English BB internal diameter is 1.37 inches (about 34.8mm) and Italian is 36mm. Their BB shell widths are also different, English has 68 or 73 mm standards and Italian BB are 70mm. The only thing that is the same for them is the thread pitch (24 TPI).

Do you actually have an ISIS bottom bracket? What brands are your crank arms? In my local area there is a seller on Craigslist selling some Shimano Octalink splined Italian BBs.

I can also check at work for you for an used ISIS 108mm BB.
