For driving enthusiasts we are developing a steady stream of Katech branded components and engine and vehicle packages – from ported throttle bodies, heads and blowers; to 1000+ horsepower engines; to complete vehicle builds including suspensions, brakes, wheels, and aero.

For our motorsports customers we are building custom, extreme horsepower-and-torque race engines renown for durability. We also provide series engines built to spec, series program development and management, and track support.

For our corporate clients, we are prototyping and manufacturing current and next-generation engine components to demanding specifications, on time and on budget.

Extreme performance. Exceptional durability. Outstanding quality.

It’s who we are and what we offer: a vision to be the best.


Katech’s roots are set deeply in a legacy of success at many of the premier venues of motorsports. We became known for building engines for the famous GM Corvette Racing team that dominated the U.S. and global GT racing circuits for decades, and have never looked back.

Over the years our engines have powered a who’s who of champions worldwide – among them, A.J. Foyt, Dale Earnhardt, Dale Earnhardt Jr., Jimmy Johnson, Johnny O’Connell, Ron Fellows, and many more. Ernie Francis Jr. – the youngest Trans Am Circuit winner ever at 18 years old, and at age 20 the winner of more TA wins than any other driver – has done it all with a Katech engine.

Our awards: 28 Drivers Championships; 24 Manufacturer’s Championships; 3 Busch Grand National Championships; 3 Clevite Busch Engine Builder of the Year; 3 Pikes Peak Hill Climb Super Truck Championship, and more.

Our firsts: first modern GM V16; first E85-powered Corvette; first 500 cubic-inch small block without block modification; first LS7-powered Camaro; first V6 Victory’s in USAC Sprint Car Racing, ASA Car Racing, the All Pro Circuit; and in IMSA Kelly American Series; first V8 Turbocharged Wins in Grand Prix Hydroplane and Class 1 Offshore Racing; first 200 MPH Truck In FIA Group II, Class 9; first U.S. Chassis & Engine Combination GTU Win Since 1977; and on and on.

In February of 2020, Enginuity Power Systems (EPS) acquired Katech to use Katech’s proven testing, research and development, and manufacturing capabilities to continue to research, design and build advanced energy technologies that seek to redefine its patented engine technology, while maintaining Katech’s core business and providing new paths for growth.

There are other suppliers of performance auto parts, engines, and vehicles, but few that have proven what we offer on the track and street. If you want the best, come to Katech.
