In 2004 Porsche released the 911 Turbo S (996) (996TT) with improved the power and brakes over the standard model. The biggest change from the standard 996TT and the 911 Turbo S models was the improved power from 420hp to 450hp. Porsche also upgraded the brake discs to a ceramic version, which they claimed could last up to 150,000 miles. The new Porsche 996 Turbo S achieved the increase in power over the standard by increasing the turbos size and improving the intercoolers while controlling it with a new engine management system. The styling remained relatively unchanged. The 2004 and 2005 Porsche 911 Turbo S were basically a base 996TT with the optional X-50 upgrade (X-50 upgrade came with the same Turbo S engine upgrades) with improved brakes to handle the increased power.
