what do you need to run Tial 3071s? injectors? upgraded fuel pump?
are the 3076r better?

 

You would ned injectors, pump, and tune to work with this kit. the 3076's are not better so to say it really all depends what you are using the car for and your power goals. 3076's really are for built motor cars or people looking to push the stock motor to its limits.
