Ignore the "113mm" bb spindle length you currently have; these vary with the crankset used.

Your FSA crank is a "two-piece" design, with the bb spindle integrated with the drive side crank. FSA notes that this crank is a road crank and is compatible with 68mm bb shells only:

Are MegaExo Cranks compatible with 73mm shell width frames?

Only FSA MTB and Gravity MegaExo cranks are compatible with 73mm shell frames. All road MegaExo
cranks come with a bottom bracket compatible with 68mm shell width frames only. 70mm Italian threaded
frames require a different bottom bracket, which is available aftermarket.
