A couple of the Gen V bolts are different enough that you will need new ones, but most can be reused.
Gen III
1 - M8x1.25x85
1 - M8x1.25x65
8 - M8x1.25x45
Gen V
1 - M8x1.25x140
1 - M8x1.25x120
1 - M8x1.25x80
7 - M8x1.25x40
You will also need to deal with the PCV system. You need to drill and tap the brass plug on the bottom of the throttle body and run a line from there up to the inlet of the PCV system on the blower.
You'll need to block off the inlet for the Gen V's EVAP system, since the Gen III uses a totally different system.
