I have decided to upgrade my cams to stage 2, NPI blower cams for my car
(98 gt with P1SC). I realize i need other components upgraded to compliment the cams, my questions are:

1. what size injectors will i need? (stock now)
2. what type, manuf, size, blow-thru maf should i go with? (stock now)
3. what type of fuel pump should i upgrade to? the car does have an aftermarket in-line pump, although my tuner said it is already is barely keeping up with the fueling needs.
4. is there anything else that i will need?

I know i will need to have it re-tuned.
