Hey all,

As some may have read from my other threads been having some issues with me car.

I think i have narrowed the issue to some kind of a resistor or something from the injector wiring?

Pics are attached below.

Anyone able to tell me what it is? What it does?

And most important how do i go abouts fixing it?

Will i require brand new wiring for whole of injector plugs or can i get it soldier back on? etc...

Can a mechanic shop fix it or electrical shop?

I believe my injector is not working atm because of this!?

Any information will help! Thanks.

I am guessing its and RB20 motor with low impedance injectors? The part in question is a 10W resistor and there will no doubt be one for each injector. I am guessing someone felt it was easier (and definitely cheaper) to simply buy some resistors from Dick Smith than a dropping resistor pack from a GTR.

Yes, you can buy a replacement from Dick Smiths or Jaycar and wire it in although personally I believe the dropping resistor pack from a GTR is a much neater alternative.

refer to my tut about gtr injector wiring.

Instead of a resistor ballast, the previous person may have wired individual resistors (if thats what the picture is showing)

yes.. each injector has the white rectangular resistor as in the picture.

because the one pictured is broken.. would that be the cause of my #6 cyclinder not working as the injector wouldn't be squirting?

so what's the best and easiest solution?

Rekin: i had a look at your post.. pardon me being a dumbass.. LOL.. i don't quiet get what needs to be done there! "-_-

thanks guys!

Easiest solution would be to pop down to your local dick smith/jaycar etc and pick up an identical resistor and solder it into place.

Personally i'd track down a gtr resistor pack (can be bought new from Just Jap i think) and replace all the individual resistors with it. It would be a neater and probably more reliable option. Those individual resistors would surely be getting quite warm?

i got the car they way it is now so... i would agree that they would be getting hot but the car has been fine for the time i've had it.. even taken it up to bulla with no probs.

recently i pulled the AAC and Air Reg off to clean and i musta bumped the resistor by accident and musta snapped off.

SILLY QUESTION but how easy/how do you get the wires/plugs out so i can put a new resistor on? can't reach it as it's the last cylinder and down between the plenum or what every you call it and engine.

Provided you buy the correct resistor with appropriate wattage (10W shown in the photo) you should have now problems. I am guessing the resistor is a 12ohm, 10W resistor. Best to check the resistance on one of the other resistors or simply take it to Dick Smith and ask them to give you the same item.

If it is the standard plug you will need to get a screw driver on the metal spring retaining clip and gently lever it up to release the plug.

Cheers

      Stagea Front CV Axle Question

      Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...

      Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.

      Stagea Front CV Axle Question

      By dbm7 · Posted

      Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents

      I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.

      One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
