What are the rules on engine conversions?

[Djrystofer]

I've already read up a fair bit, i.e engine may not be older than the car it is being put into, may not weigh 150 kilo more than stock car etc etc

But what are the specific restrictions on age?
Is that the date on the actual motor, or car it came out of (I.e, ls1 from 2002 VX SS is the exact same as 2003, is it still illegal to put it into a car from 2003?)
Say I were to buy a crate motor, do they came with a date of Manufacture?

Its not so much the date, its the emissions laws of that engines era.


You can get away with older engines if you run LPG.


Crate motors are different, you can use a crate engine, as long as it meets all other regulations of the car its going into. The size, and (if it can be charged or not) is determined by the weight of the car in some states. I think some have a law about it the enigne was not an option, its not aloud as a replacment.

I just found this on vicroads' website

"2. Replacement engine is not of a type offered by the vehicle manufacturer as an option for that vehicle or where alterations, or changes to the vehicle's frame or structure are made, and/or specially fabricated supports or structures are used
You will need to attend a VicRoads Customer Service Centre for an inspection of the vehicle to confirm the new engine details. You will also need to complete a Change of Vehicle Description form and provide VicRoads with:
a VASS Approval Certificate from a VicRoads Vehicle Assessment Signatory
an original receipt for the purchase of the engine as proof of ownership of the engine"

Have they changed the rules recently or something?

It does help when you tell people what state your in :-)


If thats what Vicroads state, go with what they say, or e-mail them about the age limit.
