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:

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
