Used Subaru Forester FB25 2.5L Engine for Sale (2011–2016) – JDM Import

This listing covers a used FB25 2.5L engine pulled from a Japanese-market Subaru Forester, imported as-is and sold as a replacement unit for 2011–2016 Forester models. It has not been rebuilt, remanufactured, or internally modified in any way. What you’re getting is a used engine in its original factory configuration.

Engine Condition and Source

This is a used engine, sourced directly from Japan. JDM vehicles go through strict government inspection cycles and are typically retired from service earlier than vehicles in other markets, which is part of why used JDM engines are a common choice for replacement work. That said, mileage is not guaranteed and should be treated as unknown unless specifically stated otherwise.

Before the engine ships, we drain the fluids, clean the exterior, do a visual inspection, and run a compression test to confirm basic mechanical function. This is a condition check, not a rebuild process.

Fitment

This engine is intended for Subaru Forester models originally equipped with the naturally aspirated FB25 from the factory. Compatible years are 2011 through 2016. Subaru engines can vary in emissions configuration, ECU calibration, and regional specification, so fitment needs to be confirmed by the buyer or their installer before purchasing. That part is on you.

What’s Included

The engine ships as a complete assembly with the major accessories still mounted, as shown in the product photos. Included components are:

• FB25 long block assembly
• Intake and exhaust manifolds
• Throttle body
• Ignition coil packs
• Fuel injectors and fuel rail
• Sensors mounted to the engine
• Alternator
• Air conditioning compressor
• Starter motor
• Power steering pump (if present on the donor vehicle)

Minor brackets, sensors, or small components may vary depending on the donor vehicle and production year.

Specifications

Intended Use

This engine is for standard replacement in a compatible Forester. Common reasons people buy it include worn or high-mileage engines, internal failure, oil consumption issues, or overheating damage. It is not intended for performance builds, forced induction, or anything outside factory specifications without further modification work.

Installation

Professional installation is strongly recommended. Subaru boxer engines have specific requirements around timing, torque sequencing, and component alignment that make them less forgiving of shortcuts. During the swap, wear items like gaskets, seals, and belts should be replaced, ECU compatibility should be verified, and the engine should be properly primed before startup. Installation errors are not covered by the seller.

Emissions

This is a Japanese-market engine. Emissions equipment may differ from U.S.-spec configurations. The buyer is responsible for confirming compliance with their state or local regulations before purchasing.

Shipping

The engine ships freight within the continental United States on a secured pallet, with liftgate delivery and a delivery appointment included. A tracking number is provided once the shipment goes out. A commercial delivery address is preferred — residential delivery can be arranged but may require additional coordination.

A Few Things to Keep in Mind

This is a used engine. Mileage is not guaranteed. Cosmetic wear is normal and should be expected. Accessories are included as-is. No claims are made beyond what’s stated in this listing. Purchasing this engine means you’ve read and accepted these conditions.
