direct injection and no intermediate shaft. 2.9L and 3.4L in the 2009–2012 Boxster and Cayman (987.2), 2.7L, 3.4L and 3.8L in the 2013–2016 981, 3.6L and 3.8L in the 2009–2012 911 (997.2), 3.4L and 3.8L in the 2012–2016 911 (991.1), and the 4.0L in the 991 GT3 RS and 911 R. Bore scoring is far less common on the 997.2 than on the 997.1.
9A2 turbo flat-six and flat-four (2017 on)
The 3.0L twin-turbo in the 2017–2019 911 (991.2) and 2020–2024 992, the 2.0L and 2.5L turbo flat-fours in the 2017–2025 718 Boxster and Cayman, the 3.7L and 3.8L twin-turbos in the Turbo and Turbo S, and the 3.6L T-Hybrid in the 2025 992.2. The non-turbo 4.0L flat-six sits in the 718 GTS 4.0, GT4, Spyder and GT4 RS (2020 on) and the 992 GT3.
Mezger engines — Turbo, GT2 and GT3
The 996 and 997 Turbo, GT2 and GT3 have the separate Mezger engine, which is not affected by the intermediate-shaft bearing. One GT engine does have a campaign: every 2014 911 GT3 (991) had its engine replaced under recall 14V090000, after a connecting rod could come loose and damage the crankcase.
Cayenne and Panamera V6 and V8
Volkswagen Group-based engines. Cayenne 9PA (2003–2010): 3.2L and 3.6L VR6, 4.5L V8 and twin-turbo (2003–2006), 4.8L V8 and twin-turbo (2008–2010). Cayenne 92A (2011–2018) and Panamera 970 (2010–2016): 3.6L V6, 4.8L V8 and twin-turbo, 3.0L supercharged hybrid V6, 3.0L and 3.6L twin-turbo V6, 3.0L V6 diesel. Panamera 971 (2017–2024) and Cayenne 9YA (2019 on): 3.0L turbo V6, 2.9L and 4.0L twin-turbos and hybrids. The 4.5L V8 has a Lokasil block and its own bore-scoring history, the 9PA’s plastic coolant pipes crack and overheat the engine (later cars have metal pipes), and two recalls are worth checking: 17V368000 (2011 Panamera 4.8L, camshaft adjuster screws) and 12V329000 (2011–2012 Cayenne Turbo and Panamera Turbo, turbocharger turbine wheels).
Macan V6 and 2.0L four
The Macan (95B, 2015 on) has a 3.0L twin-turbo V6 in the 2015–2018 S and GTS, a 3.6L twin-turbo in the 2015–2018 Turbo, the 2.0L EA888 turbo four from 2017, a 3.0L single-turbo V6 in the 2019–2021 S and the 2.9L twin-turbo in the GTS and Turbo from 2020 and the S from 2022.

FAQ
Used Porsche engine questions, answered
How do I find out which engine my Porsche has?
The fifth character of the VIN is an engine letter, but it is model-specific, so it only decodes together with the type code in positions 7–8 (99 for the 911, 98 for the Boxster and Cayman, 9P for the 2003–2009 Cayenne, A7 for the Panamera, A5 for the Macan) and the model year in position 10. The engine type (M96, M97, MA1) and engine number are on the vehicle data sticker and stamped on the crankcase. Send us the full VIN and we will confirm the exact version. On our quote form the 911 is listed as “911930” and the Cayman as “Cayman S”.
What is the difference between a used, remanufactured and rebuilt engine?
A used engine is a tested unit taken from a donor vehicle. A rebuilt engine has been disassembled, repaired and reassembled. A remanufactured engine has been restored to like-new condition. Tell us your vehicle and budget and we will recommend the right option.
Does my Boxster or 911 have the IMS bearing problem?
Only if it has an M96 or M97 engine: a 1997–2008 Boxster, a 2006–2008 Cayman or a 1999–2008 911 Carrera. The 1997–1999 cars (some 2000) have a dual-row bearing that rarely fails; the 2000/2001–2005 cars have the single-row bearing that fails most often; and the 2006–2008 cars (some late 2005) have a larger bearing that is not serviceable but seldom gives trouble. The bearing type cannot be read from the VIN or the engine number — only a visual inspection tells. The Turbo, GT2 and GT3 and everything from 2009 on are not affected. A class action, Eisen v. Porsche Cars North America, covered Boxsters built between May 2001 and February 2005; its settlement was agreed in 2013 and its claims period is widely reported to have closed.
Does a used Porsche engine come with a warranty?
Yes. Every engine we sell is covered by warranty, and extended cover is available at extra cost. The full terms are in our Warranty Policy.
