The tuners at EDS were able to make a monster out of the Opel Astra OPC. German EDS tuning specialists are doing their best to offer Opel enthusiasts several aftermarket parts to boost the power. They are still a relatively unknown company based out of Marl, Germany, but have released a stunning kit for the most powerful Opel car, the Astra holding a 1.6-liter turbo powerplant. It was modified with a new Garret GT28 turbocharger, high performance sports exhaust system, new manifold, and ECU tuning to optimize the customizations. With these parts the Opel Astra OPC puts down 360 horsepower and 480 Nm of torque on the dyno.
