Rb26 Injector Resistor Pack

[CruiseLiner]

hey guys im currently chasing a injector resistor pack for a rb26, but its proving difficult to find one. so im thinking do any other model skylines, or nissans use the same resistor pack????

or if anyone knows anyone with one for sale let me know plz

also i need the detonation sensor plugs section of the main engine harness because i got sold a harness without this bit, if anyone has one lying around.

thanks

Brad

A new resistor pack is about $150 from Nissan.

There's only one car I've found that uses the same resistor pack and that's the Cima from about 1989 using the VG30DET. Of course finding one of those is even harder.

The good news is that R30 Skylines and 280ZX had a resistor pack that can be adapted for the purpose. The connector is different, but if you can find a wreck with a complete loom, you can get both halves of the connector and adapt it to to the RB26 loom. The best places to get things like this are self serve wreckers.

If you get stuck I have a spare R30 pack with connector.

Hi, you can also simply buy 6 X 10 ohm resisters from JayCar or Dick Smith. Then wire them in series, one for each injector. You can do that as a pack, with the 6 resistors all shrink wrapped together, or one located at each injector.

cheers

so basically something like this wired in between the injector and main wiring harness with work with no problems at all and for the minimal cost? id imagine they would need to be well heat wrapped though. does the wattage matter at all?

seems rediculous that nissan sells them for 150 (in nz its around 250) considering the cost

As long as they're 1W ceramic type you'll be fine, most places sell them for about 70c a pop

myself and cubes went to a wrecker and got a resistor pack from an australian model Nissan R30, Does the job and have been running the GTR injectors with this for a few months now with no problems!

Exactly MR30 Skyline

Yep I run the R30 resistor pack.

Its very closely rated to that of the GTR resistor pack, from memory the GTR resistor pack measures up at 5.8ohms vs the R30 pack at 6.3ohms. The connector the resistor pack uses is the usual motormates/sprint auto shop type that sell for around $3.95. So there is absolutely no need to grab part of the loom, simply grab an Navara 8pin plug from your local auto shop and use one half of it.

I looked in to running cheap dicksmith/jaycar inline resistors but was put off after doing the watt calculations.

One won't see any problems running the cheap 5w resistors running around the street but if it hits the track or sustains high rpm for long periods of time... well.. I wouldn't risk it.

I then looked in to the 15-17w resistors and discovered they are mighty expensive. The rotor boys also have been known to make their own resistor packs and they most definitely do not use the cheap resistors, they use the 15-17w items, for six of these suckers you are look at slightly over $100. The rotor boys use 6.5ohms resistors, not 10ohms as the calcs would suggest. Interesting, ecu's have head room.

$150 for a bran new resistor pack from nissan?

They are generally $100-$150 second hand at the wreckers.

And a few pics for those interested what the R30 resistor pack and plug looks like.

I grabbed part of the loom before I discovered the local autoshops sell the exact same plug.

Also using one of these on my rb, no problems whatsoever.

mines not as clean as that one though!

[Cubes]

Yer I polished mine with brasso.

[CruiseLiner]

i got a price of $170 for a brand new resistor pack for a gtr from nissan just the other day (trade price)

[silver gts-t]

i paid $50 for a 2nd hand r30 resistor pack as recommended by cubes, works fine

what is the main issue cubes. is it simply the resistor being affected by heat??

sydneykid is pretty spot on, so sydneykd would you mind explaining cubes' theory and your opinion of it.

will the computer also be affected by the different ohms?

[Roy]

It amy not apply to everyone...but you can just buy the correct injectors in the first place

Do some googling and read up on the theory behind it your self, much more rewarding.

Yes Roy is on the ball... Just get the correct items from the word go.

By the time you by a set of gtr injectors then have them cleaned... Your only a few hundred off a set of nice shinny new items from nengun.

EDIT: Ok I've done a quick google. Explains all you need to know.

Scroll to just past half way.

For your own curiosity type in the gtr injector specs... And take very close note of what ohm resistors they recommend you use.... Nissan got it spot on from factory, well close enough.

Which is why you don't use 10ohm resistors; its not as simple as high imp resistance - low imp resistance = the resistors to use.

Don't stuff around, use what or damn close to what Nissan use, they are not silly people they know what they are doing, stick to the ~5.8 resistors, 6.3ohms from the r30 is bugger all and works perfectly fine on mine and many others.

If Nissan thought it was sufficient to use crappy little 10w resistors I'm damn sure they would have done so instead of using the bulky big arsed resistors they do.

cheers, i got my 700cc injectors for 600 so i think a resistor pack is definitley worth the trouble

[Driver]

A new resistor pack is about $150 from Nissan.

last time i checked it was well over 300buks for a resistor pack from nissan

Don't pay it then. I could do a lot better than that without even bothering to ask for trade. RRP is just that.....'recommended'.
