P2R CNC Ported Cylinder Heads – High-Performance Upgrade for J-Series Engines

P2R CNC-Ported Cylinder Heads are engineered for serious Honda and Acura J-Series performance builds, where airflow, reliability, and consistency matter. Each set is sold as a matched pair and is available for all J-Series engine families, including J25, J30, J32, J35, and J37.

Every cylinder head starts with our proven CNC porting program, developed through extensive flow bench testing, dyno validation, and real-world racing. These CNC-ported J-Series cylinder heads have been used on race cars worldwide, including some of the fastest J-Series-powered vehicles in the world, delivering repeatable, measurable performance gains.

Whether you’re upgrading a street-driven Honda or Acura, building an all-motor J-Series race engine, or assembling a high-boost turbo setup, P2R offers multiple cylinder head packages tailored to your performance goals.
