I may not be 100% correct here, but the 9k manifold won't work in the 9-5...
and in order to use the turbo from the 9000 aero (assuming it was a 5spd with the TD04) you will need to swap the compressor housing from the 9-5 onto it, and you'll also need to clock everything so that it lines up properly with everything on the 9-5.
You will need the correct lines for the TD04 as well.
08 9-5 Aero S/C
85 900 turbo - T5
