There is a replacment for Displacment and its called a Turbo, and its what makes V8 Eaters out of 4 bangers... and 6 cylinders in the case of my Supra 

If you put a turbo on a 4 banger and a turbo on a V8, which do you think has the greater potential?
Why compare forced induction 4 bangers against N/A V8's...Don't you think it best to compare forced induction against forced induction and N/A against N/A...
So it looks like you are mistaken on this as There is
NO replacment for Displacment
