Without a doubt the Ferrari Enzo is one of the most exclusive and rare cars available on the tuning market with a 6.0-liter 12 cylinder mid-engine berlinetta. Dubbed the Enzo XX Evolution, Edo Competition took it to the next level by increasing the performance with several aftermarket parts. They were able to increase the displacement from 6.0 to 6.3-liters, added new camshafts, connecting rods, titanium valve spring retainers, and then modified the cylinder heads for the displacement increase. High performance exhaust headers were installed, along with high flow catalytic converters and a muffler. The stock hydraulic tappets on the Ferrari Enzo were replaced with solid tappets that allow the 12 cylinder Enzo XX Evolution to rev a remarkable 9,600 rpm. Edo Competition was able to boost the Ferrari Enzo to 840 horsepower, while making the vehicle 100 kilograms (220 lbs) lighter.
