2004 Cobra Convertible. White, 2000 miles. One owner, flawless as new condition. Debuting in early 2002, the 2003 Cobra (code-named Terminator by the SVT development crew, and quickly fell into common usage for the 2003/04 Cobra), came with a supercharged 4.6 L DOHC engine. Numerous improvements were made to the powertrain and driveline to handle the increase from the previous model year. A cast-iron block was used instead of aluminum, with stronger internals, including forged Zolner pistons and Manley H-beam connecting rods that were modified with a wrist pin oiling hole by the SVT engine builders. These upgrades were critical in order to support the 8 psi (0.55 bar) of boost delivered from the stock Eaton M112 roots supercharger. Other improvements include the use of an aluminum flywheel connected to a Tremec T-56 six-speed transmission, 3.55:1 rear axle ratio and stronger 31 spline half shafts with revised upper and lower control arms. These modifications launched the Cobra from 0-60 mph in 4.5 seconds and the quarter mile in the high 12's at over 110 mph (180 km/h). Some have gone as low as 12.4 seconds with a professional driver and good conditions in stock form.
