hey have read the guide how to wire up the ballest resistor pack in an rb20 to run gtr injectors but i dont have the ballest resistor pack so i was wondering how i would go about wiring resistors up instead. could i wire a single 10 ohm resistor in series just after each injector plug and which cable would i do that there are two to each plug. If not would love to know how everyone has been wiring theres up, im after an easy way.

cheers

i havent tried this but was told that you would need like you said, 6 x 10ohm resistors on each of the injector signal lines. but i was also told by the person trying this that they were having trouble with the resistors constantly burning out.

I think the ballest resistor used in the r30 skylines can also be used in replacement of a gtr one. I personally just wired the resistors up inline when I had myn and never had an issue for like 8 months.

Providing the resistors are correct they should not burn out. So yeah you wire 6 of them up on the 12v live side of each injector only, the ecu then pulses ground signals to the injectors to fire them.

Personally if I had to do it again but I would probably try and source an r30 module, had I have known about them at the time.

Measure out each injector, i.e. RB20DET & RB26DETT injector. Now work out the Resistance of both, subtract the 2 and you should have a figure, that will be the resistor that you will need to use inline. Just rock up to Jaycar and they should be able to sort it out.

to work out what type of power dissipation the resistor needs to be rated at, just use P=VI, and substitute I for V/R which gives you

Power = voltage^2/R where voltage = ~13volts and R = resistance of the GT-R injector.

easy, I'm going to do this as well soon when I get my hands on GT-R injectors, Z32 AFm, and new remap....

IMO much neater than GT-R resistor pack

      Also did some work to the shed and a massive clean out of stuff. It's now got a small fab/dirty room and has helped keep shed cleaner. Built some new work benches and re organised things also got a TV out there so good having something playing while working on the cars. Got a pedestal drill and linisher off a mate that need to pick up too.

      First thought, have your current injectors flow tested. If they test fine, keep the diagnostics going. It's not the injectors. If the injectors are the issue, find some new or used (cleaned and flow tested) injectors.  While I really love a good excuse to get a modern ECU installed, just needing new injectors probably isn't a good enough reason to do so.

      A bit from column A, B and C. Mainly C   Update time, after deciding it was time to tick off a bucket list goal I finished up full time at MSR and have gotten back behind the wheel and making progress on the S15. Goal has been to drive Bathurst at an event and I have had my entry accepted for Challenge Bathurst in November. Since I don't want to go unprepared I need it running to test and get comfortable.  Been chipping away at it and started by stripping inside, getting it all cleaned and sealing some holes up. With stripping inside I removed the whole wiring loom and found a few surprises.......... its pretty butchered and shit branching and I'm not a fan of the haltech fuse boxes so it's all out and trying to come up with a plan to rewire it all either new fuse/relay box or pdm.  I haven't been happy with how I did the intercooler mounting and been wanting to tuck it up under rad support. O e issue with that is headlights will need a decent trim or get replacement covers. Took the time to mount it with some stand off's and new hardware. Stands are some m8 button bolts, washer, aluminium tube and factory radiator top mount rubbers. It's nice and solid also stiffens rad support which still requires some trimming. Bonus of factory rad mounting is used all factory hoses just need to weld a pressure cap to radiator now. Got sensor block and fuel filter mounted. Plan today is to get vac lines all sorted with push in nylon tube and design oil cooler mounting solution.  Been driving BRZ a heap and went out to Morgan Park for time attack and went pretty well for a wet day. https://youtu.be/gAlQgcQpWj4?si=kojOAOjhhX_X3AXR Getting pretty comfortable in it now and want to do a few more bits to it but restraining myself as don't need 2 race cars at the moment.

      Anyone know this frontpipe?

      By Murray_Calavera · Posted

      @sunsetR33 There is obviously a huge culture gap here. There is nothing in place like this in Australia, where if you fit a Mines branded pipe and later replace it with a Jun branded pipe, both pipes are essentially identical - BAM - huge penalties! Where is the Mines pipe?? You can't have a Jun pipe when you said you had a Mines pipe!  Makes no sense to me. Surely makes no sense to anyone else here either.  I'm sure a lot of us would agree that our registration/engineering system is pretty stupid at times, but it's not that stupid.  *** More serious question here. If you replace a factory rubber hose with a silicone hose, is the car illegally on the road now? Does it become legal if you have certification of what brand the silicone hose is? Then would it become illegal again if you replaced that silicone hose with a difference brand of silicone hose? And then would it become legal again if you had certification of the new brand of silicone hose?  I really want to know that answer to that question.

      Good you making progress with this rig. Aluminium welding is painful to learn, have you got a pedal as I found it so much easier with one. If that's the AMG I think it is, you would working with Benny?
