Hey guys, just wondering if anyone knows the flow rates for stock g35 injectors. or even the HR version? I drive a maxima but will be making a few modifications to my N/A setup and I have a feeling a slightly bigger injector will help me out. I know the 350Z injectors are slightly bigger than my stockers (315cc@3.5bar) but i would like to upgrade to at least 335 or 350cc. If the g35 are same as the z it will make my search a little easier as I can look for either/or. Thanks in advance.

 

Why would you need bigger injectors? Your stockers should be good enough, no?

 

I got 400 whp out my stock injectors. You don't need to upgrade. I think stock injectors for a g35 are 330cc.

 

mine are only 315cc.

 

U can try bigger injectors but I don't think they are necessary for your application.

 

well, I'm going to be putting a bigger diameter MAF tube and gutting my intake manifold which should increase the air volume. I would prefer to use a short pulse on a big injector than a long pulse on a small injector. I'm not sure how long a pulse my stock injectors can handle to add fuel to the mixture. I'm also not sure how much control the emanage blue has. I think it's easier to reduce the pulse and run the larger ones at a lower volume.

 

You are a long way from needing new injectors. Start worrying about injectors at the 400whp range if you want to spend some money get rid of the E-Manage and get a better ecu! ANYTHING is better than an E-Manage. E-manages dont control larger injectors worth a **** in my experiance.

 

 

On the track the stock injectors are running high in their duty cycle and can generate alot of heat (higher chance for failure or improper spray patterns). The bigger injector has a higher duty cycle, thus runs cooler at sustained high RPM use.

 

Sylvan lake and i both have 400 whp + and run 1/4 mile drag with no problem on stock injectors. I have a haltech and he is running a s.s box. Use the search button and you will see people dont like the emanage. If you want injectors that bad go to the marketplace and buy some. There are always some in there. Go buy some 440cc's. Your money
