This is not an OEM Rotax kit and it will void the engine warranty!
Contact us for further details.

As of today, Rotax does not deliver an affordable engine with fuel injection, turbo, and this much power. We have done something about it! Here we combine the best of two worlds. The result is a beast of an engine. Our experience with this conversion is incredibly positive. We make such a conversion based on a standard Rotax 912ULS 100 HP.
Fitted to these aircraft and more: VL3 Evolution, WT-9 Dynamic, Shark, Sonex, Double Ender, Kitfox, Rans S6, C-II, Trixy Aviation Gyro, Xenon Gyro, ELA Gyro and more.
We perform the following on your engine:

  • Welded crankshaft
  • Balancing of crankshaft
  • Install EFI (Electronic Fuel Injection)
  • Install forged EP pistons with 8.5:1 CR with ceramic and Teflon coating
  • Modify the gearbox for increased power and torque
  • Install our ECU-operated boost controller
  • Install modified 914 exhaust and muffler to our spec
  • Install EP Turbo camshaft

This is not an OEM Rotax kit and it will void the engine warranty!
