 the E-shaft RPM is 3 times faster than the rotor RPM.
 
 so it would be equal with 4 cylinder.

I'm not sure it matters how many cylinders it equals.  I think the bottom 
line is power production and fuel consumption.  If it produces power like a 4 
litre and consumes fuel like a 4 litre, it's a lot more like a 4 litre than 
it is like a 1.3 litre.  I think a NA 13B is a lot more like a big 6 than it 
is a 1.3 litre 4.  And a twin turbo 13B produces power a lot closer to 
something between 5.0 and 5.7 litres.  I just think saying "it's a 1.3 litre" 
is naive...
