Nismo 550cc Injectors Rb26dett -> Rb20det

[R32-PSH77]

Hey guys, might be buying some nismo injectors of a mate. he has them in his R32 GTR Rb26dett.

He is looking to upgrade to some 700cc and i want to upgrade my stockers..

seeing as how people use the GTR 444cc injectors from a gtr engine into a rb20det..;

will these nismo one fit straight in?

Cheers

yes, but dnt expect em to run to well without a resistor pack and an ecu, depending on the ecu u might not need a resistor pack though.

[R32-PSH77]

why do u need a resistor pack?? if there aftermarket injectors whats the deal?

im running a power FC..

does that help?

RB26 and RB20 are differrent impedance, so fitting GTR injectors into RB20 requires th RB26 resistor pack to match the resistance to a level the RB20 ECU wants to see.

so really i need to buy some injectors the solely fit an RB20..

Got it.

[dead32]

well depending on how much you wana spend etc, to run gtr injectors in an rb20 you need resistor pack, even the 550's in your mates gtr would have it wired with a resistor pack *from standard*... the injectors are fine to use, no you dont need a purpose built rb20 injector, just the 550's with a resistor pack..

[R32-PSH77]

i dont understand why u need an GTR resistor pack on an RB20 for these injectors to run?

does the rb20 not have its own ecu and resistor pack settings?

i dont like the idea of having to buy not only 500 worth of injectors but 200 resistor pack as well..

so does this then mean the only other option is finding rb20det spec injectors? so that ther gtr resistor pack does not have to be used.?

THe R32 GTR and GTST ecu's are designed to run high impediance injectors.

The GTR injectors are all low impediance, as not to damage the ecu's injector drivers you must run a resistor pack (~5.2-5.8ohms).

Failure to run a resistor pack will most definitely kill your ecu.
