Turbo Manifold Audi EA839 (B9 3.0 V6)

EA839 Turbo Manifold Suits B9 S4&S5 Developed for turbocharged Audi 3.0 V6, the Walton Motorsport EA839 Turbo Manifold provides a modern V-band turbo platform for owners looking to move beyond the limitations of the factory turbo system. Rather than being tied to an OEM-style replacement turbocharger, the manifold allows the 3.0-litre EA839 engine to be paired with a range of modern performance turbos, creating a foundation for anything from a responsive street setup through to a more extensively developed high-power S4 or S5. EA839 Turbo Manifold - Modern V-Band Turbo Options The manifold is available with a Garrett V-band turbo inlet suitable for G25, G30 and G35 turbochargers, along with compatible Turbosmart Frame B and HPT Frame 2 options. This provides a useful range of turbo sizing for the 3.0-litre V6 engine. A smaller turbo can be selected where response, transient performance and everyday drivability are priorities, while larger options provide greater airflow for builds targeting substantially more power. The right choice should be based on the complete engine combination and intended powerband rather than simply choosing the largest turbocharger available. VAG V6 Turbo Manifold - Wastegate & Boost Control The manifold features a 50 mm external wastegate port, supplied with a flange fitted. Building Your Audi 3.0 V6 Turbo System This manifold should be considered the foundation of a custom performance turbo system, rather than a simple bolt-on replacement for the standard Audi turbocharger. Turbocharger, wastegate, downpipe, intake, charge system, fuel system and ECU calibration should all be specified around the intended performance level of the vehicle. For a road-driven S4/S5, that may mean deliberately prioritising response and a broad usable torque curve. For more extensively developed builds, the available turbo range provides scope to increase airflow and power capability considerably beyond the original turbo arrangement. If you're planning a turbo upgrade for your Audi V6 and aren't sure which turbocharger or wastegate configuration best suits the combination, contact Walton Motorsport before ordering and we can help establish the appropriate specification.
