With that high compression engine? You can't even get an STC for an
alternative fuel.

Where STCs are not a consideration, high RPMs and less than full MAP can
allow the use of autogas. Performance may take a hit, and sometimes timing
must be retarded for the turbocharged engines, but it works. I ran autogas
in my first Aztec (NOT US registered!!!!!!) for years. The only difference
was that I had to turn on the boost pumps on above 7000' for vapor lock.
