why 75? start small and work your way up. If you don't know what it takes to run a 75 shot, you will most likely blow something up, because all the advice here won't help you to figure out if your exact car will need it.

well ive never used nitrous before...i have a turbo setup on a 92 civic hatch but nitrous is setup different and i just pretty much need to know what size injectors should i use...like 340cc or should stock 240cc be ok.

you are using the n2o with the turbo? why? do you have a large turbo that lags? if not, a 20-30 shot will work perfect for ya. and it will last a lot longer.

you got the FPR, get an AFC and a Air/fuel gauge and use that to tune your AFC. start small like +10% airflow or something. run it and shoot it and watch the gauge... then work your way up till the ---- isnt lean anymore. thats what i did. but i only got a 60 shot
