BD's Turbo Thruster II for the Ford 1994-1997 TP38 and 1999.5-2003 GTP38 7.3L Power Strokes provides a 40% increase in airflow over the stock turbo design with no compressor surging or choked-off turbine flow. The Turbo Thruster II features a HIP'ed (Hot Isostatic Pressed) compressor wheel with 66mm inducer and 70mm exducer that can handle high wheel speeds and boost pressures. The new compressor housing and back plate casting improves turbo spool up time and allows full housing rotation for easier installation. The large 1.0 A/R turbine housing handles higher exhaust flow and eliminates the â??chokeâ?Ł condition experienced with some turbos with .84 housings. The cartridge (or rotating assembly) uses journal bearings and a new 360-degree bronze thrust washer for extended bearing life and making future servicing easier.Designed as a direct, bolt-in replacement for the stock turbo, the Turbo Thruster II has superior pressure ratios, provides cooler EGTâ??s, no compressor surging and capable of developing up to 36psi of boost pressure with BDâ??s exclusive Heavy Duty Waste Gate with Turn Buckle adjustment (1999.5-2003 only). The perfect match for stock or modified engines!
