Dual VVT allows internal EGR but not LIVC. External EGR allows intake timing to be retarded while diluting the charge for very high efficiency down to the 50% load range.

You don't need EGR to pass emissions, 3 way cats do their job very well. EGR just makes it a little easier by reducing NOx production.

Also the S2000 is definitely not .33, it's got a tall windshield and short tail like a Miata, it's probably like .37.
