440cc (2gen 3sgte) and 540cc (3gen 3sgte) injectors have same sizes?
540cc fits to 440 fuel rail?(same diameter part of which goes to fuel rail?-so are interchangeable?
or where I can find dimensions these two injectors (picture with dimensions)

I know that 440cc have spec this:
440cc @ 3 BAR 2.9 OHMS
but how spec are 540cc?
many thanks for reply

they are interchangeable, the only diffrence being 540CC VS 440CC.
jaroo021
and spec 540cc injectors are same as 440cc injectors?
i thing 540cc @ 3BAR 2.9OHMS? (correct me if I'm wrong)
presure2
yup.
jaroo021
and now I use 295cc -high impedence 13.3ohms and when I use 540cc low 2.9ohms i must use 4 resistors? but what power of resistors?
engine is 4age 20v black top
klue
get the OEM resistor pack and just wire it in
jaroo021
OEM resistor pack??? from what engine?
sorry but I dont understand.....
some picture with resistor pack??
klue
For the corrosponding engine your using
if you use 440cc gen 2 then use the 3sgte gen 2 injectors resistor pack
if you use the 540 gen 3 injectors then use the 3sgte gen 3 resistor pack.

You can also wire in some resistors inline with the wiring for the injecotrs
Smaay
just get low impedance injectors, done!
jaroo021
ok..many thanks.
i understand..
but where to install resistor pack or 4x resistor?between what?injector and what cable(where go this cable?)
because i have 4age 20v engine annd this engine not have resistor pack in stock-high impedence injectors...
