how much hp can ls3 injectors handle all motor. I am goin to be making over 600hp n/a and will eventually spray a 150 shot on it to. would 52lb ls9 injectors work good for 800hp.

 

Ls3 injectors are said to be 39# Injectors. I know they are good to at least 500+ Rear wheel horse power. So they will not be your problem. Your fuel pump will! I assuming you are using a Wet kit.... Its gonna make your fuel pump work pretty hard. So as long as you have the fuel pump(s) set up right you will be fine for your goal. I suggest either a twin pump setup or the stand alone fuel system for the nitrous.

 

the ls3 injector is 42lb @ 58psi good to about 550 crank na.for the power your trying to make you should run a 52lb this will give you lots of room to grow.with the right tune should have no issues.we have new ls9 $440 a set.or we can re size yours for @200.

 

so for 200 dollars you can resize mine to 52lbs injectors. and can you size them even bigger than 52lbs for around the same money. how long is your turnaround time on resizing them.

 

ls3 can be made up to 60 lbs at 3 bar (73lb @ 58) same price. Or they can go right to 95lb @ 3bar for 300. Turn around is 3 days

 

for a turbo build what kind of power can the 73lbs support... could it handle 700rear wheel... if so i would also be interested in resizing... pm me a price and shipping info etc
