Engine Sizing and Selection

I am in process of searching for an engine.....well two engines. I am
looking at approimately 100 to 120 horsepower engine each. I am sure that
most people would strongly recommend a reputed aircraft engines. However, I
do not want to limit myself to it. I wanted to see everything before I can
make my decision. Of course, the lighter the engine is, the better. Please
feel free to suggest anything to me. I think I just completed my research on
reputed aircraft engines. I might miss something, so don't hesitate to
mention anything that I might miss. I am currently looking and studying the
rotary engines. Any input about it? Any website about it? Is there any
converted auto engines with horsepower that I am looking for? I will get
into auto research later on, but feel free to talk about it. I will keep all
the posts to my hard drive. Anything related to engines, you better speak
out!!!!!
