Over a decade of proven performance and client satisfaction

  • I’ve now tuned over a dozen BCP turbos and all have been top notch. The response and power capability is simply unmatched by any other bolt on turbo for the Subaru market.

  • Amazing! Customer service was superb, they went out of their way to explain why their turbo was better than the competition in a simple, non-salesy fashion. Could not be happier with the results!

  • The spool is insane, and the power is the perfect blend of not too much but not too little. My STI should have come with this turbo from the factory.
