Hi Everyone,

Mate of mine has built a 1000hp rb26dett and is in the process of installing it into his r32 gts...currently he is nutting out the loom and electrical side of things and wanted to know if he needed to run the factory resistor pack for the injectors? Not sure what injectors he is running, obviously something big enough to support 1000hp :P...if its important I will ask him and post it up.

Thanks to anyone that can help. :ninja:

Cheers!

Depends entirely on the ECU he is using and the type of injector drivers that ecu has.

Ecu's that can drive low impedance injectors without a resistor pack can potentially run lower pulse widths as the injector driving current is controlled more precicely. Most if not all big injectors are low impedance and would require a resistor pack if your using a power fc or something simular.

Hi GTRNUR,

He is using a Link Plus G3 ECU to run Siemens Deka 850cc injectors, here's an excerpt from the ECU manual on injector drives:

The LinkPlusG3 has eight independant injector drives allowing sequential, sequential staged, group and group staged fuel injectors.
These injection drives are designed to be used with high impedance injectors, injector ballast resistors must be wired if low impedance injectors are to be used.

So I guess he just needs to find out if the Siemens injectors he is running are low or high impedance, if they are low then use the factory resistor pack?

Cheers!

Turns out my mate wants to try and accomplish this a bit cheaper and make the resistor pack himself, does anyone know what resistors he will need and how many? (one per injector maybe?)

He's found a place in the US that sells the factory resistor packs for about $180 (not sure if AU$ or US$), does anyone have good condition one for sale that he might go instead? Otherwise I think he'll try and go the above mentioned route to save some $.

Cheers!

Not directly related but I was speaking to Ray Hall this morning about ViPec V44's and peak and hold injector drivers .

ViPec market a peak and hold driver box for the V44 because it comes with low current high impedance injector drivers .

I'm not sure if Link do them and the real question is whats cheapest , large high impedance injectors or peak and hold ones with the driver box .

They can be sourced new from Nissan or plenty of second hand ones or he can get one from a wrecker out of a MR30 (exactly the same as the gtr ones) or make up his own.

I used a gtr resistor pack the first time and made up my own the second time (purchased the 10ohm resistors from Jaycar) the ones you are after are the LARGE 10W/10ohm resistors and roughly $2 each :D

Hey Mate

I purchased a 6 ballast resistor pack for NZ$105 from NZEFI: http://www.nzefi.com/

I think Link themselves sell them for around that price too whick would work out to around AU$85+ Shipping

Probably just as easy to get the Vipec one as they should be around the same price

Good luck

Dan

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
