Honda tried this with the Sports Modulo program in Japan. Factory-backed performance parts with warranty. It seems it couldn't compete with the aftermarket, as the costs were higher for the Modulo parts versus established aftermarket like HKS, Greddy, etc. To me, the answer may be to integrate those large aftermarket makers into part subcontractors for Honda. So, you're getting a HKS turbo system that has been developed by HKS and then tested and certified by Honda and sold as a Honda Modulo part.
