So i got an 03 z,

Mods done
-pop charger
-plenum spacer (motordyne 5/16ths)
-stillen dual exhaust

Next on list
-greddy e managment ultimate piggyback
-stillen high flow cats
-injectors (not sure what size was thinking 650cc)
-fuel pump (was thinking 250 lph)

-f/i kit (hoping vortech v/3, but im not too picky since i just found the classifieds on this site)

So my goal is around 400 whp, you know stock internals and all)
im hoping to supercharge cause of ease of install, if i wanna get a turbo im gonna have to get one that connects at the headers or mod the exhaust but im getting sidetracked

I can probably get one of these things im planning to add a month with my income with the injectors and the pump counting as one thing, and not counting the f/i kit, im just wondering what order i should add thede things in, is there any point to the injectors and pump without the f/i kit, do i got the sizes of those 2 things right to reaxh my goal and is the greddy e managment a good choise. Also since i know its coming.. No i havent done any wheelies yet, thanks for any help guys
