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.

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

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.

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...

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! :D

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

      R32 GTS (RB20DE) Injectors Replacement

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
