I might be wrong, but i think my r32 gts-t s2 has a resistor pack on the pass side strut tower.

I am hoping to remove this and replace it with a gtr one that should arrive tomorrow. I also changed the plugs to bosch ones, they are much nicer and come on and off without the fuss of the standard ones.

I will be installing gtr injectors and r30 resistor pack this week before my tune on thursday and just want to make sure this is the correct way. Can anyone confirm that this pic i made is the correct wiring? :)

Also, it doesn't matter which injector is wired to each wire on the resistor pack correct?

Thanks

Dont know if this is the same thread I posted in before, but Ive been running my RB20 since May with GTR injectors with the Apexi ECU and no resistor pack. Works fine. Others have run the same for years and no problems. My car was tuned at Pro Auto here in Hobart and they have done loads of cars. None of us that race them here in Tassie run resistors, one bloke had them and took them off.

i would like to kno if this will work too, saves a lot of time with re wiring thats fo sure!!!

The resistor pack on the passenger side tower is for the fuel pump speed controller.

ok so if i put r33 gtr injectors into a rb20 and have 6 inline resistors (one for each injector)

ie dont use a resistor pack - but use jaycar or something ones instead

anyone know what which resistors i'll need?

if not i'll just measure resistance in current ones, then gtr ones and then get resistor to make up the diff?

thats the ohms - what about watts?

I strongly recommend you get your hands on a copy of the R32 GTST/GTR wiring diagram. The fact that the two engine types are on the one wiring diagram makes it very easy to suss out the wiring. You can get the diagram from rb20det.com or megalla.com

anyone have this???

edit: oooh oooh ive got the R32 engine manual pdf - which has rb20det and rb26dett

hey guys i had my GTR injectors cleaned and flow tested today all came up sweet, i replaced the pintl caps o rings and the other couple of rubbers require so all is good to go. does any one know where i can get the resistor pack from? im located in Adelaide the dude i bought the injectors off said that the injectors were low resistance does that mean that there are different types of gtr injectors? mine came off an r32 gtr. just curious.

can some one supply me with a picture of the ballast resistor pack and a picture of where to mount it in the standard position. id really appreciate it as i have no idea lol.

cheers guys BEN

Ben - no afaik all R32 GTR injectors are the same - difference is the resistance compared to R32 GTST ones

I had mine (the GTR injectors i bought for my GTST) leak and flow tested on the weekend and put them in on the weekend

(and didn't have a resistor pack so made one)

think of it like this

R32 GTST injectors have a running resistance of ROUGHLY 12 Ohms

R32 GTR injectors have a running resistance of ROUGHLY 2 Ohms

so to make the GTR ones work in the GTST you need to add another 10 Ohm

so for each injector you add a 10 Ohm resistor

ps. sorry have no pics of said GTR resistor pack as ive never seen one and dont have one :P

Does anyone know if you can run low impedence injectors in an rb20det silver top with a microtech lt12s ecu without doing the resister pack??

is there a function in the computer to set low or high impedence???

Hey roy,

Thanks for the great tutorial. Helped heaps. Was a little confused when my resistor pack only measuered 6.7 ohms but checked it against a mates gtr pack running in his car and was the same. I can see why some people say that they have low impedance injectors without the ballast resistor. Throughout this topic it is stated that you need to make up the difference which is roughly 10 ohms. Not true..... The standard resistor pack out of a 32 gtr measures only 6.7 ohms so with the gtr injectors it only comes to roughly 9.3 ohms give or take. Elsewhere I've read that high impedance injectors run between 12 and 16 ohms which makes sense because my GTST injectors measured 14.4 ohms. I installed my resistor pack and gtr injectors two days ago then drove alll the way too sydney without a problem. Just wanted to put some figures out there so people know roughly what to expect. Any questions just PM me :(

Thanks again ROY, absolute legend for the tutorial :thumbsup:

    • 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.
