As you want faster compression with less regards to compression ratio, using bzip2, you seem to want the -1 (or --fast) option.

It can create a .tar archive and then compress it with gzip or bzip2 compression in a single command. That’s why the resulting file is a .tar.gz file or .tar.bz2 file. With BSD tar it's not possible to specify the level of compression in a similar way, as far as I have seen.
