Frequently Asked Questions

How do I confirm this BorgWarner part matches my turbo system?
Match the exact BorgWarner part number, turbo family, compressor and turbine wheel sizes, housing A/R, flange, inlet and outlet geometry, bearing housing, wastegate configuration, and every connection before ordering.

Is this BorgWarner SuperCore assembly a direct replacement?
Only when the exact part number, dimensions, housings, flanges, rotation, wastegate configuration, oil and coolant connections, and vehicle or system application all match. Similar turbo families are not automatically interchangeable.

What supporting parts should be inspected during installation?
Inspect or replace the oil feed and drain, coolant lines, gaskets, fasteners, intake and charge piping, intercooler, exhaust connections, wastegate hardware, and filtration components. Correct the cause of the previous turbo failure before startup.
