Hey guys,

Just finishing off wiring my 26 into my r31. I cannot fuigure out where the plug for the Injector ballast is on the 26 loom. I know its an 8 pin, im thinking that maybe my loom might be missing it?

Im scratching my head in the shed now so any replies would be helpfull

Thanks guys

It's near the relay box and the plug for the factory boost control solenoid behind the right hand headlight. It actually mounts to the same bracket as the boost control solenoid so the plug should be near that.

Thanks heaps mate, I just spent ages trying to find out what was going on.

Is the plug apart of the body loom? or the engine loom? ive got the ballast here but nowhere to plug it into

would love to get this running tomorrow guys.

from what I understand, when putting an rb26 into a gts-t you still need to wire in the resistor ballast into the 26 loom?

I don't have a common power feed for my injectors like in the 20 loom (shown in the wiring up GTR injectors to rb20 tutorial). each injector wire seems to run separately.

Surely someone knows what im on about here

Thanks

What car is the loom out of? If it's a 32GTR then the plug is on the body loom where I pointed it out. It comes out of the relay box next to two white/blue stripe wires. And yes if your running stock GTR injectors you need the resistor.

Ballast resistor needs 1x power fed in and 6x out to each injector power wire. You will find the wiring at the end of the loom near the afm plugs.

Spot on. It is the other 8 pin plug coupled to the main 8 pin engine loom plug on the front side of the passenger strut tower. You will find one of the wires is the power feed to the injectors and the other 6 are the return from the ballast resistor. I cut the plug off the ballast resistor and add a mating plug to allow it to plug into the engine loom. This means you can mount the ballast resistor somewhere behind the passenger headlight in area which should get some air flow.

Thanks for the replies guys.

I ended up opening up the loom

Each injector has 2 wires going to it - 1 of my wires was a different colour than described in in the pin-out pdf floating around. This was throwing me out at first

The wires have silver dots stamped on them:

2 dots - signal from ecu

1 dot - power

Chopped all the 1 dot power wires and wired them into the ballast resistor, taped the unused ends up and hooked up 12+ Ign to the ballast

Fired up first time ;) huge relief.

      Greg speaks wisdom. These dirty old Datsuns are only value when they are cheap. When they are not cheap, there is no value. Sounds contradictory, but it's true. We are now 20 years past the hey day of modifying cheap 90s JDM cars for small amounts of money. This is a different world. If you are rich and can afford not to care about what is effectively wasting money on an old Datto shitter, then I have no reason to argue against it. But if you are wanting to experience what we all experienced back in 2005 (and I bought my car last century!) then there is no way to do it.

      Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-

      Reading all this... hurts lol. I have an ENR34 5MT and I paid an inflated USA price for the car alone, had to do tons of preventative maintenance past that, and so I'm over $30K USD into the car already and haven't even touched power.  I wanted to +t it. Not even trying to make GTR numbers, I'd be happy with 250hp.  Can I get away with paying much less to make that happen?
