It's a lot of work, plan for 8hrs but it CAN be done in less and depending on your ability it CAN take more
ALOT of wires/lines and misc parts need to be removed or freed to move, everything above and around the bridge...obviously the fresh air intake tube and turbo elbow, cold side off the intercooler (unless you get a custom bridge with factory flange mount...I don't know if the EGR stuff gets in the way cuz mine was already off when I did the bridge...but then the crossover fuel lines, upper coolant pipe, wiring harness and the AC pump all have to be unsecured...
Then it gets shitty and you gotta get the bottom bolts out, then it gets even shittier when you go to put in the new bridge and have to press it into the valley to set the first two bolts (hint one front one back, opposite sides)
Then you get to put everything back together all nice and factory like
