A 125hp turbo and fuel injected engine that costs the same as a Rotax 914 and weighs 4lbs lighter. Intercooler is an option for increased performance. Secondary alternator is also an option.

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

We perform the following to your engine:

  • Install EFI (Electronic Fuel Injection)
  • Install our ECU operated boost controller
  • Install modified 914 exhaust and muffler to our spec
  • Lower fuel consumption
  • No vapor lock
  • No carb icing
  • No “carb-sync”
  • Save 2-6lbs vs stock configuration
  • Smoother running and far less vibration
  • Increase in power
  • Lower idle for shorter landings
  • Will start even in -35° just like a modern car due to high-pressure fuel injectors
