    Default Engine Conversion Rules

    Hi, I thought it might be useful for some people embarking or contemplating an engine conversion and may also prevent some "can i legally put xx motor in xx car?" type threads.

    [IMG]deleted[/IMG]
    Note:
    • The engine capacity to be used for rotary engines is the displacement of all rotors x 2.
    • “Original weight” is the original (unmodified) “tare weight” of the sedan version of the vehicle model fitted with the largest engine available for the model but without optional accessories such as air conditioning and tow bar.
    • The above limits do not apply to 4WD’s, light trucks and buses up to 4.5 tonne gross vehicle mass.
    • Vehicles with engines of greater capacity than that provided in the table will not be acceptable for registration as a modified
    production vehicle.

    Cheers, Black

    Nice, but I was hoping this was going to be something along the lines of "DON'T attempt an engine conversion if all you can afford to spend is the price of the front-cut" or "DON'T try to save yourself a couple hundred dollars by NOT replacing the basics, eg. timing belt, main seals, water pump etc".

    I think we could do with a list of rules like these.
