CAT C15 ACERT Ball Bearing Low Pressure Turbo

BXS / MXS / NXS | 88MM Upgrade | Factory Location

Upgrade the factory low-pressure turbo on your CAT C15 ACERT with modern Garrett ball bearing technology while retaining the factory compound turbo configuration.

The factory BXS, MXS, and NXS C15 ACERT engines use journal bearing high- and low-pressure turbochargers. While the factory compound system is proven, the stock low-pressure turbo can become a limitation when you're looking for improved response and additional airflow from the factory-style compound setup.

The Momentum Worx 88MM Ball Bearing Low Pressure Turbo Upgrade takes the proven Garrett GTA5518BR ball bearing CHRA used on later SDP applications and adapts it to OEM-style ACERT compressor and turbine housings.

The result is a high-performance, factory-location upgrade designed to deliver improved transient response, increased top-end airflow, and stronger high-RPM performance without requiring a complete single-turbo conversion.

Factory Turbo vs. Momentum Worx Ball Bearing Upgrade

Unlike an upgrade that simply increases compressor wheel diameter, the major changes here are the 10-blade high blade count compressor wheel and Garrett ball bearing center section.

Compared with the factory 6+6 compressor wheel, the high blade count design is intended to provide improved top-end airflow, while the ball bearing CHRA reduces friction and improves transient response.

The result is a more responsive, higher-flowing low-pressure turbo while retaining the factory-style ACERT compound system.

Factory-Location Installation

This turbo uses OEM-style compressor and turbine housings and is designed to install in the factory low-pressure turbo location on BXS, MXS, and NXS CAT C15 ACERT engines.

That means you can upgrade the low-pressure side of the factory compound system without custom turbo mounting.

For the high-pressure turbo installation, we also offer our Braided Oil Feed Line for CAT C15 ACERT Ball Bearing High Pressure Turbo Upgrade. The factory high-pressure oil feed line can be reused, but our braided line provides improved clearance around the heat sink fins on the Garrett ball bearing cartridge for a cleaner installation:

Together, the high- and low-pressure ball bearing upgrades improve the performance potential of the entire ACERT compound turbo system while retaining the factory-style configuration.

Who Is This Turbo For?

This upgrade is built for C15 ACERT owners who want more out of the factory compound turbo system.

It's an excellent choice for builds looking for:

• Improved response from the low-pressure turbo
• Increased top-end airflow
• High blade count compressor wheel technology
• A genuine Garrett ball bearing center section
• Factory-location installation
• Improved compound turbo performance without converting to a single turbo

If you're looking to push your BXS, MXS, or NXS C15 ACERT beyond the limitations of the factory low-pressure turbo while keeping the compound setup, this is the upgrade built to do it.
