Comp Turbo – OEM Turbocharger Upgrade Program

Comp Turbo Technology Inc. offers industry-leading turbocharger upgrade services for Garrett, BorgWarner and a wide range of OEM manufacturers.
Our upgrade program is designed to significantly increase performance, reliability, and response without requiring customers to switch to a full aftermarket turbocharger.

What’s Included in Our OEM Turbo Upgrade Service

Each upgraded turbocharger receives the following:

Billet Compressor Wheel Upgrade

Factory cast compressor wheels are replaced with our CTR engineered for higher flow, improved efficiency, and faster spool.

Turbine Wheel Upgrade (select models)

Certain OEM units benefit from a lightweight, higher-efficiency turbine wheel to support increased flow and reduce backpressure.

CNC-Machined Compressor Housing

Your compressor housing is CNC-bored in-house to perfectly match the new XHF 2.0 compressor wheel for maximum performance and factory-fit reliability.

Complete Remanufacturing Service

Every upgraded turbo is fully remanufactured to restore factory-new tolerances and durability.

Triplex Ceramic™ Ball Bearing CHRA (optional)

For many OEM turbo models, we offer our patented Triplex Ceramic™ ball bearing CHRA, which delivers 3x thrust load capacity and drastically improved response over factory journal bearings.
