yeah this seems to be newly added to the vicroads site.
In the case of b18c into eg, i think a VASS is no longer required, a stat dec from a mechanic will do. As long as there hasn't been any structual alterations have been done the chassis, which there won't be.
b20 in ef8 should be ok i think as well.
It states "but is equivalent in general configuration, power, mass, and emissions standard to that of the original or an optional engine for the vehicle model and can be installed without any structual alterations"
doesn't say anything about engine cc's .. as long as power, mass and emissions is equal or close to that of an optional engine (b16) and as long as there is no structual alterations ( i think this is the most important bit) then no VASS is needed i reckon.
Can anybody else confirm this???
