Injectors depend on your car. SVT's are 19#, non-SVT's are 16# and Cougars are 17#. Fuel pump varies with return, and non-return. ~80 something IIRC.
As for the wastegate, we will have a boost regulator to keep it at a safe boost level (8-9PSI). The maximum boost on the turbo unit depends on the engine it's on. On the 2.5L Duratec it should be 12-15PSI. We will find out the maximum "everything" soon enough.
