Buying a used Porsche engine
Porsche engine buying is decided almost entirely by engine family. One family carries a documented risk that changes the value of every car it went into.
M96 / M97 flat-sixroughly 1997-2005
The intermediate shaft bearing concern affects the 996 generation 911, the 986 Boxster and the 987. The smaller single-row bearing used in many 2000 to 2005 cars draws the most concern. Documented outcomes range from very early failure to none at all across high mileage, so it is a risk factor rather than a schedule.
9A1 direct injection flat-six
Porsche moved away from the intermediate shaft design in this later family, which is why the IMS concern does not carry across the whole brand.
Before you order
Identify the engine family, not the model year. Porsche changed specifications mid-generation, and whether a retrofit bearing was already fitted is worth asking about while the engine is out.

VIN & interchange codes
How Porsche engines are identified by VIN
Porsche engines of the same displacement can differ by VIN code, emissions package, and build - which changes the correct part. Here is the real interchange breakdown for a 2015 Porsche 911/930, the kind of detail a specialist confirms from your VIN before anything ships:
| Engine / application | Interchange # |
|---|---|
| (991 model) (96-1/2" WB) 3.4L (VIN A, 5th digit) | 300-88981 |
| (991 model) (96-1/2" WB) 3.8L VIN B (5th digit) | 300-88039 |
| (991 model) (96-1/2" WB) 3.8L VIN C (5th digit) | 300-88040 |
| (991 model) (96-1/2" WB) 3.8L VIN D (5th digit) | 300-88041 |
Interchange data shown for reference. Availability and exact application are confirmed per order from your complete VIN.

FAQ
Used Porsche engines & transmissions
How much does a used Porsche engine cost?
Price tracks the engine family more than the model year, and on Porsche that usually means which of the M96 / M97 flat-six and 9A1 direct injection flat-six you need. Displacement alone does not settle it, because the same badge can cover variants that differ in cost and availability. Tell us the year, model and VIN and you get a firm quote on the engine your vehicle actually takes, with availability confirmed before you pay.
Which Porsche engines do you carry?
We regularly source Porsche engines across the lineup, including the 4.8L V8, 4.0L H6, 3.8L H6, 3.8L H6 Twin-Turbo, 3.6L H6 Turbo, 3.6L H6. If you don't see your exact engine, tell us the year, model, and VIN and a specialist confirms the right one before you pay.
Do you sell used Porsche transmissions too?
Yes. Alongside used and remanufactured Porsche engines, we source manual, automatic, and CVT Porsche transmissions matched to your vehicle, backed by the same 12-month parts-replacement warranty.
Will the engine fit my exact Porsche?
Fitment is confirmed before you pay. Identify the engine family, not the model year. Porsche changed specifications mid-generation, and whether a retrofit bearing was already fitted is worth asking about while the engine is out. Give us the year, model and 17-digit VIN and a specialist matches the correct engine to your exact application.
Are your used engines and transmissions tested?
Yes. Every used engine and transmission is compression- and oil-pressure tested and put through a rigorous inspection process by automotive experts before they ship.
What warranty comes with a part?
Every engine and transmission includes a 12-month parts-replacement warranty, plus lifetime support from ASE-certified experts. Approved claims are handled by replacement or store credit - we do not issue cash refunds. Labor is not covered on the standard warranty. You can upgrade to 3-year parts and labor coverage for $499 at the time of purchase. Full warranty details are provided with your order.
Can I get a longer warranty that covers labor?
Yes. The standard coverage is 12 months on parts. For $499 you can upgrade to a 3-year warranty that covers both parts and labor, purchased at the time of your order. Ask your specialist to add it when you confirm your part.
