Im having a problem getting a hold of some RX7 550s,

does anyone know if there are any other injectors that are drop in for NAs?
Do the U.S sepc 550 injectors fit? Im running standalone so impedance isnt important.

I dont mind going bigger eg 800s or 1000s, I can get siemens injectors here for a good price but i dont really want to modify the fuel rail or wiring.


Help is appreciated. Thanks

was planning to do the intake manifold and upgrade the upgrade the fuel system proper then, hence just something easy is prefered for now

I noticed your answer in the other thread about domestic injectors. I tried a set of Ford injectors (same fit as LS1 I believe) and theyre longer so i assumed youd need a fuel rail as well as the o-rings?

from what i understand the LS400 440cc injectors will drop right in with no need for a resistor box or injector clips. plug and play. i have a set getting cleaned and flow tested right now ready for boost.
