You need to choose your crankset, then choose the BB with a compatible axle length.

If the ID of the BB shell is less than 1.324" and the wall thickness is sufficient, you could have the house reamed out. If it is less than 1.375 (and probably 1.380"), you can probably use the Sunlite BB.
If the OP's bottom bracket is a Thun/Thompson, the ID of the shell is likely 40mm (1.575"), and the cartridge you suggest will be too small to seat in the shell.
