Honda's K20C1, better known as the engine powering the venerable Civic Type-R, is a powerful turbocharged 2.0L engine that for years has only been available as a crate engine for professional race teams. For years, Honda racing enthusiasts and fans have watched as the turbocharged K20C1 engine served as a staple in the HPD lineup of racing vehicles; powering HPD’s Type R TC and Type R TCR race cars as well as the successful F4 U.S. Championship and FR Americas Championship series.

Now, for the first time, any driver who dreams of victory can experience the adrenaline and belonging that powers Honda on the track with their very own HPD Crate Engine Package, specifically designed for easy, affordable, and reliable swap applications.

ScienceofSpeed K20C1 Civic Type-R Engine Conversion kit for S2000:

Producing in excess of 300 horsepower and 300 lbf/ft of torque, with a package weight that weighs less than the S2000 F series engine, the K20C1 is the ideal replacement for the factory engine for your S2000 race car. ScienceofSpeed has produced the only comprehensive program for installing the K20C1 into any year S2000. Available as a complete package, or as individual components, the integrated conversion kit allows the engine to be installed in the factory engine bay, for the factory S2000 transmission and other accessories to be used. The available engine controls package allows a plug-and-play experience and includes a lay-over engine harness and chassis integration harness that connects to the S2000 chassis without the need for cutting wires.
