Viking Aircraft Engines

The company is using Honda L15-series and Mitsubishi car engines for their conversion to an aircraft application. You may buy them new from Honda but most customers opt for used engines that have been used in cars for less than 6 months or 5000 miles. After they leave the Viking factory assembly line they can be considered as a rebuilt/new aircraft engine.

The result is an engine with the latest technology for the lowest price available. The fuel economy is world class; the power to weight ratio is superb. The quality of the engines is as good as Honda gets it and to ensure reliability, Viking performs dynometer testing combined with thousands of hours of in-fight testing.

Honda / Mitsubishi manufactures these engines in thousands per year (unlike other aircraft engine manufacturers) with enough parts readily available and, more important: for a reasonable price. This guarantees the customer benefits from the absolute latest in engine technology for the best price.


Honda Based Engines

Viking 130 Engine Viking 130 Engine

The Viking 130 is as close to a Honda Fit (called Jazz in some parts of the world) car engine as possible, retaining all of its modern features. The cooling system is run with Evans liquid cooling without a pressure system and the engines are run at 66 % of the rated RPM as designed by Honda.

One of the main advantages of this engine is its low weight to power ratio compared to other engines in the market today. The fuel injection system is a GDI, gasoline direct injection. This is much like the system used in a diesel engine where fuel is injected directly into the combustion chamber. Normal gasoline fuel injection systems inject fuel just before the intake port, Rotax iS and ULPower are a good example of engines using this principle.
For those of you flying with the Viking 110 (see image above) we have the engine installation manual available.

Zenith CruZer

The Viking company Zenith CruZer is faster than any other flying at 126 kts / 154 mph TAS @ 8500 ft DA. It also has the shortest takeoff roll of any CruZer. In fact, the airplane is so powerful; it can takeoff much shorter than a full fledged CH-750 STOL airplane.


Some of the advantages of a Viking aircraft engine are:

Viking 130 EngineViking 130 Turbo Engine
  • The 2016 Honda Fit engine manual covers all engine specifics in great detail
  • The engines are Evans liquid cooled without pressure, no leaks or possible boiling
  • The engines run only at 2/3 Honda rated RPM
  • The 130 is a perfect weight for the Zenith and a host of other experimental aircraft
  • Engines are ready to bolt to the airplane as shipped
  • Cowling, engine mount and propeller available along with all other accessories
  • The 130 will outperform all other engines with 600 lb of thrust
  • The Viking has no separate external exhaust pipes, just a single muffler
  • No baffles required to direct cooling air over cylinders
  • All genuine parts are available from Honda, Mitsubishi or Viking
  • No complicated fuel return system needed
  • Worlds only GDI (gasoline direct injected) aircraft engine
  • One ignition coil per cylinder with optional dual ECU
  • The oil system is included within the engine, no external hoses or cooler
  • Variable valve lift and timing (VTEC)
  • Original Nippon Denso 40 Amp alternator
  • Custom MIL-spec wiring loom fully jacketed
  • Gearbox 1:2.33 ratio, dual overhead cam shaft, tuned intake

All of this results in an unbelievably smoooth running engine, your airframe and avionics will love you for that!


Viking engines are used and flown in a large number of aircraft ranging from Just Aircraft, Cessna, Rans, Vans RV-12 to the Zenith Aircraft CH650 and CruZer to name but a few.

Engine specifications

There are three current derivatives of Viking engines at the moment. Below an overview with the specifications, for current prices we refer you to the Viking company website.


The latest addition to the range of engines by Viking is the V90 built with a Mitsubishi 1.2 liter, fuel injected (not direct) three cylinder 90 hp model with a variable camshaft for the intake valves. Electrical power generation is done with a Nippon-Denso 40 amp alternator. It is a less expensive alternative to the Rotax 912 series engine and built around/with modern technology. See image to the right.

Engine ModelDrive TypeHorsepowerWeight
V90 (1.2 L - 3 cyl.)Geared90 hp / 67 kW150 lbs / 68 kg
V90T (1.2 L - 3 cyl. Turbo)Geared100 hp / 75 kW155 lbs / 70 kg
V130 (1.5 L)Geared130 hp / 97 kW210 lbs / 95 kg
V180T (2.0 L Turbo)Geared180 hp / 134 kW270 lbs / 122 kg

Comparing the Viking 90 with its competitors Rotax 912 80 hp and the 912iS 100 hp we see a huge advantage with the Viking 90 engine power and torque wise, see this power/torque graph.
For a power/torque comparison of a Viking 130 to an ULPower UL350iS see this image of the V130 power curve.

Turbo Engine

The new Viking turbo engine is based on the 1.5 Liter Gasoline Direct Injection Civic engine capable of 174 hp. To get an idea of the technologies used in this Honda engine, have a look at the next video: Honda Turbo 1.5 L engine animation. As of 2018, Viking also uses the 2.0 Turbo Honda Accord engine with a power output of 180 hp.

Fuel/ Electrical System

Especially developed for the experimental aircraft market, Viking has a range of fuel system components available like header tanks, filters and pumps to suit the Viking, Rotax and ULpower fuel injected engines. Click here for the latest electrical diagram.
