Whether you need a replacement engine for an Audi RS3 or are sourcing a powertrain for another compatible vehicle, choosing the correct EA855 configuration is essential for a successful installation.

Audi EA855 2.5 TFSI Engine Specifications

The Audi EA855 is a 2.5-litre inline five-cylinder engine with a turbocharger and intercooler. Depending on the version, it uses direct fuel injection or a combination of direct and port injection. Its displacement remains approximately 2,480 cc across the main 2.5 TFSI generations.

Specifications are representative of the engine family. Actual specifications depend on the engine code, production year and vehicle application.

Compatibility / Fitment Notes

The Audi EA855 2.5 TFSI engine has been used in several Audi performance vehicles. However, not every EA855 engine is a direct replacement for every vehicle equipped with a 2.5 TFSI engine.

Potential vehicle applications include:

• Audi RS3 8P – 2.5 TFSI early generation.

• Audi RS3 8V – 2.5 TFSI, including later EA855 Evo versions.

• Audi RS3 8Y – later-generation 2.5 TFSI applications.

• Audi TT RS 8J – first-generation 2.5 TFSI.

• Audi TT RS 8S – EA855 Evo applications.

• Audi RS Q3 8U – earlier 2.5 TFSI applications.

• Audi RS Q3 F3 – later-generation 2.5 TFSI applications.

Important fitment considerations:

Before ordering an Audi EA855 replacement engine, check the following:

1. Engine code: Confirm whether your vehicle requires CEPA, CEPB, CZGB, DAZA, DNWA or another specific engine code.

2. Engine generation: Establish whether the replacement is an earlier iron-block version or a later aluminium-block EA855 Evo.

3. Mounting compatibility: Compare engine mounting points and installation requirements.

4. Transmission compatibility: Confirm compatibility with the existing gearbox and drivetrain.

5. ECU and wiring: Check engine control unit, wiring harness, sensors and electronic integration.

6. Fuel and intake systems: Verify fuel injection, intake manifold, turbocharger and fuel system configurations.

7. Emissions equipment: Compare catalytic converters, oxygen sensors and applicable emissions equipment.

Matching the engine code and original vehicle specifications is the safest approach when purchasing a replacement engine.

Engine Configuration

The Audi EA855 2.5 TFSI features an inline five-cylinder configuration. Unlike conventional four-cylinder engines, its five-cylinder layout provides a distinctive firing sequence and characteristic exhaust sound.

The engine uses a double overhead camshaft (DOHC) design with four valves per cylinder, giving it a total of 20 valves. Turbocharging and intercooling support its high-performance operation.

Later EA855 Evo versions introduced significant engineering changes, including reduced engine weight and refinements to fuel injection and internal engine components.

Engine Displacement

The EA855 2.5 TFSI has a displacement of 2,480 cc, commonly marketed as a 2.5-litre engine.

Its 82.5 mm bore and 92.8 mm stroke provide the foundation for the engine's performance characteristics. These dimensions are retained in the later-generation engine specifications.

Fuel Type

The Audi EA855 2.5 TFSI is designed to operate on petrol (gasoline), not diesel.

Depending on the engine version and market specification, fuel delivery uses direct injection or a combination of direct and port injection. Always follow the fuel requirements specified for the exact engine and vehicle.

Aspiration / Induction

The EA855 is a turbocharged engine featuring an intercooler. Its forced-induction system increases the amount of air supplied to the engine, supporting higher power output and torque.

The turbocharger, intercooler, intake system and associated sensors should be checked when purchasing a used or replacement engine.

Power Output and Torque

Power and torque vary according to the engine generation and factory calibration.

These figures represent different factory applications, not interchangeable specifications for every EA855 engine.

Years / Generation

The Audi 2.5 TFSI engine family has evolved through several generations.

• 2009–2014: Original 2.5 TFSI generation introduced in the Audi TT RS, followed by RS3 and RS Q3 applications.

• 2015–2016: Updated versions offering up to 367 PS in selected RS3 and RS Q3 applications.

• 2016 onward: EA855 Evo generation introduced with revised construction and increased performance.

• 2017–2020: EA855 Evo applications in later Audi RS3, TT RS and RS Q3 models.

• 2021 onward: Further-developed 2.5 TFSI versions, including RS3 applications producing up to 400 PS and 500 Nm.

These are broad application periods; individual engine codes and production dates should be verified against the donor vehicle.

Why Buy an Audi EA855 2.5 TFSI Replacement Engine?

Choosing the correct Audi EA855 engine can help restore the original performance and functionality of a compatible Audi RS vehicle.

The engine is particularly attractive to buyers looking for:

• A replacement for a damaged or worn 2.5 TFSI engine.
