Would you be so kind as to shoot these surfaces with an infra-red pyrometer so we can understand how hot hot is?

Only if you go through both wiring diagrams point for point and prove it to yourself. Just because the plugs are the same means nothing. 2 Subarus from the same line, on the same basic body, the same year of manufacture, can have wires swapped around in the same plug. Here you're talking about 2 completely different models (no matter how similar the two cars are, they came from different cycles and there's a million opportunities for it to change).

Dirty f**king Renault, that's why.

You can run fat drag radials because they are not about turning corners. But for decent street/circuit driving, too much width leads to baggy sidewalls which is not nice for cornering performance. You have to rein in your (completely understandable) desire for more rubber on the road to avoid the compromises you have to make elsewhere. Every time I go to buy tyres I um and ahh about putting 245s on my 8" wide wheels, and eventually punch myself in the face and stay with the 235s. As yours is a GTR, wider tyres are eminently possible - you just need 9.5 or 10" wheels.

I was a bit tongue in cheek. For racecar it is 100% allowable. A racecar is already a chop job.

245 is a little bit too wide for 8" wide wheels. 235/45 much better. If you do go 245, then 40 profile a better idea.

If it's GTR on Youtube It's 90% likely that they are install outboard. Like.... outside the car, splatter welded onto the guards.

What is a front number?

Has it run without demonstrated vacuum leaks?

So it's a Freddy. Are you sure it fits? These things (the Freddies) kinda have a history of sucking. Literally. Through the flange gaps.

Do you use inverted speaker carpet spikes on top of the jack stands? (asking for a friend).

You cannot remove the reg. You need a reg. If you remove it, you will need too remote mount it or a replacement. You cannot remove the pulsation dampener. It wont run nicely without it. If you remove it, you will need to remote mount it (and it wont work as well as it should when remote mounted. Revert FFP to stock, or go full aftermarket rail and reg. No halfway measures.

And no, you cannot make it returnless. You still need a reg, and in a returnless system, this is at the fuel pump, in the tank.

Why not just call Diesel Injection Service NT in Winnellie and ask what they can do for you? Aaaarrarararararaagh!

83 mm piston will rattle around in an 85 mm bore like a dick is a shirtsleeve. Not to mention that a 5 valve piston will not be at home against a 4 valve head. I think you mistook the original RD28 stroke for the bore measurement.

You don't have too send them out. He lives in Darwin. It may not be a big city, but it is a city, and there would have to be at least 3 workshops in town that can do fuel injection servicing, including cleaning injectors. Darwin is a major hub for heavy mining and there would have to be many may places that work on diesel engines of all scales (from road transport all the way up to 2MW Cat stationary engines). It's not difficult.

Is not the actual answer to that.... for cleaning.

The car and loom in question is >20 years old now, been through the hands of several possibly hamfisted dickheads. There are plenty of things that could go wrong, and it always turns out to be something from left field. You have to go looking for the problem. It won't jump out at you and say "Here I am!".

Well, there's your problem. There is a bus wire/wires that connect the ABS and TCS CUs to the ECU. Yoou have a wiring problem there.

Well, yeah, loom diagnosis is a process of pulling all the plugs and testing all the wires that are associated with the loom you're interested in, along with other plugs that hang from the same loom. You're looking for unexpected shorts between unrelated wires, unexpected earths, unexpected 12V (when there shouldn't be, because you've disconnected the expected power supply, etc etc.

So, the final diagnostic is to try your control unit in another car. Presuming it works in another car, then you're looking at loom/plug problems in your car.

I would Nistune the ECU, override the TCS motor/position code and forget the car ever had it. (in fact, that's exactly what I did, because Neo into R32). What's code 44 again?

You don't. Injectors come out, go in a bag, into another car, driven to the fuel injection service location of your choice.

Yes, so, injectors out, onto the cleaning and flow testing rig. Ultrasonic cleaning while pulsing with solvent supplied through them. If they do not recover - then and only then to buy replacements.

They still bring cars in.
