OBS 7.3 BD Diesel Thruster 2 Turbo Upgrade 1994-1997
Turbo Thruster II features a HIP'ed (Hot Isostatic Pressed) compressor wheel with 66mm inducer and 88mm 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 “choke” 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 EGT’s, no compressor surging and capable of developing up to 36 psi of boost pressure. This turbocharger is non-wastegated.
