The three year 'grace' period for ICVs is the period after the start of the new ADR that you may continue to build under the old spec and still be compliant.

So, the new standard for engines (Euro 3/4?) came into effect on 01/01/05, which means that - as long as your engineer agrees - the build is complete and signed off before 31/12/07 with an engine that was compliant at 31/12/04 you should be ok.

My understanding is that the prior date for a new engine standard was 1998, so if you have your ducks in a row a new passenger car engine built between 1998-2004 will be ok until 2007

But, typically, your build will have had to have started under the supervision of an engineer during the period that the prior rules applied (i.e. before 2005) - unless you find a nice one.

The RTA is a NSW body - in Victoria its VicRoads.

The ADRs are Federal legislation - you can get a CD of the ADRs for not much$

Time to google up the lego
