A 103: There are a couple ways to read it. If we assume the monk's belt gives you an equivalent monk level 5 for damage, then superior unarmed strike stacks to level 9 (1d10). Improved natural attack bumps that up one dice size to 2d8.
If we assume the belt doesn't give you monk abiliites, then go by the table for superior unarmed strike, which at level 12 is 1d10. Bump up with INA for 2d8 just like before.
At your current level, it works out to be the same both ways. One you're at level 16, going by the second interpretation your damage improves to 3d6.
