If you are limited in weight and dimension, but want more power, the ULPower 260iS with its 107 hp is an excellent choice.
The UL260IS is basically an UL260i engine modified to a higher compression ratio. It runs on Avgas or Mogas 97/98.

The power and torque curve of the engine has been established by repeated dyno tests, which were performed at sea level and in weather conditions close to the ISA standard. The following graph shows the real, available power and torque coming from the crankshaft of the UL260iS engine corrected to the International Standard Atmosphere conditions at sea level.
The following graph shows the power the UL260iS engine produces at a given manifold pressure (MAP) running at a particular rpm. When taking your MAP reading and corresponding RPM at cruising speed, the graph gives you a good idea of how much (little) power your aircraft actually needs in flight.
The following graph shows the calculated available power of the UL260iS engine at different RPM settings, WOT (wide open throttle) and varying density altitude.
