Turbo, Blow-Off Valve & Wastegate

Turbo Upgrade, Blow-Off Valve and Performance Wastegate

A turbo upgrade is the modification that delivers the largest power gains on a stock turbo engine. A Dynaparts or CTS Turbo hybrid turbo lets you go beyond the limits of the original turbo with suitable ECU tuning. For the most ambitious builds, complete turbo kits are available for the EA888 (Golf GTI/R, Audi S3) and N55/B58 (BMW M135i/M235i) platforms.

The blow-off valve protects the turbo by releasing the pressure built up in the circuit when you lift off the throttle. Hubshop.fr is an official Forge Motorsport distributor and also offers GFB. Two versions available: recirculating and vent-to-atmosphere.

The external wastegate takes over boost pressure control when the original internal wastegate is no longer sufficient, and is essential on Stage 3 builds and big turbos. Available in 38mm, 44mm and 60mm.
