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

 

Dude i put this in the wrong section op please lock i belive this belongs in f/i

 

If you want to run with 400whp. you should not be on stock internals.
If you want it to last at least.

Before you do more performance mods. Id say you focus on suspension.
Get some good coilovers, some upper arms and tie rods. doing it all right the first time. maybe some sway bars. THEN turn your focus into getting more power.
pointless to have all of that if you cant put it to the ground
