It would blow a cloud of smoke and smell awful when accelerating full throttle last VTEC. Ours never needed emissions work, but it is very possible that the previous owner did some trickery.

I also noticed that the S2000 was about as slow as my I4 accord up to 6000 RPM, then they switched roles as the S2000 screams ahead and the accord lags behind.
VVT engines improve the emissions output (WAY less) 100% of all VVT engines have no EGRs.. 50% less no EGR required that is why most of the are LEV2 or SULEV etc.. mine with VVT has LEV2 rating while a non VVT has a LEV rating
