It can usually be done without any modification to intake or exhaust -
though electronics do need to be upgraded to handle the new fuel.  These
are typically commodity items.

As an example, propane injection in diesel engines is a very economical
method of increasing power (30% hp increase in most cases). 
Essentially, all you do is install a bung in the air intake midway
between filter and manifold (turbo or otherwise), and stick the end of a
hose in that bung.  The other end of the hose is attached to the propane
tank (readily available, and DOT approved), and you install a pressure
switch to sense high-throttle conditions - so that the propane begins to
flow when you need that extra power.  It can be tuned for all sorts of
conditions.

Basically, carburetors and fuel injectors are a method of trying to make
a liquid fuel into a partial gas for easier combustion - propane, CNG,
and LPG are already gaseous.
