Vz   POWER 135HP 


Finally a ready to install, proven, guaranteed, correctly priced turbocharged engine to bring your performance to the next level!

This is our standard conversion of the 912 ULS,  available as a complete factory new ready to install engine, or as a kit of components to perfom the installation yourself. It is basically like its little brother, but 

Ideal for homebuilders, ULM or LSA manufacturers alike!



You are getting  here a real dyno power of 135 hp with a linear output (the turbo is always engaged), not the step on the power curve typical of the 914. And best of all, you have all the needed thrust at doesn't matter what altitude, with a faster and more direct response!


Thanks to the installation of our new pistons, the compression of the 912 ULS has been put down to acceptable levels in order to make the turbo installation possible. The result is that you get a very robust engine with low compression and high power output thanks to the turbo and the bigger displacement compared to the 912 UL. 



We are giving back pilots the pleasure of the legendary smoothness of the 912 UL  80hp, compared to relative roughness of its bigger brother the 912 ULS 100hp aspirated with its original compression. Cold starts are a breeze again. Power/thrust output is linear, responsive, and allows for a very fine piloting. 


Reliability comes in part from simplicity. And here we are the winners. The absence of added electronics, no use of a TCU, will make your mechanic think he is in front of a standard 912 ULS. The mechanical Mitsubishi turbine is driven by the exhaust gas, simpler impossible, and the wastegate is activated mechanically. Maintenance is as easy and intuitive as for an aspirated engine, being still built with a "mechanical" approach and not electronical (compared to the 914 or any fuel injected system). Ideal if you operate far away from an official  service center, and if you are a strong believer that simplicity is normally the way to follow, as we certainly think.


All sub-systems like the exhaust-turbine assembly or the airbox, come with all accessories and tubing factory installed, so that your can just "plug and play". 


Being all CNC milled and TIG welded parts produced in house, we can offer to the market the best value for your money! You will not find a cheaper 135hp engine, and also not a lighter one. Depending from the countries, our complete ready to install engine costs less than a 914, still offering more power, more dependability, easier maintenance and less weight!

The turbo kit includes the following items:

  1. Airbox with tubings and oil pump pre- assembled

  2. Turbine with KN air filter

  3. Complete stainless steel exhaust with pipes (4 in 1)

  4. Rotax oil pumps (1 standard + 1 for turbine)

  5. Fuel Pressure regulator

  6. Two Pierburg fuel pumps

  7. High pressure lines and fittings

  8. Engine mount

  9. Carburetor jets

  10. 4 new pistons with gaskets


*Only the installation of the pistons requires opening the engine, thus some more confidence/knowledge.
