rb20 injectors are 14ohms, gtr injectors are 4 ohms hence 10 ohm is needed

I=V/R

12V / 14 ohm approx 10 ohm resistor + injector (4 ohms)

= 0.857A

P=VI

12V X 0.857A

=10.3 Watts

same as everyone else, 10W and 10 Ohm

Thanks for that mate.

How did you guys go about getting the car to run with these injectors? On the first page it sais the car may not run at all, I have a re tune booked but wanted to install these before the tune but if the car wont run with them then its gonna be kind of hard to get the car to the tuner?

edit : also i have a safc 1 installed already so is there something i can do here to make it run well enough to get it to the tuner? im trying to save a bit of cash by doing some things my self but the next tune is just for the bigger fuel pump, i wanted to get the gtr injectors in and maybe even my z32 AFM as i wont have the money to get these done by the tuner on the day.

You will almost certainly have to trailer the car there, if it runs it will be horribly rich and no doubt foul the plugs and stall multiple times, I wouldn't bother trying to drive it. If you change the AFM as well then forget about it, definitely will not run.

This is prob a stupid question, but why can't you just replace the standard injector resistor on the rb20 with the rb26 one?

You can, but most people sell them for $100, so if you can do it yourself for $10 why not?

Also the standard one doesn't use a resistor as they are normal impedance.

Its just that i saw this ebay auction which lead me to believe that the rb20 did have a resistor. Just out of curiosity what actually is this part?

hey mate ive just acquired some 33gtr injectors to go into my rb20 what resisters did you use? as i want to make one as well.

10W 10ohm from Jaycar, cost like $11 for 6 of them

Have since found a better range of boxes to house them at Altronics

As for getting the car to run I have NIStune and a Tuners license so I can get it running well enough to get to the tuners, will be a couple more weeks till I kick it in the guts though (pipes to be welded).

Its a resistor for something else and not to the injectors as it only has 2 wires

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
