Technical Notes
The GT45 turbocharger is a fixed-geometry unit, so this compressor wheel operates without variable turbine vanes. When assembling a CHRA, ensure the compressor wheel is balanced with the turbine wheel and shaft assembly to prevent vibration. Buyers should verify the flange type and bolt pattern on the existing turbine housing to confirm alignment.
