I was given LS3 injectors for a 2010+ camaro, 52lbs/hr, I want to know how can i run this on my 98 camaro. just by looking at it i can tell the connecting mechanism (as in the clips) is different, but it looks like it has two different cables going to it like the LS1 injector.

Also what about tuning for these, can the 98 ecm run these injectors?
they are bosch btw

I also noticed that these are shorter than the stock ls1 injectors, does this means that i would have to modify the fuel rail mounts since it would be sitting lower?

i think you can run ls3 injectors on ls1 youll need a wire adapter and different fuel rail for sure plus youll have to upgrade the pump stockls1 pump wont cut it. plus thats a lot of fuel unless you have some major mods done you dont need those injectors and youll have to retune the car for the injectors if you try to run on stock program youll wash the cylinders, if it even stays running,the 98 ecm is not very good youll probably have to upgrade to 99+ ecu to get it to tune properly

i currently have a walbro pump from racetronix and i also have HP tuner VCM suite. i am aware that it has to be tuned. I am also aware of the wiring being different. I was told i need extensions for them, but do you think i can run without the extensions if i have LS3 fuel rails? do LS3 fuel rails mount the same on the intake manifold?

Ls3 injectors are 42lb....

LS3 injectors are 42lb @ 58 psi

You need to chop out a portion of LS3 IFR table and interpolate it to fit your LS1 IFR;

you also need some of the other tables like the voltage adjustment and the small pulse adjust;

do you have tuning software (I have interpolated the tables), or will your tuner be doing this (he would already know this)...?

let me clear some things. they are 52lb injectors FOR and LS3, not stock LS3 injectors.

Basically they are LS3 style 52lb injectors

Ah, ok, thanks for clearing that up.
