i have a 98 gt with 3:55 gears, short throw shifter, cold air intake,centerforce racing clutch,subframe connectors,strut tower brace,off road x-pipe with flowmasters, underdrive pulleys, 70mm throttle body/plenum, and springs
-i am looking to put nitrous in it. the kit i'm ordering is from nx and it supports from a 75-150 shot, i know i must purchase the purge kit seppartly, but do i also need an aftermarket fuel pump, and if so, will i need bigger injectors......thanks

 

need more info is it a dry kit or a wet kit?

 

dry kit: need 255lph or better pump and 30# injectors to be safe. but it can be done with out it./

wet kit: you need nothin the fuel solenoids supply all the fuel you need

 

he wont need 30#'ers for a 150 shot... 24's will be more than enough in that application.

24's can support around 430-450 N/A HP.
Injector lbs./hr. = horsepower x BFSC/number of cylinders
BFSC is normally .45 for an N/A engine.


So yes, if you run a 150 dry shot then 24#'ers would be a good idea.

 

everyone is gonna tell you you're fine even completely stock up to a 125 shot. so, that's what i'm gonna tell you too.

 

i'm lookin at the nx wet kit, i know i will need a fuel pump but i was making sure thats all i would need since the kit supplys everything else(except the purge kit), i was told not to go over a 100 shot to be safe

 

If you run a wet kit, the need for upgraded injectors is lessened.

 

after everything is installed, in order to tune it right, should I just get the diablo sport predator, or go to some mustang shop and get a special dyno tune and let them burn a custom chip. i heard that its pretty much the same thing with either one

p.s. how much is it to refill the bottle each time, and how often can i expect to refill it
