2 - what does the chart mean in terms of motor swaps from those cars - particularly the group mentioned above where they appear fully legal as doner engines to a swap per the ST category rules, or those such as the 2AZ-FE + TRD supercharger from the Scion Tc which could be directly ported to a coroola / matrix / camry or easily enough to many other toyotas. how is the weight of a chart-car based swap worked out, or is it not allowed?
I'd assume it has to do with forced induction: The A4 uses the 1.8 turbo and the MC-S has a belt driven supercharger. I'm suprised that they don't specify a minimum belt pulley size for the MC-S, as the smaller pulley is an option you get with the John Cooper Special dealer installed package.
