The 120hp EP915ECi is a great option for those who would like to add some performance without installing a turbo. We start with a brand new Rotax 912ULS as the core engine and add our 1484cc big bore kit and Fuel Injection. Some of the advantages are modern fuel injection, less maintenance, no icing or vapor lock and 2-6lbs lighter then the Rotax 912. Please call for current pricing.

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 88mm cylinders and 10.5:1 CR pistons with teflon coating
  • 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
