see sig for mods, im running stock (24lb) injectors stock fuel pump, AFPR set at 58 and injector constant set for 30lbs.
im trying to get a list of things i need to do before getting the juice. i plan on running a 100shot on my stock bottom end.
already decided on the NX wet 50-150 lt1 kit with the GEN-X2 upgrade, window switch set at 3300-6100, (i shift at 6500) stock rev limiter set at 6800.
questions:
1. do i need 30lb injector and turn the fuel pressure back to 45?
2. do i need a bigger fuel pump with my heads/cam? if so can i use an inline? or do i have to go with an intank?
3. is having heads/cam + n20 worse on my bottom end than say just a stock lt1 with 100 shot?

 

first question is why do you have it set for 30lb injectors with 24's and why is the fuel pressure so high? seems like you need the bigger injectors already.
i would highly recomend a fuel pump,external is ok,i prefer intank,much simpler.

is it worse for the bottom end? cant say. usually it isnt power that breaks things,it's the tune up and rpm that hurt things.

 

by increasing the fuel pressure to 58psi and having 24lb injectors, makes the injector spray like a 30lb'er. oh course you have to reprogram the injector constant to keep the computer from compensating.
where can find a inline pump? what brands? pricing?
thanks

with that fuel pressure the nitrous system will be extremely fat,why not just get the correct injectors? You would have to do some serious jet experimenting to get the nitrous system to work right,and unless you have experiance with nitrous,you shouldnt be doing that.

cant help ya with the inline pumps.

 

You can call NX and they can recommend the required jets for whatever fp you are running.

 

thanks for the replies.
