i just installed a turbo kit on my 96 civic lx. it has a 10lb wastegate but is only pushing 6 lbs due to the stock injectors. What size injectors do i need to install to get my 10 lbs? and if anybody has ssome let me know please

General rule of thumb. Its better and easier to remove fuel than it is to add in fuel. you should always go with bigger injectors when putting a turbo into an engine. PERIOD. also, getting a bigger fuel pump is needed as well.

what power are you looking to make?
560 will cover to about 270.
replace the fuel pump also.

Injectors wont make psi. If the wastegate has a 10psi spring in it and you are only making 6psi, then you have a 4psi pressure drop. BUT you do need injectors and a good tune to run that save.
I have 780cc injectors in my car and im about to install a set of 1000's. D16y8 t3/t4 turbo.

i can put 1000cc injectors on my d15b7 and run it all day long. it will have amazing throttle responce, but it will change verry little.reasonably 550cc inje tors are fine. 750 for upgrades later or running more psi. use the calculator i posted earlier. and it will tell you what you need. it will give it to you in terms of power goals, but if your only looking for 220 or so, then 550 will be fine.

I have my car street tuned on 780's tuned to 29-30mpg, making 3xx whp. But 550's would do fine.
