New emissiom standards were released on 1/1/03
The new satandards were enforced immediately in NSW however in VIC current builders were given 2 years to complete the vehicle.
To my understanding, the 2 years grace applies only to those people who had started building (purchased chasis) before 1/1/03
I purchased my Cobra kit in December 2002 (just made it) and so I must have it registered by the end of this year. If its Graham Docker that gave you the info then double check with him or contact Peter Ransom.

As far as I am aware, new builders will have to use 2003 motors or 1995 onwards USA motors. And yes I believe Shelby 400 is correct re: running on gas will no longer pass emmisions.
