444cc GTR injectors in RB20 with Nistune, Question

So I want to use 444cc gtr injectors in my rb20det, the ecu has Nistune, and I'm wondering if I can get away with not using the Injector Resistor Ballast that the GTR uses if I get a proper tune on the car?

 

I've seen this thread:

And people say that if you get a tune you don't need the resistor, looking for a surefire answer.

Any knowledge would be appreciated so much, as 555cc injectors are cutting into my budget, and I'm quickly running out of money :(

The RB20 ECU NEEDS the resistor pack.  It is meant to drive high impedance injectors.  The 26 ECU is also meant to drive high impedance injectors.  It's more or less the same ECU.  But in order to use the low impedance injectors Nissan had to put the resistor pack on.  Why anyone would suggest that you can do without it is beyond me.  What a way to run FAR too much current through the switching transistors in the ECU.

And don't waste your time with 26 injectors. If you're going to the trouble of changing injectors, at least put in some new Bosch 1000s. It's not 2008 any more.

It may not be 2008, but maybe I'm on a budget and can't exactly afford 1000cc injectors and my engine doesn't have any injectors in it

I don't buy the "I'm on a budget" bit.  If you can't afford $600 for injectors, it's probably better to save for a bit until you have the money.  Doing mods when you don't have the funds to deal with the inevitable meltdown is a risky business.

2nd hand injectors are always risky anyway.  By the time you pay someone what they think they are worth, then get them cleaned and tested, you're 75% of the way to new ones anyway.

Just my 2c worth.

Buy new injectors, the 440cc path will end in heartache. 

How so? Whats the problem with using the 444cc injectors if I can get a set for 300, instead of paying 1000 for Nismo 555cc? It works out for my build for the short term I need them,where's the problem? Are you speaking from experience?

Why would you buy Nismo 555s for a grand when you can buy 6x brand new Bosch EV14 based injectors for ~$600 that are superior in EVERY WAY to both the shitty old GTR injectors and the Nismos?

Why buy Bosch's when I don't need anything about 555cc, I'm doing it ins budget, looking for a decently easy solution. And how are they superior exactly, find me a direct comparison and maybe I'll consider your 'advice'

And the GTR injectors may be "shitty old GTR Injectors" but not if they've been rebuilt and reconditioned.

The Nismos are old old tech.  Modern generation injectors have vastly superior spray patterns and ability to run on really low pulse widths.  If you put some effort into looking, you will find many many posts on here going on about how much better an engine will run with decent injectors.

You will find that the engine will run better with EV14 1000s than it will on the very best set of GTR/Nismos, even if they are roughly twice the capacity you need.  And it cannot get more easy than buying a set that come with the required spacers and loom converters.  Takes an extra 30s per injector to install them.

And the chances of finding a set of shitty old OEM or Nismos that have actually been anything more than given a whizz around in an ultrasonic cleaner are so close to zero that it's not funny.  By now, the originals are 20-30 years old!  If they are out of an engine, then chances are that they have been through the hands of half a dozen flat brimmers with no f**king idea, dropped, run full of tank bottoms, etc etc.  Why take that risk?  It just seems the height of foolishness.  I simply cannot imagine stripping all that part of the engine apart to put in dodgy old shit when you will only have to take it all apart again to fix whatever problem you install.

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
