Well after doing a bit of research, it would appear that there is a fair bit of difference between the costs of getting mods engineered - or engineer reports/permits.

In WA, it appears that you can get certificates for your mods when you take a car over the pits, just pay a small extra fee (aout $40?) and presto, a piece of paper with permission to have the mods on your car.

It appears that in NSW it isnt an overly expensive exercise to have these things done??? But not sure what the process is.

In SA, I have made enquiries and it appears that there are only two places in Adeliade that will do engineers reports, and look at minimum of $300 PER MOD, ie thousands to get the car done.

Does anybody have any idea what the regulations on who/where mods can get engineered, and especially, if I say get mods engineered in VIC, NSW, WA, NT, QLD - would these certificates still be valid in SA? or any other state?

If anybody knows of workshops or companies in their home states that will provide these certificates, please post up as well. With if possible price summaries:)

It may save me (and others hopefully) thousands of dollars

Thanks for any replies.

Steve

not too sure, but here in nsw im bout to get mine done, and its like 400 bucks for all mods, id say it should, www.rta.nsw.gov.au should have registered engineer's so i guess u can only find out for sure from them..

cheers...

i would be interested to know about this in QLD.

I will also ask my mate when he gets online and let you know what he is doing. (His VL is going to a 2 seater, manual to auto, roll cage, so engineering/mod plate required)

Steve, In WA I think your mixing up permits for mods like pod filters exhuast etc., with mods for ADR compliance.

Any major modification will need to be certified by an engineer to insure it complies with the ADR's. Can cost quite alot, as they need to write a report.

Luckily in WA as there are insuffucient Automotive Engineers, so most Mechanical Engineers can also write these reports, and we have one as an SAU member.

Thanks for the replies. I did a bit more research and it appears if, after extensive emissions, acceleration, braking and chassis testing, if all goes well and nothing needs modifying, would get out of it in SA for about 2k

Hopefully, SA vehicle inspectors will allow interstate certification, might be able to get out of things a bit cheaper

Paul,

Here in SA, some of the inspectors will require certificates for anything that isnt OEM. There are only two places that do engineers certification (wich can be required for anything that isnt stock), and the cheapest is the one mentioned above. For example one guy I know of had a Z32 AFM on an R32 - inspector told him he had to remove as it wasnt OEM. A guy I work with has a stock range rover, they tried, but eventually failed, to not pass his car (rego transfer from WA) because the spare wheel on the back obscured the brake light from a particular angle.

The only way to get permits for mods such as intercooler, pod, coilovers etc in SA is to get an engineers report, even then, regency can still refuse to pass the vehicle - they do things a bit different over here. You can even get the vehicle passed by regency, but you wont get permits off them - gotta be an engineers report.

And the worst part is that they wont even tell you if they think the mod will be passed (if you apply in writing on the official application) they just say you need to bring it in after its done. Then if they decide they wont allow it (once again even with engineers cert), you just gotta remove the mod or deregister the vehicle.

They dont make it easy.

I was just hoping to find a way, say if the vehicle could have reports/permits made up interstate, that regency might let it go without the exorbitant expense of full ADR compliance engineers reports.

Something you may find funny too, the engineer that I spoke too said that if the car doesnt meet emissions standards they can always fit an air pump to bring the values into line .... sort of makes a joke of the whole process, but that is an acceptable method, as long as the emissions meet specs.

Steve I thought here if it was ok you didnt need a engineers certificate to pass for things like pods,coolers, coilovers etc. I know plenty who have got through with pods/cooler. You only need a certificate for engine conversions and major mods. But it think it depends on the person.

I do believe that is the bottom line.

In WA you can get permits for mods, so when Mr Plod takes a closer look, you wont end up with a defect notice...basically this is what I want - the confidance to be able to be pulled up and not have to worry about a full regency inspection if I do.

Slip, by the sounds of it, I need to go to queensland:D

can aftermarket computers be mod plated ?

and can we drive around with them ? i have my EMS hand controller in a visible location so i dont want to get bum poked by a copper on a bad day if he see's it.

And who does mod plating in QLD. I got told of www.kcf-rallysport.com.au

they are doin work for a friend. any others?

WA has it sweeter... It cost me $50 odd for the car to be inspected at the pits (coz i got a yellow) then $25 odd for a mod permit... I got a permit for my POD, Vent to atmo BOV, exhaust, radius rods as well as a note on the permit saying that the exhaust and BOV were below acceptable dB levels... :)

The best bet in all cases is to speak with your local registration authority to find out who you should be talking too. There is so much BS bandied around in forums about what is and what is not legal because people dont bother to check with the people that know the rules for the state.

If you are in NSW you should talk to an engineering signatory, the RTA should be able to provide contact details (they have a list on their web site but I think its a bit out of date). If you are in or around Newcastle I can give details of a signatory who I am very happy with (very good with older cars).

Last time I checked a full engineering certificate with everything on the car modded (ie different engine, brakes, seats & mounts, steering, diff, wheels, seatbelts, x-members etc) was going to cost $330 but this was a year ago and there was talk of a price increase due to govt regulations.

Is there any chance of shopping around?

I had some contact with Paul Mullins who built RHR350 (Adelaide based). You could ask who did his engineering.

His contact details are at http://www.hr350.com2.info/

Its a good web page to have a look through as well.

Yeah, WA is quiet lax on most mods, the pits will allow most things no problems. Major mods like roll-cages etc need an engineers certificate.

In WA there planning on providing a rolling car test at Orbital, that will do a full emissions test for about $200. Much better than the $2000 they currently charge:(

yeh Mr Chan! I still have their official banner next to me. "Twice the Rice, Half The Price"

But the place brendan is getting his engineering thru looks alright.

My main concern is to find out if a 3L is legal in my car as it came standard with an RB20det.

Parts of the NSW guidelines....

Examples of minor (owner certified) modifications are:

*engine changes where the capacity increase is less than 15% above the maximum size engine available for the vehicle (providing no major structural modifications are necessary and where noise and/or exhaust emission ADRs apply, all standard equipment such as carburettors, exhaust systems, exhaust gas recirculating valves, oxygen sensors and catalytic convertors relating to noise and emission control are retained and operate correctly);

Engine modification

Original engine modified

Modifications to the original engine are permitted provided the following conditions are met:

*normal engine reconditioning within manufacturer’s limits is permitted;

*modifications must not affect compliance with any emission or noise related ADRs;

*all emission control equipment must be retained and functional;

*if the modifications result in a substantial increase in power, then the adequacy of other components to carry the increased power (brake performance, vehicle controllability and suspension systems etc.) as well as the vehicle’s continued compliance with the applicable ADRs must be considered.

Replacement engine

There are set engine capacity limits for a modified passenger car or passenger car derivative and these are set out in the table below. Owners should note that an engine might not be suitable even though it’s capacity falls within the specified limits. Owners are therefore advised to check details of a proposed engine conversion with an engineering signatory before commencing the work.

(I snipped out the relevant bit)

    • Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!
    • And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.
    • I have an R32 Fenix rad. It is good.
    • All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents   
    • Been a busy but productive day. Axle and hubs acquired. All fitted up after a bit of modifying. Need to sort out wider mudguards and running light reflector covers but other than that the trailer is gooood to go !!
