Buying a used Subaru engine
Subaru is the make where engine family and model year matter most, because the boxer engines carry two distinct and well-documented issues across different generations.
EJ25 2.5L (naturally aspirated)
The head gasket history is the defining Subaru issue, concentrated in the late 1990s through the mid 2000s, with a related service action extending to some 2008 vehicles. Overheating is what converts a marginal gasket into a failed one, so donor cooling history matters.
FB20 / FB25roughly 2012-2018
Oil consumption is the widely reported concern on this generation, affecting Impreza, Crosstrek, Forester, Legacy and Outback across specific years. Check documented consumption on any donor rather than assuming the newer engine is the safer one.
EJ257 2.5L Turbo
Ringland failure is the reported risk on tuned or hard-used turbo engines. Provenance matters more here than on any other engine we sell: an untuned, documented donor is worth a premium.
Before you order
Confirm which engine family you actually have before ordering. Subaru used the 2.5L displacement across the EJ and FB families, and they share almost nothing that matters for fitment.

VIN & interchange codes
How Subaru engines are identified by VIN
Subaru 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 Subaru Legacy, the kind of detail a specialist confirms from your VIN before anything ships:
| Engine / application | Interchange # |
|---|---|
| 2.5L VIN A (6th digit) MT (Canada market) | 300-91083 |
| 2.5L VIN A (6th digit) AT (CVT, PZEV) | 300-91084 |
| 2.5L VIN B (6th digit, AT) | 300-91085 |
| 2.5L VIN C (6th digit) AT | 300-91085 |
| 2.5L VIN C (6th digit) MT (Canada market) | 300-91083 |
| 2.5L VIN D (6th digit) MT (Canada market) | 300-91083 |
| 2.5L VIN D (6th digit) AT (CVT, PZEV) | 300-91084 |
| 3.6L VIN E (6th digit, DOHC) | 300-91086 |

FAQ
Used Subaru engines & transmissions
How much does a used Subaru engine cost?
Price tracks the engine family more than the model year, and on Subaru that usually means which of the EJ25 2.5L (naturally aspirated), FB20 / FB25 and EJ257 2.5L 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 Subaru engines do you carry?
We regularly source Subaru engines across the lineup, including the 3.6L H6, 3.0L H6, 2.5L H4, 2.5L H4 Turbo, 2.2L H4, 2.0L H4. 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 Subaru transmissions too?
Yes. Alongside used and remanufactured Subaru engines, we source manual, automatic, and CVT Subaru transmissions matched to your vehicle, backed by the same 12-month parts-replacement warranty.
Will the engine fit my exact Subaru?
Fitment is confirmed before you pay. Confirm which engine family you actually have before ordering. Subaru used the 2.5L displacement across the EJ and FB families, and they share almost nothing that matters for fitment. 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.
