For the 300 mark you would really be wanting a 19t of that family of turbos.

For the power level you are looking at LH2.4 will cope, I would suggest a wideband so you can monitor mixture.

Just set the boost to 18PSI and then keep an eye on the mixture and if its off do something about it. It sounds like you have been fed a lot of fiction with very little facts
I ran the car with just the spring wastegate which is set to 1.2 bar and the car was literally covering my dad's car in fuel as he was following me to the mot centre where they said that there's no point in mot-ing it because it was so rich.

I've got a wideband and whilst running the car at 1.8 bar the car would momentarily blip down to the low 10's if I did a pull.

It's got 550cc injectors that I was given with the turbo.
