I did once put on Sora shifters and a rear derailleur onto my Ultegra equipped roadie. In a pinch before an organized ride and my Ultegra shifters pooped out on me. The Sora shifter and rear der were flawless for a year. I only replaced them after keeping an eye on some better components. Keeping them finely tuned makes a difference. I had a bud with Ultegra that worked like junk while my Sora was great.
But my crank, I did notice a big difference. The stock Bontrager BB was notehign but a problem, and noisey clicking and ticking even after a new cartridge. I found an outboard bearing Ultegra crank online for $149. Huge difference in smoothness and stiffness. Not in speed but the bike is smooth. But the Bonti was junk after 15,000 miles.
Look up Wheelandsprocket online store on ebay. They usaully have a bunch of cranksets at good prices. I've seen 105 for $50 but the old cart setups (not outboard).
BTW, the $150 I paid for the Ultegra inlcuded the BB too! At a shop, I'd pay $200 and maybe another $60 for the BB. Plus W&S have a link where you can ask tech questions about the purchase.
