Home of the most powerful Busa and ZX14 cylinder heads on the planet
Competition CNC specializes in CNC cylinder head porting and custom engine building for the Suzuki Hayabusa and Kawasaki ZX-14 engines among others. We offer a wide array of engineered cylinder head and camshaft packages designed to work together for peak performance. We offer 3 different size ports depending on the engine displacement and power delivery required.
We set performance and design goals to meet your specific needs. Not all engines need a stage 3 big port head. We develop the ports and combustion chambers to meet those goals by combining flow bench testing with 3D solid and surface modeling in Mastercam.
All ports are carefully designed in house to balance velocity and raw CFM air flow for each engine size. This unique combination allows us to design, develop, test cut, bench test, dyno and track test designs much faster and more accurately than ever, all in the fully equipped 8,000 square foot machine shop.
