You can try Honda CX500 engine, V-shaped, 2 cylinder, foure stroke water
cooled, less then 100hp. This engine was used in Honda CX 500 motor cycle. A
turbo charged engine is also available. Dirt cheap price and available on
ebay for even less then $100-200.

Here is the link for ebay if you are interested to see this engine:

Thanks! There isn't anything 2-cylinder available in this power range
(or perhaps less, all the way down to 60hp), is there? The a/c
performance can afford to be somewhat anemic, while mounting space is
at a premium.
