Emissions compliance is going to get you on the motor. You need to use a motor that is compliant to the current emissions specs which means sourcing something late model and using the ECU and assosiated emissions controls, cats etc.

You should speak to an engineer on this one or perhaps someone here can chime in with the current state of play in Victoria. You will probably find it's easiest to source a complete crate motor or pick up the drive train from a wrecked late model.

Depending on the parts you will probably be able to souce them cheaper yourself. If you are buing them from the kit manufacturer they will add their markup on them. There will be plenty of people one here with sources for parts at the right price.

As far as a mines better argument I think you will find most Cobra enthusiasts are fairly mature and realise that each kit has its plusses and minuses. There's things in each kit that I like and things I don't but I dont think it does any good to bash others cars.

Cheers
