Gtr Injector Resistor Ballast Box

[Cubes]

Hi ppls,

In an attempt to track down a injector resistor ballast box I've decided upon asking nissan.

Before I do so, Where abouts is it located?

In an attempt to track down a injector resistor ballast box I've decided upon asking nissan.

Before I do so, Where abouts is it located?

It's bolted to a bracket underneath the boost solenoid which is on the drivers side inner guard of the engine bay.

If it;s any help the part number is:

22698-05U10

Thanks Steve.

From Nissan:

Injector Dropping Resistor

$197.60

hey mate is that the resister that oyu need if you install gtr injectors into a gtst (r32) cause i gona need that soon

[Cubes]

That it is.

Second hand they appear to be quite expensive.

I gave Adelaide Jap a buzz and they quoted $175.

I said to the lady Nissan sell it for basically the same price and if thats the price they want to sell it for I'll send the extra few $$ and get a new one from Nissan.

As I was finishing off the word Nissan she hung up on me.

Bugger ... is that what they cost??? Must be cheaper to buy the right injectors in the first place...isnt it???

[Cubes]

Lol.

I'm still planning on coming across a cheap ballast.

good luck mate ive been after one for a few months i was goin to buy a new one from nissan but alls it is is one big ceramic resistor, you can buy resistors from jaycar and just wire them in series witheach injector and it would cost you $5

[discopotato03]

What about one off a Z32 or even an MR30 , if the resistance is right the old stuff is common and cheap . In fact if you got one with its loom plug it would be neat and easily replaced if need be .

Damn fine idea that.

I made a resistor pack from Jaycar 10W 10ohm ceramic resistors. Worked fine for the 2-3km before the front turbo blew at 5psi (TT conversion on RB25)

My concern was longevity as the resistors were not as large an overall package as the OEM unit. I was considering ally spacers for heat sinking to counter that. Maybe 15-20W would be preferable but I don't recall seeing them on the Jaycar site.

[Waldo]

so you think to use 15 - 20 watt resistors as they can take more heat?

[GTRgeoff]

That would be the idea. Just concerns me there is about a 30% size difference between the pack in my GTR and the one I made in the GTSt

[Waldo]

yeah you would want it to be as reliable as possible, so im with you id get 20watt 10ohm resistors so that the the heat from the engine wont affect them, but resistors heat up heaps anyways. so how long has you gts-t actually ran the 10ohm resistors cos rowdyr32 says he used 7ohm resistors

[GTRgeoff]

I recalled finding the bands for the resistance for low and high impedence, and given I was using the toyota 440cc injectors I based it on impedance of them. I think the band for high impedence was 12-14ohm and they were 3.3 ohm. More resistance meant less current and heat for the PFC to deal with as the earth switching transistors are inside.

Unfortunately the front turbo blew 2 km after i did the TT and injector mods so I have no longevity basis for my mod.

[Waldo]

do you know what resistance the gtr injectors are? is it the same as the toyota injectors

[GTRgeoff]

I just measured. 2.0-2.1ohms so that means Gareth may have been letting the ECU see too much current. Then again that depends on the source for the impedence bandwidth being correct, and I believe it was Sydneykid.

[Waldo]

i just want to get the exact right resistor so i dont melt my new power fc. thanks for helpin

Funny you should mention as I have looked in to it and will get down to the local wrecker and or pull-it parts to check a few out.

[predator]

why does the GTR use a stupid resistor pack anyway??

Why not:

a) make the injectors the correct impedence in the first place

or

B) design the ecu to accept the impedence off the bat

seems all a bit strange for Nissan to do it that way?? Must be a reason.. curious..

[SteveL]

I have one from an R30 lying around, I believe it is the same resistance as the GTR type and will try to check if I get the chance. The conector is different tho. I've offered it to people looking for resistor packs, but they seem to want the specific type.

In the past I've also made up resistor packs for injectors using readily available heavy duty items from Jaycar (they come built into a heat sink). Still got some somewhere.
