The AAN and the ABY are the similar in the aspects of the head and block. This includes all the internals within these two components like the crank, pistons, cams, etc. The differences come in the way of intakes, how the accesories mount to the engine, the valve covers are different to accommodate different turbo/intake plumbing, the crankcase ventilation is different, the crank pullies are different and therefore the timing belts are different, the power steering pump and A/C compressor in the ABY is driven via a v-belt (AAN uses a serp belt), the water pumps are different, the fuel rails are different, Oil pans are different, etc. Whue!!!
Besides that the ABY and AAN are the same. :-)
