You can skip the E-H and porting, not necessary at this level.
Fitting a larger throttle body is not only unnecessary, it's usually brain damage. Skip it.

Stock 964/993 bridges, and updated 993 sensors. It requires removing the heads for machining.

A single 993 GT2 (-044 fuel pump) will suffice for 500hp (~450rwhp), but 2 pumps in series ala 930 is better -- plenty of pressure and volume. We've made 600rwhp on 930 fuel systems with stock Carrera fuel rails and a Carrera fuel pressure regulator.
-044 pump adapters available from TurboKraft,

500hp from a 3.3L is easy: headers, muffler, decent mid-size turbo, decent mid-size intercooler, mild cam upgrade, mild head work, EFI. If you don't make at least 450rwhp on pump gas, you're doing something wrong.
