Buying a used Mazda engine
Mazda requests are mostly Skyactiv four-cylinders, a family with a good reliability record. The older DISI turbo is the one with a specific reputation.
2.5L Skyactiv-G
Well regarded overall, with misfires and occasional oil consumption as the recurring complaints rather than a dominant structural failure. Some 2018-2019 vehicles with this engine were recalled over the cylinder deactivation system, which is worth checking by VIN.
2.5L Skyactiv-G Turbo
Fuel dilution of the engine oil in cold-weather, short-trip driving is the widely reported concern, addressed on some vehicles by a software reprogram. It is a use-pattern issue as much as a design one, so how the donor was driven matters.
2.3L DISI Turbo
Turbocharger failure is the defining reported issue on this older family, usually traced to oil supply and skipped service intervals. Donor maintenance records matter more than mileage here.
Before you order
Skyactiv shares the 2.5L displacement across naturally aspirated and turbocharged engines that are not interchangeable. The VIN separates them, and it also tells us whether your vehicle falls in a recalled range.

VIN & interchange codes
How Mazda engines are identified by VIN
Mazda 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 Mazda CX9, the kind of detail a specialist confirms from your VIN before anything ships:
| Engine / application | Interchange # |
|---|---|
| (3.7L) VIN A (8th digit) | 300-66137D |
| (3.7L) VIN V (8th digit) | 300-66137D |
Interchange data shown for reference. Availability and exact application are confirmed per order from your complete VIN.

FAQ
Used Mazda engines & transmissions
How much does a used Mazda engine cost?
Price tracks the engine family more than the model year, and on Mazda that usually means which of the 2.5L Skyactiv-G, 2.5L Skyactiv-G Turbo and 2.3L DISI Turbo 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 Mazda engines do you carry?
We regularly source Mazda engines across the lineup, including the 4.0L V6, 3.0L V6, 2.5L I4, 2.5L V6, 2.3L I4, 2.3L I4 Turbo. 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 Mazda transmissions too?
Yes. Alongside used and remanufactured Mazda engines, we source manual, automatic, and CVT Mazda transmissions matched to your vehicle, backed by the same 12-month parts-replacement warranty.
Will the engine fit my exact Mazda?
Fitment is confirmed before you pay. Skyactiv shares the 2.5L displacement across naturally aspirated and turbocharged engines that are not interchangeable. The VIN separates them, and it also tells us whether your vehicle falls in a recalled range. 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.
