This 78 mm PDI Big Boss turbo supplies pressurized intake air, using energy from the engine’s exhaust to drive its compressor.
This version uses an HSM exhaust housing. Exhaust gas turns the turbine wheel, which drives the compressor wheel on the same shaft. The compressor then forces air into the engine’s charge-air system. The wheel size, housing and mounting connections are the main details to match when choosing this turbo for a replacement or planned engine setup.
