So if you bought a suitable turbo core, it should fit into your turbine housing.
Or as said, just buy a complete unit/hybrid/whatever from a reputable turbo company. Many options.
The core was never the issue, the main problem is the stupid specific inlet and outlet from the Ford headers (triangular shaped) and outlet (5 bolts but not a standard Garrett) to the adapter routing it all to the normal circular Ford downpipe.
Here is a good read about the available combos from Garrett, however none matches the Fiesta RS inlet/outlet flanges, hence fabrication is needed.
