Shought,
If you can make the 80G file yourself, you can tell tar the tape length option.
You will get a number of files of the specified lenght that tar can reassemble.
man tar says
Putting the files back together with cat will take forever, as cat is character orientated, not block orientated.
Since you have the file, you can untar it somewhere, than tar it back up in pieces.
--- edit ---
You don't even need to have the space to untar it to as you can pipe the output of untar into another instance of tar with the --tape-lenght option, which tars it back up.

Code:
-L, --tape-length N change tapes after writing N*1024 bytes
