Part Number 3172 (This injector has the same calibration as the Siemens 3102 (55) but with a 12 ohm coil)
Static Flow Rate: 57 lb/hr @ 43.5PSI (300kPa) = 599cc/hr
Coil Resistance: 12 Ohms / High Impedance / High-Z (No ECM driver modifications required)


These injectors are the ones that camp1320 sells this is same core tha RC is now using in there 720cc injectors

thanks for the info.

so there really like 600cc's ,

if rc is using the same core, they gotta be a decent injector correct ??

these injectors work pretty well you will have machine th collar or your fuel rail if you do not get machiend ones

platinum00

can you explain the machining the collar part more. i dont fully understand it

are they to big to fit the rail or something. im assuming the collar being the part that the gasket goes around and fit in the rail ??

thanks for the info

the collar of the injector where the oring sits is way to big for any aftermarket or stock rail. The holley rail is the only one that i know makes a specific rail for specific types of injectors. Overall all you need to do is put it a lathe or enlarge the opening in your fuel rail

platinum00

seems like it would be easier to drill the rail to a bigger size hole then to do the injectors.

im trying to see how i can do this myself.

i hate having people do sh*t for me.

if you order them from camp1320 they should allready come pre machined

platinum00

good to know

i guess i will just see if they fit and then go from there.

thanks for the help
