Technical Notes

Turbine housings are critical for directing exhaust gases to the turbine wheel. Ensure the housing flange and inlet/outlet dimensions match your existing turbocharger assembly. Check for any specific mounting bolt patterns or gasket requirements associated with the TO4B91 model. If your turbocharger uses a variable geometry (VNT) system, confirm that the housing design matches your specific unit's requirements, as VNT housings differ from fixed-geometry designs.
