Confirming ISIS bottom bracket size for OZ

[Thunderchild]

I have a 113mm x 73mm square taper on my oz.  All I own are square taper.  I am helping a bud build up his Oz he purchased on Ebay.  If he switches to ISIS cranks, is the bottom bracket the same width, 113, or does it change a bit from the square taper?

Thanks

i think there are only 2 sizes of isis bb`s 113mm axle length for double cranks and 118mm for triples after that you just need the right shell width and away you go.
