Cummins ISX15 Turbo & Exhaust Manifold Replacement Package | HE451VE 70mm | Replaces 2882112 | 2010-2016
The Diesel Power Source® HE451VE Turbo & Manifold Package combines a brand-new HE451VE VGT turbocharger with a 70mm compressor wheel, the DPS high-flow ISX15 exhaust manifold, and the exhaust manifold hardware and gaskets into one kit for 2010 to mid/late 2016 Cummins ISX15 engines on the CM2250 and early CM2350 platforms. This package replaces OEM turbo part number 2882112 (and related numbers 3796351, 5456845, 2882110, 2882111). It is built for trucks that need both a turbo and a manifold in the same job, whether from a failed VGT turbo, a cracked exhaust manifold, or both.
On the ISX15, turbo failure and manifold cracking tend to show up in the same mileage window. Replacing only one leaves the other waiting to fail. Doing both at once fixes two of the most common ISX15 failure points in one teardown, saves shop labor, and pairs a fresh turbo with a manifold that flows correctly from day one.
Bundle and save. Buying the turbo and manifold together costs less than buying each one separately, and it puts both jobs into a single install. Choose the EGR manifold for emissions-intact trucks or the Non-EGR manifold for deleted trucks. If you only need the turbo, see our standalone HE451VE turbo (2882112 replacement). If you only need the manifold, see our ISX15 EGR exhaust manifold or ISX15 Non-EGR exhaust manifold.
Important: This kit does NOT fit HE400VG applications. Mid/late 2016-2025 ISX15 and X15 trucks use the HE400VG (OEM PN 5459710), which has a different compressor cover and actuator setup. If your current turbo is an HE400VG, see our HE400VG turbo and manifold package.
Why Replace the Turbo and Manifold Together
A cracked or warped manifold leaks exhaust. That starves the turbo of drive pressure and raises EGTs. A worn turbo with sticking VGT vanes or a failing actuator creates backpressure spikes that crack manifolds faster. Both jobs remove the same parts, so replacing them together is the better use of shop time and money.
The DPS high-flow ISX15 manifold increases exhaust flow approximately 22%, lowers EGTs by approximately 75-100°F, and brings the turbo in roughly 200 RPM sooner under load. The new HE451VE restores proper VGT function and stabilizes backpressure, which also protects the new manifold. Its 70mm compressor wheel is about 2mm larger than the factory 67mm wheel, so it moves more air while keeping the factory fitment, wiring, and engine brake.
What's Included in This Package

Manifold Selection Guide
| Option | Emissions / EGR Configuration | Coating | Best For |
|---|---|---|---|
| Non-EGR, 1,000° coating | Without emissions (deleted / Non-EGR) | Standard ceramic | Deleted trucks, cost-effective option |
| Non-EGR, 1,800° coating | Without emissions (deleted / Non-EGR) | High-temp Cerakote | Deleted trucks, maximum heat protection |
| EGR, 1,000° coating | With emissions (EGR intact) | Standard ceramic | Emissions-intact trucks, cost-effective |
| EGR, 1,800° coating | With emissions (EGR intact) | High-temp Cerakote | Emissions-intact trucks, maximum heat protection |
Choose the 1,800° Cerakote coating for sustained high-load work such as heavy hauling, mountain grades, or hot climates. The 1,000° standard ceramic coating covers standard commercial duty cycles.
Turbo Specifications
| Turbo | Compressor | HP Range | Recommended Use |
|---|---|---|---|
| HE451VE (70mm) - DPS | 70mm inducer, 7-blade FMW | 525-675 HP | Stock replacement with more airflow, heavy hauling, lower EGTs vs. the stock 67mm |
Automatic transmissions: do not use this 70mm turbo on automatic trucks rated below 525 HP.
ISX15 VGT Fault Codes That Lead to Turbo Replacement
VGT actuator codes on the ISX15 are often misdiagnosed as actuator-only failures. Often the real cause is a worn or sticking turbo (OEM PN 2882112) overloading the actuator. If your engine shows any of the codes below, check the turbo and actuator together and replace them together for the most reliable repair.
| Engine / ECM | Cummins Code | SPN / FMI | Meaning |
|---|---|---|---|
| ISX15 CM2250 | 2449 | 641 / 13 | VGT Actuator Controller - Out of Calibration |
| ISX15 CM2250 | 2387 | 641 / 7 | VGT Actuator Driver Circuit (motor) - Not Responding |
| ISX15 CM2350 | 1894 | 641 / 9 | VGT Actuator Driver Circuit - Abnormal Update Rate |
| ISX15 CM2350 | 2198 | 641 / 11 | VGT Actuator Driver Circuit - Root Cause Not Known |
Code 2449 (SPN 641 / FMI 13) is the most common VGT code on CM2250 engines. See the full troubleshooting guide: ISX15 / X15 Turbo Actuator Codes - What They Mean and When to Replace
Common ISX15 Failures This Kit Solves
- Cracked or warped exhaust manifold causing exhaust leaks, smoke at the manifold, and reduced turbo efficiency
- Failed HE451VE turbo (2882112) or actuator causing low boost, turbo position faults, or black smoke
- VGT fault codes - SPN 641 (codes 2449, 2387, 1894, 2198) indicating actuator or turbo failure
- Laggy turbo response from worn turbo bearings or sticking VGT vanes
- Leaking manifold joints from thermal cycling and worn OEM gaskets
- Repeated turbo failures caused by a cracked manifold starving the turbo of exhaust drive pressure
About the Manifold Joint Seal
Every DPS multi-piece manifold uses a hard, metal-to-metal press-fit seal at each joint, with no gasket. The seal tightens as the parts heat and expand, and it seals best at driving temperatures (750°F and higher). A small amount of leakage at cold start or idle can be acceptable on a joint-style manifold.
Every manifold is pressure-tested leak-free at room temperature before it leaves our facility. For a full explanation of how the seal works and why a soapy-water test at idle is not a valid diagnostic, see:

Fitment
This kit fits 2010 to mid/late 2016 Cummins ISX15 engines on the CM2250 (EPA10) and early CM2350 (EPA13) platforms that came with the HE451VE turbo. Compatible with Freightliner, Peterbilt, Kenworth, Volvo, International, and Western Star trucks. Jake brake / engine brake function is fully preserved. After installation, re-torque all manifold and turbo bolts after the first 100 miles at operating temperature.
Select your manifold configuration at checkout: EGR (emissions intact) or Non-EGR (deleted). Select your coating level: 1,000° or 1,800°.
2016 is a split year. Both HE451VE and HE400VG trucks were built in 2016, so model year alone is not enough. Confirm two things before ordering: your engine serial number (ESN), and the part number on your current turbo's tag. A tag reading 2882112 or 3796351 (or a related number in that family) is an HE451VE, and this kit is the right one. A tag reading 5459710 is an HE400VG.
Not for CM871 engines. Approximately 2008-2010 CM871 ISX15 engines used the larger HE561VE turbo, not the HE451VE.
Fitment Verification Required: An HE451VE has BOTH of the following: (1) an elongated compressor cover, and (2) an actuator with two coolant ports. If your turbo does not have both, it is likely an HE400VG and this kit will not fit. See the fitment verification image in the product gallery. ESN verification is required before shipment. Call 801-930-8404 or email sales@dieselpowersource.com and our team will confirm the correct turbo for your engine.
