Noszle DP LT1 problems i have a nos noszle dp kit that i am trying to install on my lt1 but im haviing some problems doing so. on ls style engine the fuel injectors are straight up and down so it is easy to install. on lt1 the injectors are angled. i had to take the fuel rails apart to even get it to go one. my question is was there a lt1 specific model or do you have to do some serious modifying to get it to fit

And do not hit it with more than a 200 shot with the noszle DP kit. They pull vaccum on the injectors when spraying and go rich as hell. 150 shot they work ok. You will have to shim up your fuel rails with rod stock or something similar to keep them stable when you bolt them down.

hmmm thanks for the help. i got it to go on but i had to drill and tap new holes for the fuel rails to mount to. i used some chrome round stock to space the fuels up and had to make a creative crossover pipe. but it all fits. as far as the rich condition i have a wideband do you think i could fix it with smaller fuel pills? i was gonna start with the 200 shot and go from there so i hope i can figure out how to make the tunning correc

Problem is if you put smaller pills in your gona lean out rhe bottom. Might have to fix it in the fuel map....which in my book on a stock computer sucks. cause tis goan change with atmospheric conditions and shot size etc.....
A push system would help counter the rich big end some.

i dont think it goes rich from the lack of bottle pressure. i think what tony and daniel were saying is that the noszle itself makes a vacuum on the injector making it stick open so to speak or a longer pulse than what it is suppost to be. making it rich. thanks for the help guys. im just gonna start with the 175 see how that goes with the afr and go from there a 200 on the street is going to be a little excesive anyway. i maily like how the kit looks thats why i went with it.
