2.0T FSI/TSI Turbo Manifold – T3 flanged

Built for FSI/TSI owners chasing serious turbo power, this cast iron T3-flanged manifold is the foundation for a proper big-turbo build on the 2.0T platform. It’s engineered to bolt up to a range of popular T3 turbochargers and pairs with an external wastegate setup for precise boost control. If you’re moving beyond stock turbo limitations and want a manifold that can handle real horsepower, this is the piece that makes it possible.

Performance & Application

This manifold is purpose-built for the 2.0T FSI turbo engine platform and designed to work with a full 2.0T FSI turbo kit. It supports a range of T3-flanged turbochargers including the GT30R, GT35R, and T04Z, giving builders flexibility in choosing the right turbo for their power goals. With an external wastegate port, boost control is handled independently of the turbo’s internal gate, allowing for more precise and consistent boost management. When paired with a GT-series turbo, this manifold has demonstrated the ability to produce 350 HP on just a little over 1 bar of boost.
