Katech Engineering

components capable of winning at the highest levels of competition—where durability, repeatability, and performance are demanded, not advertised. Katech engines have powered victories and championships across IROC, Trans-Am, IRL, ALMS, SCCA Pro Racing, Grand-Am, FIA GT, and NASCAR. The company was awarded NASCAR Engine Builder of the Year multiple times and recognized with the Global Motorsports Engine of the Year award. Most notably, Katech-built powerplants were instrumental in championship-winning Corvette racing programs, including six overall victories at the 24 Hours of Le Mans, one of the most demanding endurance races in the world. That race-winning experience directly shapes what Katech does today. Engineering standards refined through continuous competition at sustained high RPM, extreme heat, and long-duration load inform every engine, component, and system the company produces. From design and development through prototyping, dyno testing, validation, and manufacturing, Katech products are engineered in-house with real-world performance as the priority. Operating from a 43,000+ square-foot facility in Clinton Township, Michigan, Katech Engineering designs and manufactures high-performance engines, CNC-machined components, cylinder heads, oiling systems, and proprietary performance solutions for professional racing, track-focused builds, and serious street applications. The company also provides advanced engineering, testing, and development services for OEMs, Tier-1 suppliers, and specialty programs across automotive, motorsports, defense, marine, and industrial markets. Today, Katech Engineering operates as part of Rapson Performance Group, owned and led by longtime performance enthusiasts Mark and Lynn Rapson. Ownership is actively involved in day-to-day operations, brand direction, and long-term investment in people, equipment, and product development. The focus remains unchanged: support the engineers, respect the legacy, and continue building race-proven solutions the right way. From Le Mans-winning endurance engines to precision-built performance components, Katech Engineering delivers products shaped by competition, validated by results, and trusted by racers, manufacturers, and performance enthusiasts worldwide.
