2013-2018 Subaru Outback JDM Engine DOHC H4 2.5L FB25 — Complete Swap (64K Miles)

Low-mileage FB25 pulled from a 2013-2018 JDM Outback donor, 64,000 miles verified. This is the naturally-aspirated 2.5L boxer with dual AVCS on both cams — direct fit for your Outback without ECU tuning or wiring workarounds, provided years and trim match.

Complete Swap Includes:

• Engine long block (head & block assembly)
• Intake manifold
• Exhaust manifold
• Ignition coils
• Alternator
• Power steering pump
• Wiring harness
• ECU (confirm VIN compatibility before ordering — Subaru ECUs are often immobilizer-paired)

Specs:

• Engine Code: FB25
• Displacement: 2.5L (2498cc)
• Configuration: Horizontally-opposed 4-cylinder (boxer), DOHC
• Valvetrain: Dual AVCS, chain-driven (no belt to replace)
• Fuel System: Multi-port fuel injection
• Mileage: 64,000 miles
• Compatible Years: 2013-2018 Outback 2.5i (confirm trim/VIN before ordering)

Condition:
Compression and leak-down tested prior to listing. Checked for oil consumption, timing chain stretch, and AVCS solenoid response before it ships — the boxer layout makes visual inspection alone unreliable, so we test rather than eyeball it.

Fitment Note:
Engine and ECU are matched as a set. If your Outback’s immobilizer needs to sync with a new ECU, budget for a dealer or locksmith programming step — this isn’t unique to our engines, it’s a Subaru security system quirk on anything past 2013.

Shipping:
Freight shipping available, engine crated and secured for transit.
