injector swaping

[lilchubby]

i plan on adding the nessacery equipment for a 100 shot of spray. i plan on getting bigger injectors and the boost a pump. i was thinking about the injectors that are in the gtps stock. i have heard them rated at 33 and 36 lbs but either way i htink its enough to do. my question is will they fit, and if so would i need some tuning for them to work right. i have a mail order tune already so could i just get it retuned for them? thanks in advance, forrest.

tune, yes
retune, yes they should, no charge
definately need bigger injectors

Re: injector swaping

so do u think i would have a problem with the current fuel pump or would i need to replace that as well. also anyone know about these gtp injectors?

Re: injector swaping

i think the gtps are 36ers but not sure, might want to ask in nitrous section

Re: injector swaping

36 pound injectors are way too much for a 100 shot IMO. even with tuning your car will probibly run bad when not using the nitrous at low rpm's. I would try 24 pound injectors.

and on another note, are you running a dry shot or wet shot? if its a wet shot then leave your injectors alone.

Re: injector swaping

with tuning you will be fine with GTP injectors na or on the juice. They are cheap and a good upgrade. 24# are sometimes not enough for our cars since we have 22# already. I plan on going with GTP injectors when I upgrade my motor.

are you using a dry shot?

Re: injector swaping

3.8L does not have 22 pound injectors does it? I mean, hell the LT1's run 24 pound injectors, and they have 50% the displacement.

Re: injector swaping

yea its a dry shot set up.....so assuming i get the gtp injectors will the mail order tune be good enough tuning? also would i still need the fule pump upgrade?

Re: injector swaping

all years except 93-95 got 22 # lb injectors. (not speaking of 3rd gen, or 2nd gen, etc...) the 93-95 got 17 # lbs
check the technical database

I am maxing my stock 22 # lb injectors on an N/A 3.8L ( stock cam, stock heads, etc no major mods)

Re: injector swaping

You guys forgot to mension that all the injectors are not interchangable. 2000+ doesnt use bosch style injectors.

correct! multec ll's, totally diff plug.
dont forget about the impedance....2000+ use hi impedance, (puter communications)
