I am quite certain that the 91's sold for $61,000, not $81,000.

Can anyone tell me if this is a true statement?
The 1991 Acura NSX features VVIS (Variable-Volume Intake System) which is a magnesium plenum below the intake chamber which opens 6 butterfly valves above 4800 rpm- This allows for a larger air passage to the engine at higher rpm's.
The '91 NSX also features VTEC (Variable Valve Timing and Lift Electronic Control). A normal cam lobe is accompanied by a second and more aggressive cam lobe that turns on at around 5800 rpm that keeps the valves open wider and longer.
I knew about VTEC, but VVIS???
Nothing against this seller, just wondering.
