HE400VG Turbo for Cummins ISX15 / X15 | Direct Replacement VGT | 2016–2024
The Diesel Power Source® HE400VG is a direct replacement VGT turbocharger for 2016–2024 Cummins ISX15 and X15 engines. This turbo replaces the factory Holset HE400VG with an upgraded design that uses forged machined compressor wheels (FMW), improved engineering to address known OEM weak points, and a brand-new electronic actuator (not remanufactured). Choose between the standard 67mm compressor (HE467VG) or the DPS-exclusive 70mm compressor (HE470VG) for applications above 500 HP.
Every DPS HE400VG turbo ships with no core charge, a new intake air temperature sensor, new gaskets, and installation hardware. ESN verification is required before shipment to confirm correct fitment for your engine configuration.
Important: This turbo does NOT fit HE451VE applications. The HE451VE uses a different compressor cover and actuator configuration that is not compatible with this turbocharger. If your current turbo is an HE451VE, contact us before ordering so we can confirm the correct replacement for your engine.
Compressor Size Options: 67mm vs 70mm
| Turbo Option | Compressor | Max HP | Recommended Use |
|---|---|---|---|
| HE467VG (67mm) | 67mm inducer, 7-blade FMW | ~575 HP | Stock replacement, mild tuning, daily work trucks, fleet applications |
| HE470VG (70mm) | 70mm inducer, 7-blade FMW | ~700 HP | Builds over 500 HP, performance tuning, heavy hauling with increased fueling |
The 67mm compressor is the largest size that comes on the factory Holset turbo. The 70mm compressor is exclusive to Diesel Power Source® and is not available from OEM or other aftermarket suppliers. Both options use the same 11-blade turbine wheel (72mm inducer, 68mm exducer) and share the same VGT housing and actuator.
Why Replace Both the Turbo and Actuator Together
Diesel Power Source® strongly recommends replacing the turbo and actuator as a pair. Installing a new turbo with an old actuator (or a new actuator with a worn turbo) can cause VGT calibration errors, reduced performance, and premature component failure. Each DPS HE400VG turbo ships with a brand-new, pre-calibrated electronic actuator specifically matched to the turbo for proper VGT control from the first startup.

Cummins X15 HE400VG Turbo Replacement Guide
The Holset HE400VG is the factory variable geometry turbocharger used on many Cummins X15 and ISX15 engines built between 2016 and 2024. Over time, these turbos can wear due to heat cycling, electronic actuator failure, soot buildup in the VGT vanes, or bearing deterioration. When replacing a Cummins X15 turbo, it is important to choose a replacement that maintains full OEM VGT function while addressing the known durability issues found in the factory design.
The Diesel Power Source® HE400VG is engineered as a direct bolt-on replacement with performance-minded upgrades including forged machined compressor wheels for improved airflow and durability, and a DPS-exclusive 70mm compressor option for builds exceeding 500 HP.
OEM Part Numbers Replaced
This Diesel Power Source® HE400VG turbocharger replaces the following Holset and aftermarket part numbers used on Cummins ISX15 and X15 engines:
| OEM / Aftermarket Part Number | Notes |
|---|---|
| Holset 2882112 | Common HE400VG application |
| Holset 3796351 | HE400VG variant |
| Holset 5459710 | HE400VG for CM2350 platforms |
| Holset 5358001 | HE400VG variant |
| Holset 5358454 | HE400VG variant |
| Holset 5458936 | HE400VG variant |

Fitment varies by engine configuration. Always verify compatibility using your Cummins ESN before ordering. Diesel Power Source® will confirm fitment before shipment.
Cummins X15 Turbo and VGT Problems (Common Symptoms)
If you are experiencing any of the following, your factory HE400VG turbo or VGT actuator may be failing:
- Low boost or underboost under load, especially on grades
- Slow spool or laggy turbo response compared to normal operation
- Excessive black smoke during acceleration or under load
- VGT actuator fault codes or turbo position sensor errors
- Whining, scraping, or unusual noise from the turbo
- Repeated boost-related check engine light events
- Increased EGTs at the same load and speed compared to previous readings
Because VGT actuator failures can mimic turbo failure (and vice versa), this turbo includes a brand-new electronic actuator to reduce the risk of repeat repairs. If you are replacing due to actuator-related fault codes, replacing both the turbo and actuator together is the most reliable repair path.
Fitment Verification Required: If your current turbo has BOTH of the following, this HE400VG turbo will NOT fit your application: (1) an elongated compressor cover, and (2) an actuator with two coolant ports. See the fitment verification image in the product gallery. If you are unsure, submit your ESN and our team will confirm the correct turbo for your engine.
Fitment
This turbo fits Cummins ISX15 and X15 engines with CM2250 (some years) and CM2350 platforms. Engine build date must fall between 2016–2024. ESN verification is required before shipment.
Compatible with Class 8 trucks including Freightliner, Peterbilt, Kenworth, Volvo, International, and Western Star platforms equipped with ISX15 or X15 engines.
Not compatible with HE451VE applications. If your current turbo is an HE451VE, contact Diesel Power Source® before ordering.
Save with the Turbo & Manifold Package
If your exhaust manifold is cracked, warped, or leaking alongside a failing turbo, consider the HE400VG Turbo & Exhaust Manifold Package. This bundle includes this same HE400VG turbo plus the DPS high-flow exhaust manifold and complete hardware kit at a package price. Replacing both at the same time reduces installation time and eliminates two of the most common ISX15 failure points in one job.
Warranty
This Diesel Power Source® HE400VG turbocharger includes a 1-year warranty and is backed by our technical support team.
