When its time for a new turbo for your early 1999 SuperDuty, why not upgrade it while you're at it? This is a completely re-manufactured unit from Industrial Injection that features an upgraded 7-blade billet anti-surge compressor wheel for quicker spool up and a 1.00AR turbine housing. This results in more mid range, reduced back-pressure, and minimizes the famous 7.3L “shuttering”. With tuning, this turbo will support up to a 60hp injector making it perfect for daily driving or towing.
