true but the orefice deal is a little weird, i dont hav a drill bit that small. an aquarium valve will work the same and is adjustable.
i wouldnt trust my motor to a cheap setup.
hanging springs on the wastegate is another cheese mod that i wouldnt risk doing.

pt turbos are finicky, if you go overboost you will cause a retarded ignition reducing power. you'd need a map clamp for starters.
stage 1 is the best idea to start with then move up from there.
