Hi all,
I recently purchased some Injector Dynamics 725cc injecotrs after my tuner reccomended them and they got a good rap whe ni asked about htem on here. Now the issue I have is that they are a high impedence saturation injector not a peak and hold low resistance injector like the stock setup so I believe I have to remove the resistor pack to make them work efficiently. I believe they will run with the resistor but I read it's best to remove it.
So.... how do I do it :lol:
Cheers,
Joe
IDs are awesome injectors yes,,agree. I use the 1000's on the NW3S Racecar.
Basically just remove the resistor pack. You don't need it any longer.
Remove the resistor and connect the wires directly. At the plus there on the firewall.
You can still use the plug to direct connect that way if you ever want to revert back you just unplug it and plug in another resistor pack.
OK so from my understanding this is the resistor pack [14922 in the pic] but it only has one plug. So when you say connect the wires directly do I jump the pins with a small loop of wire? I haven't yet had a look at the actual plug on the car but from what I can tell in the wiring diagram plug A-69 is the resistor plug and it only has 8 wires/pins.......

Yes, thats the part.
It's been a while since I did it but IIRC I removed the resistor part completely (the ceramic and all), then connected all the wires together into a solder lug. You can use something like a large battery solder lug, tin em all, put them in, solder em up then heatshrink wrap them. Then all you have to do is plug it back in and your good to go.
You're basically taking the resistor out of the circuit. When you pull it out and apart you'll see what I mean. It's easy as well as straightforward.
wait so let me get this straight. if you use ID injectors on an n/a > tt conversion, you won't have to wire injector resistors?
If you use ID injectors (or any high impedance ones) you do not use the resistor pack.
Correct as the NA does not have the resistor to begin with.
Did some further reading via the google and it all makes sense now. thanks cjbyron.

You can always integrate your own resistors into the harness but it won't be as straightforward as buying high impedance injectors to begin with. I wouldn't kick yourself over it too much. If it comes down to it just sell the ones you have now. If they are brand new you shouldn't take too much of a loss on them.
gotta bump this because i need to know where to buy 700-750cc HIGH IMPEDENCE injectors for my build. i haven't the foggiest about fitment types or anything.
Buy the ID725's like I did. Talk to STM [if they bother to reply to your emails] as they are a dealer and sell them for the EVOs.
Alternatively try this.... it comes with all hardware required [seals & cushions etc].

Length, Top O-Ring, Bottom O-Ring - 60x11xEVO
$690? wtf? they cost 2x of the low-impedence ones????
Normally the low impedance injectors work much better (Basically more accurate). I assume since these are a great injector that it costs more to manufacture them to compete with a low impedance one. I thought high impedance injectors were normally a little cheaper.
GT wizard told be about another system that works better than low impedance resistors though. I believe it uses high impedance injectors.
The price isn't more because of the impedence. It is more because they are higher quality injectors.
Most people that go to these are not doing so because they are high Z, they are switching because they want this brand of injectors due to them being so stable and everything else. They just happen to be high Z.
You can read all about why they are better at several websites.
Good luck :)
Fuel Injector Clinic sells some high-Z injectors but they are 950cc.Quote:

The standard Bosch or Siemens stuff is a bit cheaper. But for tuneability the ID is king. All sets are hand matched and checked. You know your getting a quality product with these.
I have an unused set of 3SX injector resistors. I may like to sell them because I wired in a factory resistor pack. I am not registered as a verified seller on this forum but I am on the other forum. Same user name. PM me if you might want them.
Would you mind sharing how you wired the resistor pack since I am doing a TT conversion and will be doing that as well?Quote:

I will only use the ECU and keep my N/A harness. My car does not have the resistor pack, because it is an N/A, but I bought one so I would like to know how to wire it up...Quote:

I saw that already, but I want to know how to wire up the resistor pack that came off a VR4 and not separate resistors...Quote:

To add one to an na you basically just put it in line, ill grab some pics tomorrow with more details.
Why would my car have it if it has the N/A injectors? I will check anyway...
LeRoyDL,
I would appreciate that!
Because your car is JDM. Most of the data on these sites is for usdm 3000GTs and can be wrong when talking about gtos. Always check your car first.Quote:

Well, I checked and there is no transistor pack on the fire wall or anywhere else in the engine bay that I can see. I expected that, because it doesn't make sense to install transistor pack if you don't need it. Why spend the extra money? There is a posibility that the wiring could have the connector for the transistor pack, but I doubt it. I do see a lot of connectors that are just sitting there with nothing plugged into them... I always wondered what they were for! I will take some pictures tomorrow, if I don't forget, and I will post them here to see if anyone could recognize what some of them are for.Quote:

Unless it's there and they put a blanking plug over it that bridged all the pins. Basically a single power wire goes to the resistor then through the resistor it branches off to all 6 injectors. In theory your car would have a junction somewhere that sends power to all injectors. Find that junction and wire in the tt resistor.

I wonder if it could have been there, but was removed at some point. There was something on the fire wall that I removed, but it was not a resistor pack. I will look more closely tomorrow in daylight.Quote:
