[opticfilms]

i need 550cc injectors used or new off a stock s15 motor.

That's kinda hard because 550's didn't come stock on s15 motors. 480's did though. Which depending on your goals (if they are modest[300whp or so] should do just fine.

This guy has some 550's though.

s15 injectors are 480cc/min
if you need 540s, you can use subaru sti injectors(2005-up)
