Product description:

The X8 retrofit turbo kit represents the highest legal expansion stage for the steel CEP and CZG models. As an alternative to the previously used turbo kits with tubular manifolds, this kit can also be used to exploit the full power of a steel engine on road or alcohol gasoline. However, the advantage of this expansion stage is that the proven plain bearing technology of the X8 can be used, which is superior to any ball bearing. We also have the option of registering the kit up to 707 hp, depending on the platform.
