well currently the weight table rules are competely fair for turbo's (against the 6L chevs) its a great balance currently.
Your trying to help everyone else from a 5999cc capacity downwards, so in your rules you would just need to add that the new table is for n.a cars only and either make up a table for turbo and 4wd cars that makes them what they are now or make turbos etc refer to old rules.
