HELP!! need stock 18R-GEU ecu Injector specs.. What can be used in upgrade??

Hey,
still trying to get the 18rgeu to run and its come down to the injectors arent working any more (well 2 are kinda, and other 2 are dead).. I got them cleaned a couple of weeks ago but they are shot now thats for sure  , SO:
We need to know what the flowrates and impedences and other related info of the injectors for a stock 18rgeu ecu, to get a replacement.. Thinking maybe something from a Crown?? Old Supra?? I really need this to be up and running soon so if anyone has any specs or experience, it'd be greatly appreciated!
What injectors can i put in to my standard fuel rail that have similar specifications and will run reliably?? Even if theres a better suitable upgrade that would be a good benefit, they'd just have to run with the completely standard 18rgeu computer and otehr standard gear. Im sure there's something from a similar motor that came with the same ones???
Does anyone have a list or website which contains all the detailed injector specifications for older toyota engines?? Even a nippondenso parts book or info?
Im going to try Sleeka Spares and see what they think but i mainly just need the impedences and other specs for the injectors to try and match up an upgrade/replacement..
Cheers heaps,
car should be up and running soon, once a few things are back together..

heya man, how the motor treating you???
the 3sge 2litre injecotors will just slide straight into your fuel rail, its just that im not sure if the standard computer will handle the higher impendance injectors (around 13.6ohms)

Juzzo: Yeh havent got it to run yet, only thing still playing up is these injectors! once this problem is fixed it seems like it should run ok.. Hey what did u do to this engine before selling it to me? Cos the timing was WAY WAY out.. we couldnt believe it. Did u put the dizzy back in it after the motor was out? also, did u run the O2 sensor? im not for now, til if it gets defected, etc.
Does anyone know the impedance of the 18rgeu-type injectors? or what ratings the standard ecu can operate within??
this is really important as i really need this car up and running in the next 2 weeks and this is what is holding me up...
BansheeBuzz: sorry mate, im not about to buy a set from an anonymous person, when i have no idea whether they are OK. i thought the ones i had were fine until a couple of weeks ago..
How old are they? what are the impedances of this models injectors? What flow rate do they have?

I'm not 100% sure about this but I think that they are the same injectors. they use the same ballist resistor. Well I am using the 22re resistors on my 18rgeu injectors and they work fine. BansheeBuzz is an OK guy, He helped me out a bit with my wiring. I am using the Loom from the 22re those injectors are from.

Just a tip really.
If the dizzy looks way way out, and it hasn't been touched, you may have the ignitor wires (two wires from the dizzy to ignitor) around the wrong way. When you time the car up you want these wires (two wires only two possiblilites) on such a way that it give you the most advanced timming. Putting them on the wrong way will retard the timming by a hudge amount but will still run. Also if you do get it running on the wrong way when you rev it it will break down at high revs ie 4000+
probaly not your problem if you are just commenting on the static timing of the dizzy position.

18R-GEU injectors are the low-impedance type, so they'd be around 3-5 ohms. It is possible to use high-impedance injectors if you bypass the ballast resistor, but apparently this can cause problems (or so I've heard).

Thanks for the support Blaze.
The injectors came off a running engine, just the engine was a bit smokey due to worn rings/bore. The engine was remove for a transplant. They flow 200cc which would be very close to an 18r. You should be able to compensate with adjusting the afm if there is any difference.
They are the right impendance.
I can have them cleaned and flowed for you before i send them if you like for another $50
So heres the deal -
$50 for injectors
$50 for cleaning(if you want me to get them done)
You are best off getting them cleaned just before you are ready to install them thou

i just had a thought. The 2 injectors that went bad, are they fed from the same half or the resistor bank? if so its possible that a bad resistor bank is causing it.

Hey thanks for all the advice and info everyone, i dont think its a fualty resistor bank because we tried the VL injector on all 4 of the loom plugs and it seemed to squirt ok..as far as i can recall.
BansheeBuzz: thanks mate thats not a bad offer and i will seriously consider it seeing older injectors are fairly pricy. Its just i live in Adelaide and i would get them cleaned and tested myself here before they went in, but i wouldnt want to get a set that im not %100 certain of their compatability.
I'll think about it for a few days and then get back to you.
What other toyota engines of the 80's came with low-impedance type injectors that could operate under the same 18RGeu ecu?
Someone from PetroJect told me today they are probably 16ohm injectors(arent these high-impedance?), and having four of them makes 4 ohm? and they all fire at once? i wasnt sure if he knew anything about the 18RGe motors, is this true?

i will measure the resistance of them at work tomorrow

another point - if the resistor bank is shorted, the injectors will work for some time but will eventually burn out the coil inside the injector due to the increase in current through the injector.

sorry for late reply but remembered to check resistance of those injectors today. 2.6 ohms
