ADR's actually don't apply to cars before 1990. IIRC.
What you get is some beaurocrats version of job preservation.
And there-in lies a Question. Do SA give you the same grief if the car has been registered in Oz before? QLD forget about LO2 at that point.
ADRs in QLD apply back to when they first started fitting Complaince plates about 70-71
For example if you were to do an engine swap the engine has to be at least complaint to the year of manufacture of the car. So if you had a 1976 LX torana and you wanted to fit a 308 to it, the engine needs to comply with what ever was the smog code is, think it is both ARD27 and 27A, so it has to have smog heads egr etc all the vacuum stuff. If you did the same to 74 LH you don't have to do the smog stuff, but it should be compliant to what ever the code that says the idle mixture must be tamper proof. They don't do a smog check though.
My point was really that ADRs are national and what ever they want us to do with old cars should also be national in my view, so cars can go from state to state with no issue.
IIRC, 27 is the rule that governs adherence to EPA standards. This was designed to stop people putting early carburetted things into things like commodores. It really didn't cover people putting later engines into earlier cars. What it did do however was also stop Manufacturers putting an engine designed 2 years ago into current production vehicles. The intent was good, but the resultant output was crap.
The rule actually puts an onus on the regulator to certify each years engine production for a product that may be unchanged.
27A Was developed to put the onus back on the manufacturer or in our case vehicle builder to comply with the current years rules.
For us, 27 drives the rules we must comply with under 27A. For us it allows us to put earlier engines into later model cars and still comply. It actually has the authorities shaking their heads, as we have been able to circumvent the rules intention.
Basically, if we can meet or beat the emissions standards for the year of manufacture of the engine/car (whichever is later) then we can run it. With modern off the shelf technology, it is pretty easy to achieve. ( i know of an ED Sedan witha 21 stud side valve in it that complies) I guess the authorities, when they wrote the rule, never envisaged the hobbyist to spend the money required.
Bad news for them, Fuel injection and Electronic controlled engines at the time were frowned upon by the modification groups, (which just made the rule work very well) people wanted the carby they knew so well. A new generation has now moved in, and the costs of fuel injection and computer have come down a LONG way. The new generation hasn't resigned itself to the cost, they have decided they prefer the reliability and ease of operation that the new technology offers. This has seen an uptake of the technology unforseen, and driven the costs down. More and More old engines now comply with the emissions than ever before. Many of them even exceed the requirements, leaving Factory stuff in their wake....more power and Bob Brown gets a chubb at the numbers.
Keep buying injection systems guys!!!!!!! they'll be cheaper than a holley soon.
My own 1985(unleaded) patrol with a 1968 302 exceeds even todays emissions levels...........i cheated and went straight bbq fuel....................don't think i would pass noise tho :rotfl:
