Purchasing a Core Stage turbo system

Our Core Stage turbo system does not include engine management and is not covered under our CARB EO. It is intended for competition and track vehicles that are never driven on public roads. It is also suitable for specially constructed vehicles (kit cars such as Exocets and Lotus Seven-style builds) as they fall under different emissions rules. Cars that are driven on the street, even rarely, are not eligible.

If you purchase a Core Stage kit, we will send you a link to upload photos of the car and attest that it will be installed on a vehicle not driven on public roads. If it appears the car is indeed intended for street use, we will not charge your card and the order will be cancelled. There will be a temporary hold on the funds that will be released.
