I read through NCOP to see if these mods required engineering but couldn't find anything, but let me apologies in advance if it is there and I am just blind. After failing to find anything in NCOP I tried google but still failed to find. I know fuel pumps and fuel lines don't need it but have no clue about break pads and fuel injectors.

Brake pads no. Injectors themselves no....some fuel setups i think may need it, but the commercially-available-type rb inj/rail combos do not need a cert from what i recall.

Brake pads, no. Plenty of brake mods do require engineering however if all you are doing is swapping the factory pads with an aftermarket equivalent (same size, similar compound, similar performance etc), then no it doesn't need engineering. 

Fuel injectors, yes for a few reasons. Changes to the injectors with a non-standard item (either larger or smaller injectors) will have an impact on the vehicles emissions. Also, to run larger injectors you'll need an aftermarket ECU which will need to be engineered. 

This is all based on NSW, I'm not sure where you are and it might vary.

Modification to engines and/or exhausts that impacts* the emissions levels applicable to those ADRs specified for the vehicle. * ’impacts’ means an increase in emissions levels specified in the ADRs. Examples requiring certification:
• Fitting non-original valve train components.
• Fitting non-original or non equivalent carburettors or fuel injection equipment.
• Removal of bypass or emission control equipment including exhaust gas recirculation (EGR), positive crankcase ventilation (PCV), catalytic convertors, engine management sensors.
• Fitting non-original or non-equivalent air intake manifolds.
• Replacing original engine control unit.

    • I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.
    • The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?
    • I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.
    • I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
    • Yeah, I would have said the same. It makes me suggest that there are other things wrong, such that the ECU is totally unhappy with the broken sensor. The only other thought here is that maybe it is shorted, which might cause a different issue to the typical "disconnected" sensor.
