How much of that is in the .git/svn directory? The contents of that
directory are used to map git commits to svn revision and git versions
before 1.5.4 had a quite space consuming file format for that. The new
format is a lot better. If you want to switch completely, you can even
just delete the .git/svn directory, as that's only required as long as
you want to interact with the corresponding svn repository.

And finally, you might want to repack to repository once after the
initial import, to get a smaller repo. Something like:
git repack -a -d -f --window=100 --depth=100
