so i have my install coming up next fri, will be intsalling BBK full TBE headstuds fuel pump and have my throttle bodey's gaskets replaced. currently have installed is licp FMIC cat back and arc intake box. now i know i will need injectors but which ones to get. will 750's be enough or do i need to go higher. any info would be great thanks.

 

750 will work, You dont even need to go that big

 

750's would be fine. I'm running 850's on my maxed out stock turbo and am wishing I would have gotten 650's instead.

 

really? whats the stock size like 650 or something. i would have thought i would at least need 800's or similar

 

If you're already changing your injectors and you'll be tuning for the new turbo anyway, why not get 1200's and go with E-85? Is it available where you're at?

 

i thought about it but i currently dont have the money for the set up since ide have to go with the map switch alarm box and the zeitronix set up. maybe in a couple months from now plus the nearest bump station is like 40 miles away and i dont know if i would want to be having to take the trip out there everytime i needed gas.

 

now say i get 1200 injectrs now but tune for 91 only would it affect my power and tune.

 

i too have that question. i have a tbe,larger fmic, upper and lower ic piping,gsc stage 2 cams, walbro 255 and an access port. is there a general rule on horsepower vs injectors? any help would be good. thanks

 

No general rule. You have to look at IPW and IDC in your datalogs this will tell you how close you are to maxing them out.

You can scale 1200's to run on 91

 

You sir are correct.
