Gtr Injectors For Rb20

[Sexual_32]

Hey guys, as ive been told by numerous people, a cheap injector upgrade is to go the gtr injectors for the rb20s.. However ive been told u need the rb26 resistor pack to run these?

Can anyone confirm this and tell me why?

Ive come across a set but the previous owner had them on his 20 and said he wasnt using a resistor pack? Why?

Thanks,

Steve.

Its becuase the impedance of the 2 injectors differs:

RB20det is low impedance

RB26 is high impedance

The resistor pack lowers the impedance of the GTR injectors to match (as close as it can) that of the original injectors.

However this shouldn't effect the firing rate, its more to save the injector drivers on the ECU from burning out.

You don't need a resistor pack - i don't have one with my GTR injectors, but it would ensure the longevity of the ECU by having one.

wat if i was running aftermarket ecu?

wat if i was running aftermarket ecu?

As long as you can set the impedance on your A/M ECU, it wont be an issue (you wont need a resistor pack)

thanks mate

Dont attempt to run it without the GTR resistor pack or properly set up resistors

I burnt out the injector driver in my new Power FC from stuffing up the resistors

Mine only lasted a couple of days before blowing...

Hopefully can be fixed and I will be back up and running soon

thanks for the tip dano

yes you can use the gtr injectors ..

but get ya self a resistor park from a 2.4e r30 skyline .. same resistor pack (gtr) diffrent plug .

and make sure they are cleaned and flow tested as most gtr injectors have been sitting so long the dont flow 444cc

You can also just wire the appropriate sized resistors into the loom, it's what people do when they either can't find a resistor pack or the chumps want too much for them. Have a search and you should find the type you need.

People want stupid money for gtr resistor packs, just wire the resistors into the loom. Cost all of $5

Has anyone done a DIY thread on doing it like that? I have had a good rearch but every result came back explaing how to use the GTR Resistor packs

I used 6 10ohm resistors from jaycar wired inline but it still somehow fried the injector driver in the ECU...

[bubba]

Pretty sure there was a thread stating what size resistors to use.. cbf finding it though.. got better things to do to waste time at work

If you cant suss it out after reading this i suggest you get somebody to do it for you

And Sexual 300. What front bar is that you are running?

Well whaddaya know?! it was in the DIY/Tut section!

I used that exact guide originally however found using 5r6 ohm resistors worked best next to the ballast pack.

Then did away with that and the resistors altogether, my stock ECU has worked over a year with no resistors - go Nissan!
