B18 turbo ok. Lets say 12 pounds to start low boost of course. I dont trust rc injectors web site fully so i just wanted to hear from you guys what size injectors should I use. Keep in mind i have my stock fuel pump and a walbro booster pump 255. thanks guys. I trust experience and hearing what has worked

THE BEAST

Be more specific!
440 -550 would be fine if its only daily driver and 12lbs

91 Hatch

for just 12 psi i would use 310cc prelude injectors you can run them without a fuel management, if you use 450cc you will need a fuel managment( some type of controller) to lean it out at idel

it depends on what you're gonna control them with really... if you're just planning on using a FMU setup... then go with 310s... if you want to use the VAFC hack, then use 440s. and of course if you use hondata you can use 440s too.

MORE IMPATIENT

im using 310's and i run 11 psi everyday, cars tuned for 13-14 psi and i still run pretty rich on the 310's, not sure what the duty cycle is cause im running an afc and an fmu, but it seems to be working just fine.......and i thought the HACK was just for vtec motors, if it is than your out of luck if you have an ls.......
