Will the throttle body off a 2.5 bolt right on to a 06 1.8 with no modifications or tuning? If so, what years 2.5 tbs will work? Thanks

Won't work w/o modifications

 

[Bill3491]

What type of modifications? Is it worth it?

IMO, it's not worth it. Definitely not a plug and play TB. I can't imagine that the wiring is the same. IIRC, the mounting would be different as well.
