I'd measure the distance from the frame to the outer ring. Does the Sugino sit further out from the bb shell than the Ultegra? Or -- not quite the same thing -- does the big ring on the Sugino sit further from the bb than that on the Ultegra? One or the other would be my first guess. If so, then perhaps a bb adjustment? You probably know about that.
IME, some cranks just sit further out from the frame. I recall installing a CF Bontrager Race Lite crank in place of the Sugino XD2, and finding that a fd that worked just fine with the Sugino couldn't get nearly far enough out for the Bontrager (old 7 speed Dura Ace fd). Aside: bb/crankset/big ring/shifter woes reminds me of how I learned that, no shit! not all cranks take the same bb! I installed a new, purty Grafton on the same 122.5 or whatever the old Shimano Deore required. I got laughed at by the mechanic when I took it into the shop in tears. It didn't help that (IIRC) I was using those end-of-drops, plastic, twist grip shifters with a big neon FRED! logo on them. (And the bike was a '92 XO-1 with purple anodized Sun M14A rims.)
