hey guys i really need to know how to wire inline resitors in my rb20 for gtr injectors to work with my power fc, i need to know exactly what resistors i need to put in and also what resistance the circuit has to be to make them run, i dont want to blow up my precious power fc,

thanx for al you help

regards luke

There was a guide on how to make them.. was very easy and would cost you about $5 in parts.. I believe it had to do with wiring a resistor on the "active" line of each injector. It was in a stupid place on here (wanted section??) and can't find it for the life of me anymore.

so if i just get a gtr ballast resistor i just plug that into the loom do i and it will work perfect?

Its not plug in, it requires soldering whether you use the Nissan ballast resistor or make your own usign resistors from Jaycar.

If you look in the tutorial section i did a thread to help ppl get started. Outside of that it is easy to cut into theloom and solder it all up, just take it slow and triple check everything. If you were in Melb id be happy to do it, including installing injetors its about a 6hr job from start to finish, including removing coil pack covers, inlet piping, taping up the loom etc etc

Mine was 13 ohms with the GTR resistor pack in and 3.5 ohns with resistor pack out.;)

Thanks SK, In the workshop manual it states 5k for the resistor pack :confused:

even so 13k seems a little high if the ecu has the same mosfet transistors as the rb20 ecu

Cant remember, i did measure it to check that i had it all wired up correctly. Easisest thing to do is when you are removing the injectors just check the resistance of the GTR injector with the RB20 injector.  

I seem to remember the ballast resistor was about 5-6ohms

well that confirms what the workshop manual states...

so if i simply get a gtr ballast box, i just have to cut and solder each injector positive feed into each of the wires coming out of the ballast box?, if i do it the other way as in wireing resitors inline, do i just cut the main feed to the injector and wire an inline resitor into it, if so what size resitor is needed to do this.

you are best off getting the heavy duty ceramic ones - I think they are the 1watt.. they are big and square. I'd say if you wrapped that in plenty of electrical tape, and soldered properly you shouldn't have a problem I wouldn't think.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
