Specialist Quality Benchmarks

To maintain your brand’s focus on high-performance reliability, these technical details will justify a premium price point and build buyer trust:

• Turbine Shaft Play: At your level of service, confirming “Zero axial or radial shaft play” is the single most important detail for a turbocharger sale.

• Electronic Wastegate (EWG): Since this is the EWG version, specify that the “Electronic actuator is included and has been cycle-tested for smooth operation.” This saves the buyer from having to calibrate or swap their old actuator.

• Housing Integrity: Mention that the “Exhaust manifold/hot-side housing is free of heat-stress cracks,” particularly around the wastegate flapper seat.

• Impeller Condition: Describe the compressor wheel blades as “Pristine / No leading-edge pitting or ‘dusting’ from poor filtration.”
