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

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
