NEW- STAGE 2 Hybrid kit — Now with both the compressor and turbine wheels being modified/enlarged with a balanced shaft as one assembly, all to give your 4C more boost faster. Paired with a new dyno optimized map, the tune brings the 4C up to 337hp at the crank. With 60+ dyno hours done to perfect this tune and pair it with the turbo, you can rest assured you are getting the most out of this 4C package.

This is a matched kit for the Alfa Romeo 4C, consisting of 1 hybrid turbo, and 1 Alfa Bosch based ECU unit with custom tuning accommodating the hybrid turbo’s increase air flow.

Using the factory turbo and settings as a starting point, this is the most complete upgrade kit made for the Alfa 4C and is ideally suited to 4C users looking to gain hp while retaining factory based components and retain ease of install.

Includes gaskets and oil lines needed, for a complete plug and play install on any Alfa Romeo 4C. Install takes about 5-6 hours on average. We recommend professional installation.

This kit is fully compatible with any bolt on upgrades, including intercooler, air filter, exhausts and our port & polish high flow head. Power levels from this kit do not require any specific mods to the car, but customers should consider an intercooler and suspension and brake upgrades to handle the extra power.
