Porsche Engines We Cover

Real Porsche engines from our warehouse, tested and ready to ship. Pick the family, then the year page shows exactly which models and variants are in stock.

Cayenne 4.8L V8 (S and GTS)

Cayenne S and GTS (2008–2018). Our deepest Porsche line — the naturally aspirated M48 4.8, listed as w/o turbo with its VIN code because the S and the Turbo of the same year share a block and not the heads, pistons, intake or controller.

Cayenne and Panamera 4.8L V8 Turbo

Cayenne Turbo and Turbo S (2008–2018), Panamera Turbo, GTS and 4S (2010–2016). The twin-turbo 4.8 and the Panamera V8s — listed by VIN code and by RWD or AWD on the Panamera, because the Panamera S rear-drive unit and the 4S all-wheel-drive unit carry different sumps and mounts.

Cayenne and Panamera 3.6L V6 (VR6 and EA837)

Cayenne (2008–2018), Panamera and Panamera 4 (2011–2016). The narrow-angle VR6 of the 2008–2010 Cayenne and the direct-injected 3.6 that replaced it — listed by VIN code and by RWD or AWD, because the two 3.6s do not swap and the AWD unit carries its own pan and mounts.

First-Generation Cayenne 4.5L V8 and 3.2L VR6

Cayenne S and Turbo 4.5 (2003–2006), Cayenne 3.2 (2004–2006). The original 955 Cayenne engines — the 4.5 V8 in naturally aspirated and twin-turbo builds, listed as turbo or w/o turbo with its VIN code, and the VW-sourced 3.2 VR6 of the base model.

3.0L and 2.9L Twin-Turbo V6, 4.0L V8 and E-Hybrid (2017–2019)

Panamera, Panamera 4 and 4S (2017–2019), Cayenne (2019), Panamera and Cayenne E-Hybrid. The current EA839 3.0 and 2.9 twin-turbo V6s, the 4.0 twin-turbo V8, and the hybrid builds (VIN E, VIN H) — listed by VIN code because the hybrid units carry the motor flange and their own controller.

Boxster and Cayman M96 / M97 Flat-Six (1997–2012)

Boxster and Boxster S (1997–2012), Cayman and Cayman S (2006–2012). The water-cooled flat-six in 2.5, 2.7, 3.2 and 3.4 — listed by VIN code because the 986 and 987 units, and the base and S units of the same year, carry different displacements, intakes and controllers.

911 996 / 997 3.4L, 3.6L and 3.8L Flat-Six

911 Carrera, Carrera S, Targa and Turbo (1999–2012). Listed by 996 or 997 model, by VIN code, by Carrera or Targa, by electric throttle control on the early 996, and by horsepower where Porsche split the engine — the 320 hp Carrera 3.6 (VIN A) and the 415 hp Turbo 3.6 (VIN B) share a year and nothing else.

981 and 718 Boxster and Cayman (2013–2019)

Boxster and Cayman 2.7 and 3.4 (2013–2016), 718 Boxster and Cayman 2.0 and 2.5 turbo (2017–2019). The 9A1 flat-six of the 981 and the MA2 turbo flat-four of the 718 — listed by VIN code because the S and base units of the same year carry different displacements and, on the 718, different turbos.

Macan 2.0L Turbo, 3.0L and 3.6L Twin-Turbo V6

Macan (2015–2019), Macan S, GTS and Turbo. The Audi-sourced 2.0 turbo four (VIN A) and the 3.0 and 3.6 twin-turbo V6s (VIN B and Turbo) — listed by VIN code because the four and the V6s share nothing, and the S and Turbo V6s carry different turbos and calibration.

Why Buy a Used Porsche Engine from Auto Power Source

Porsche has run engines that share a displacement and nothing else — a 4.8 Cayenne is a naturally aspirated S engine or a twin-turbo Turbo engine, a 3.6 is a VR6 or a direct-injected V6 depending on the year, a 3.4 is a 996 Carrera engine, a Cayman S engine or a 981 Boxster S engine, and a 911 3.6 is a 320 hp Carrera or a 415 hp Turbo. Every product on this page is titled by VIN code (the 5th digit on Porsche), by turbo or w/o turbo, by RWD or AWD on the Panamera and Cayenne, by 996 or 997 model, and by horsepower and body style where Porsche split the engine. Our 238 verified Porsche engines cover the whole run: the 4.8 V8s in the Cayenne and Panamera, the 3.6 V6s in the Cayenne and Panamera, the first-generation Cayenne 4.5 and 3.2, the current twin-turbo V6s and hybrids, the M96 and M97 flat-sixes in the Boxster, Cayman and 911, the 981 and 718 engines, and the Macan four and V6s.

Every Porsche engine we sell has been pulled from a low-mileage donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Each unit goes through our six-step inspection — VIN-matching against the donor and against your vehicle, compression and leak-down testing of every cylinder, noise verification, full visual inspection of block, heads and timing cover, multi-angle photography for your approval, and palletized freight. M96 and M97 units get an intermediate-shaft bearing and bore-scoring check, turbo units get a turbo-shaft and PCV inspection, and V8 units get a timing-chain and cam-adjuster review. Rejected units never reach the buyer.

You pay a fraction of dealer-new pricing for the same Porsche engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason — no restocking fees. The warranty printed on the listing — with extended coverage up to 3 years available — covers you if anything goes wrong after install. Across 100K+ engines and transmissions in stock, we hold a 0% fitment-related return rate.
