The overhaul uses the standard turbo housing, enlarges the compressor housing, upgrades the bearings to suit, has a larger compressor wheel and a whole raft of other refinements and modifications which I'm not allowed to go into
It will still be an OEM fitment to the exhaust manifolds (downpipes) and will need custom mapping of the ECU to match. I would also suggest an uprated oil cooler is necessary to help keep temperatures in check, and an uprated intercooler wouldn't be a bad idea either.
