Turbocharger Upgrade Turbocharger Audi VW Seat Skoda 2.0 TDI 125kw Stage 2 Hybrid Turbo 03G253014K + Gaskets. 38.62/52.19 mm 11+0 blades. We do machine aluminum housing and remove metal from inside so this bigger wheel would fit. To get any benefits you need to chiptune your car. Can't give any advice about the exact increase in power as it depends on each car and on different upgrades in the engine.
