It is now being mandated in racing to put kevlar over the top of composite parts to stop them shattering as well.

And on the weight issue, most fabricators don't really know what they are doing when it comes to carbon and treat it like fibreglass so you end up with a product heavier than the aluminium parts anyway.

Given the recent threads it would seem the legality of the carbon bonnet seems to remain in a grey area, or at least whether or not you will be booked for it.

the two rules that apply are

ADR 12 Glare reduction in field of view.

ADR 69 Full frontal Impact occupant Protection

DOTARS told me that for the 32's ADR69 does not apply but not 100% on the 33's, they did not mention them.

The other usual rules apply with hinging and latching and scoops.

So that means that on a 32, a fibreglass bonnet, carbon fibre or aluminium bonnet is completely legal as long as there is no excessive glare and hinges and is latched correctly.

I do not see why this would be different for an R33. I would seriously contest any fines that have been issued as this has come from Department of Transport themselves.

May we have copies of this? I am a 32 owner in want of a carbon bonnet after my little hail dance incident. Let's see hail dint that ferker.

Yes, you may all have copies of this....just pay the $70 for a copy of the ADR and it's all there.

Other than that, there is a member who has a copy but I cannot remember who he was. He posted it in a reply to someone once so you might be able to do a search and ask him about it.

yeah, i would suggest that people with GTST's get the CF bonnet resprayed a normal colour so that its not as obvious to the cops?? I would just save so much hassle with the cops!!

Anyone with a GTR & a CF bonnet must really want to save every gram!! as said above the aluminium bonnets are prob .5kg heavier........other than that it sucks because the CF Bonnets look hawt!!!!

this of course excludes squizz, sorry to hear about the hail damage after the storm!!

i would love a copy of the ADRS ^^

I talked about this with Ben at Hardcore Racing today, he is a mechanical engineer and he said that mods should only be defected by accredited persons as he can certify something but any wally with a badge can defect it and then its up to you to defend it, to this end he has a deposition to the police asking to clarify this and he is in a postion to change this FU system by lobbying. As to my bonnet he told me the ADRs for that year of production (1996) apply to my car and what will pass for mine could be different for a 1997 car and so on, and as the years go on the tougher the rules, so a 1988 car will have less restrictions than a 1998 car etc.

If I find out more I will keep you posted.

Also, for bonnets, whats the point? (apart from if you have a cooling problem) as an Aluminium GTR bonnet is probably only .5 to 1kg heavier than most 'carbon' bonnets out there

there is no real point to it on a gtr as probly more then 90% of the so called "carbon fibre" bonnets in australia are fibreglass bonnets with a carbon fibre skin on them making them heavier then the aluminium and illegal,

makes it in the same category pretty much as putting diff bov's on the gtr even though the stock ones are good for more power/boost then most gtr's in qld are making and also have the advantage of being legal. :confused:

I have a wet c/f bonnet (fibreglass/cf overlay) on my z33, it came with an aluminium bonnet too but the c/f is lighter....but i just wanted it for the looks, i haven't checked to see if it's legal but my insurance company has just knocked me back for haveing it, i have a insurance broker seeing who he can find for me.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
