Probably not, I think I recall some FSA's that you could get a MTB BB for, but unless they are those or the azonics you're probably out of luck...

Yea pretty sure that you can run bmx cranks on a mtb as long as you get a euro bb. I had some on my old dj bike. Best to check with your lbs though.

Yea they sell euro bottom brackets on 02 project for $48 I think. You just need to make sure that the diameter of the spindle is either 19mm or 22mm as the bearings come in those 2 sizes only.

yes if you buy those cranks they should fit your frame, with a 22mm Spindle specific Euro BB cupset, also remember that you will need to buy a BMX style cog
