Replacing a Subaru engine typically costs about $4,000 to $8,000 in total, with higher-end setups potentially reaching $9,000 to $12,000 depending on the model, engine choice, and labor demands.
Engine replacement involves choosing between used or remanufactured engines, newer OEM or aftermarket options, and whether additional work like head gasket or timing service is needed. Price can vary by location, shop, and whether you’re tackling ancillary repairs at the same time.
Engine replacement options and price ranges
Below are the common routes owners pursue for a Subaru engine swap, listed from typically less costly to more involved options.
- Used or remanufactured engine (non-OEM). Engine cost typically $1,500–$3,000; installed total roughly $3,500–$6,500.
- Remanufactured/rebuilt engine with warranty. Engine cost typically $2,500–$4,500; installed total about $4,000–$7,500.
- New OEM long-block or reputable aftermarket engine. Engine cost typically $3,500–$6,000; installed total about $5,000–$9,000.
- Turbocharged or WRX/STI-specific considerations (may involve turbo components or high-performance builds). Engine cost typically $4,000–$7,000+; installed total often $7,000–$12,000+ depending on parts and labor.
Prices are influenced by the source of the engine, whether accessories are included, expectations around core charges, and the shop’s labor rate. Always obtain a detailed, written estimate that breaks out parts, labor, and any ancillary work.
What drives the cost
Several factors determine the final tally. A snapshot of the most impactful variables follows.
- Engine type and source (used, remanufactured, new OEM, or aftermarket long-block).
- Model, year, and engine platform (older EJ engines vs. newer FA or EZ/FV-series engines).
- Labor rates by region and shop; some shops charge more for specialized Subaru expertise.
- Required ancillary work (timing belt/chain service, water pump, head gasket replacement, seals, hoses, fluids).
- Core charges and shipping costs for the engine, especially if the unit is rebuilt or sourced from far away.
- Warranty length and coverage for the engine and for labor.
Understanding these factors helps you compare quotes and avoid surprises. Confirm what is and isn’t covered by the quoted price and whether additional services are recommended or required during installation.
Typical ranges by engine option
For shoppers aiming to budget, here are practical installed-range expectations across common options in the U.S. market in recent years.
- Used or non-OEM remanufactured engine: Engine $1,500–$3,000; installed total around $3,500–$6,500.
- Remanufactured engine with warranty: Engine $2,500–$4,500; installed total about $4,000–$7,500.
- New OEM long-block or reputable aftermarket engine: Engine $3,500–$6,000; installed total about $5,000–$9,000.
- Turbocharged/WRX-STI-specific or high-performance builds: Engine $4,000–$7,000+; installed total often $7,000–$12,000+.
Note that these ranges assume typical regional labor rates and standard installation scopes. If a shop includes additional components (ex: turbo hardware, upgraded cooling, or performance parts), the total can rise further. Always request a line-item estimate and ask about core charges, warranty terms, and what is included in the installation.
Warranty and aftercare
Warranty coverage
Remanufactured engines commonly come with a 12–36 month warranty, depending on the supplier and whether the installation is performed by a dealer or independent shop. Some shops offer longer labor warranties, but coverage varies widely—read the fine print to understand what is and isn’t covered and whether it transfers if you sell the vehicle.
What else to consider
Ask whether the quote includes related services such as timing belt/chain refresh, water pump, oil changes, coolant, and hoses. For head gasket-prone Subarus, many technicians recommend inspecting and possibly replacing the head gasket during an engine swap. If the vehicle has a turbocharger (e.g., WRX/STI), confirm whether the turbo is upgraded or replaced and whether that adds to the cost or warranty terms.
Tips to save money and avoid surprises
Smart preparation can keep costs predictable. Consider these practices when planning a Subaru engine replacement.
- Get multiple, detailed quotes from reputable shops that specialize in Subarus.
- Ask for a long-block-only option versus a fully accessorized engine package, and clarify what is included in labor.
- Inquire about core charges, shipping, and any additional repairs that may be required now or later.
- Check warranty length and transferability for both engine and labor.
- Factor in potential ancillary repairs (head gasket, timing components, cooling system) that are commonly recommended during a swap.
By comparing apples-to-apples quotes and choosing a trusted shop, you can minimize the risk of hidden costs and ensure a durable, properly installed replacement engine.
Summary
For most Subaru owners, replacing an engine will cost in the broad range of $4,000 to $8,000 installed, with variations based on engine type, source, and local labor rates. Options include used/remanufactured engines, remanufactured units with warranties, and new OEM or aftermarket long-blocks, with turbocharged models or high-performance builds typically at the higher end. Always obtain a detailed estimate that items parts, labor, cores, and any necessary ancillary services, and seek warranty information before proceeding.
