Top Mount V-Band Turbo Manifold for VW 1.8T 20V Engines

VW 1.8T 20V Top-Mount V-Band Turbo Manifold – Up to 700 HP

The newly developed Top-Mount V-Band Turbo Manifold is the perfect foundation for extreme power increases on the 1.8T 20V engine. Designed for large internal wastegate turbochargers, this manifold ensures maximum flow efficiency, fast turbo response and outstanding durability under extreme thermal load.

Thanks to the 4-into-1 runner design with large 48 mm ports, exhaust gases are directed with optimal velocity to unleash the full performance potential of Garrett and similar turbochargers. The high-temperature resistant cast stainless steel 1.4849 provides exceptional strength and crack-resistance, even under racing conditions up to 1100 °C.
