I am wondering what the stock injector size is on an 03'-04' 350Z is? Also, i am planning to do my heads this year and was wondering if the stock injectors are big enough for stage 2 cams? I think the stock injectors are 335cc but also heard they were 380cc.... I need help.

2004.5 Performance Coupe
Going with Brian Crower titanium springs & retainers, Crower stainless valves, and Crower stage 2 cams, Cometic head gaskets, and possibly bigger injectors (not a daily driver).

Current Mods: Kinetix V+ plenum, Helux Throttle Body Spacer, Injen CAI, Invidia N1 catback - also - wheels and short throw

Plans: Test Pipes, Kinetix SSV Intake Manifold, Heads Built (soon), Turbonetics Single Turbo kit (i already know i need injectors w/ turbo), TurboXS Utec

If you can help please do, already tried the search, got me no where..... also any recommendations are welcome, please include info to back up your suggestions though..... Thanks a lot people.

 

Also, has anyone noticed any significant gains or positives from grounding kits. I'm thinking of making one, or some. Its 4 gauge audio grade power/ground wire, how hard could it be. And does anyone know the best places to ground the wires, or does anyone have a diagram i can refer to? Thanks Again....

 

Grounding kits have been shown to actually lose power

 

Ouch... got anything to back that up that i can read, or maybe more in depth info as to why it loses power. All i've ever read is about power gains, even though all i've read are sales pitches and so called "reviews" posted on sales pitches.... I'm going to be sure to look into it. I don't know about everyone else, but i only want whats best for my cars.

 

Do not waist your money on grounding kits or the ssv manifold as it dosent do squat for n/a.

 

your a little off on that one, their 280cc's

 

Ohh man. .grounding kits don't do nothing? jesus . .why hasn't anyone told me?? well i made this one anyway. .30 bucks about! all i noticed was a quicker pedal response, thats about it.

 

stock are 290cc

 

since we are talking injectors, does anyone know were to by stock injectors at, besides the dealship? I think mine are making the tickng noise and want opptions before i have a dealship do the work. Thanks

 

One of the hundreds of people on here that have installed aftermarket forced induction setups and remove their old stock injectors.

I'm sure most shops that do regular FI installs have tons of them lying around.
