From Non-Running to a Powerhouse: The Custom Tuned Zafira GSi by CSC Motors & Als Autos

For all car enthusiasts, there's a riveting journey we're eager to share—a tale of transformation, dedication, and engineering finesse centered around the Zafira GSi.

The Building Process by Als Autos

Before delving into the specifics of the tuning, it's crucial to highlight the monumental efforts by Als Autos over the past six months. This Zafira GSi has been meticulously transformed from a non-running state to a fully operational marvel. Every aspect of the car underwent detailed scrutiny and enhancement.

Als Autos rebuilt the engine using forged rods, elevating its robustness and longevity. They replaced the flywheel, radiator etc to get it running again. Beyond the mechanical rebuild, they also tackled intricate wiring issues, ensuring the car not only runs but performs seamlessly. Such dedication and craftsmanship underscore the passion that went into breathing new life into this vehicle. As we say to him all the time - The car was rebuilt to specification which is what Alan is all about being a dealer trained vauxhall mechanic. His love for the Z20LEx platform helps eleviate CSC Motors to the no. 1 tuning workshop in Scotland for VXR's
