I've noticed that the Queensland Dept of Transport calculates the maximum capacity of NA'ed and turbo motors based on the original spec weight of the particular car.

I've got a 1970 beetle which I believe had an original weight of 820kg. So according to the QDOT rules, the maximum capacities are:
- Naturally aspirated (x 4 weight) = 3280cc
- Turbo (x 2.75) = 2255cc

My questions are:
1. Is there an official QDOT list of weights for each VW vehicle and year?
2. How strict is the QDOT when measuring an engine capacity (for example, if I built a 2276cc turbo engine, will I get fined or something because it's 20cc more than maximum of 2255cc?
