S7 and RS7 engine differences

[EriCal]

What are the internal differences between a S7 and RS7 engines? I know the turbos are different but what about the internals?

What do you think it is that adds the 11 lbs to the weight of the RS7 motor?
Different steel density? The extra (aux) oil cooler, extra HX? Or are those things not included in the engine weight?
Or is that just a paste from the S8 stats where it has two airboxes and filters and power steering pump and the RS7 motor actually weighs the same as the others?

Unknown.....but note the RS7/S8 block is different since the block is heat treated and has larger main bearings. There may be other structural differences in the block. Maybe they are counting the double air intake and added engine oil/water cooler weight.
