Fueling & Injection - 2 questions...which injectors ls3's or 42lb'ers and how?

Ok swapping in an lq4 truck motor and using L92 heads, LS3 intake etc.

the intake came with new LS3 injectors which are rated AFAIK 36lb @ 3bar.

I have had a set of 42lb green tops (@ 3bar) in the ls1.

is the leap in technology from the ls3 injectors to the 42lb injectors big?

is the 6.5lb/hr difference for the 42lb'ers that big of a deal?

now I know with ls1 style injector I would need the different o-rings and spacers.

with the ls3 injectors all I would need is the plug adapter correct? If so what sponsor makes one?

Chadthat ls3 injector is light years above the 25yr old green top. We have the wire adapters for 39 a set and can also resize that injector up to 60 lbs. So you never have to buy new injectors..

The LS3 injector is 39 @ 4 bar (GM pressure). You will be fine with those. Easy to tune and less hassle.

I couldn't find them on your site...could you pm or post the direct link please?:emb:

if that's the case then I'll definitely go with the LS3 injectors...

I was looking at injectors around 36-42. I am doing a H/C/I swap soon and I don't know what injectors to get.

What is the 3 bar, 4 bar you are mentioning? Thanks for any help.

I just saw these are for the LS3 intake. I have a LS6.

I just saw these are for the LS3 intake. I have a LS6.a ls6 uses a full length injector 60mm oring to o ring. The ls3 injector is 40mm. you will not be able to fit the ls3 in the ls6. If you can call me I will explain all your options. 770 888 1662

should i call you too? :D

i, too, have the ls6 intake and am wanting to change injectors. currently, i have the 42 lucas (delphi, or whatever they are called).

i would like to get some 42#s or close, so long as they fit my intake. i am up for suggestions.
thanks!
