You're not emulating anything.  You're using the Cygwin port of rsync.

This is not a Cygwin question.  If you read the man page for rsync:

-e, --rsh=COMMAND
              This option allows you to choose an alternative remote
shell program to use for
              communication  between  the local and remote copies of rsync.
              [...]
              Command-line arguments are permitted in COMMAND provided
 that  COMMAND
              is  presented  to rsync  as  a single argument.
              [...]
              Some examples:

              -e 'ssh -p 2234'

              (Note that ssh users can alternately customize
site-specific  connect  options  in
               their .ssh/config file.)

So, you can either add  "-e 'ssh -p blah' " to your rsync command
line, or add a section to your ~/.ssh/config file specifying a
different port number for all outbound ssh connections to that server
(see "man ssh_config" for how to do that).  The latter would be the
preferred option if you ever do anything besides rsync that involves
ssh to that server.
