Depending on the year of the donor car, there are some useful bits, but generally, nothing is directly usable.
PI versus nPI, nPI aluminum versus nPI composite intake, 3.27 versus 3.55 gears.
If it is a 200 amp factory alternator, that means it is a Mitsubishi alternator with the OWC, I am not sure I have seen an upper alternator bracket for a 6G or Mitsubishi alternator and aluminum intake. Should have same connector as a 6G but be in a different spot, so wires might not be long enough. It also likely doesn't have an internal voltage regulator.
