Our Endurance Engine Kits for the Kawasaki STX-15F contain the same components and specifications that Team Kawasaki developed to dominate the international racing circuit. This modification produces excellent acceleration and a top speed of over 70mph using VP MS109 race fuel (Jet X).

High compression racing pistons are installed along with performance intake & exhaust camshafts. Fuel delivery, engine timing and rev limit are optimized to match the increased demands of the modified engine via a race programmed Mitsubishi ECU that plugs directly into factory wiring harness. Kit includes all necessary gaskets and detailed installation instructions. We highly recommend use of our Performance Power Filter (part# RX13085) with this package.

Complete turn-key race craft available. Click here to go to our Performance Package online for more information.
