The truck intake will be better as it will build more torque, which is needed as a second gen car is heavy.

Stock injectors will be fine if you are going to stick with a stock or mild cam upgrade. Any basic electric fuel pump will do, unless you are going to go turbo, then I would check the Forced Induction forum for advice on what to go with. What trans will you be running?
