Aftermarket Turbo Kit for a 1994 Porsche Cayman

I would like to install an after market turbo kit on the 1994 Porsche Cayman with the 275HP engine. Is there a way to have it smog individually tested and approved in California without having the entire turbo installation approved by the CARB?


The turbo unit itself must be CARB approved (EO number stamped). The unit must be CARB approved for use on a 1994 Porsche Cayman, with specifically your engine configuration. So technically it's one EO number, but the component must be able to fit in with the rest of the emissions system.
