What Is the FA20 Engine?

The FA20 Engine is the 2.0-liter horizontally opposed four-cylinder developed by Subaru and Toyota, used in the BRZ, FR-S and, as the turbocharged FA20DIT, the WRX.

Like any engine, it should be matched to your vehicle by model year, trim, and configuration. For a general overview of how this component works, see the Wikipedia entry on the internal combustion engine.

How to Confirm Fitment Before You Buy

Choosing the wrong engine is a costly mistake. Before ordering, run through these checks:

• Match the engine code, or the eighth character of your VIN, with the engine options listed for your vehicle.
• Confirm the model year, trim, displacement, and fuel type (gasoline, diesel, or hybrid).
• Note features that affect compatibility, such as turbocharging, direct injection, or variable valve timing.
• Check whether you also need related components such as the intake, wiring harness, sensors, or ECU.
• Ask our team to confirm availability, included components, and condition details before you order.

You can decode your VIN with the NHTSA VIN decoder and check for open safety recalls on the NHTSA recalls page before you start a major repair.

Signs You May Need a Replacement Engine

Not sure whether you need a replacement engine? Watch for these warning signs:

• Persistent knocking, ticking, or tapping noises from inside the engine
• Excessive oil consumption, oil leaks, or blue smoke from the exhaust
• Repeated overheating or coolant loss without an external leak
• Rough running, misfires, or low compression on one or more cylinders
• Metal particles in the oil, or a check engine light that returns after repairs

These symptoms can point to serious internal wear, but smaller faults can cause them too, so have a qualified technician diagnose the vehicle before you commit to a replacement.
