HE351VE vs HE300VG: 6.7L Cummins Turbo Differences
Cummins used two different variable-geometry turbos across the 6.7L era, and owners often mix them up. Knowing which one you have matters for parts, diagnosis, and upgrades.
Quick answer: The HE351VE is the factory VGT on 2007.5–2012 6.7L Cummins trucks; the HE300VG replaced it on 2013–2018 trucks. Both are variable-geometry turbos with exhaust braking, but they differ in design and calibration. True North Turbos builds an HE300VG-style drop-in that fits the full 2007.5–2018 range.
By model year
- 2007.5–2012 6.7L Cummins: HE351VE
- 2013–2018 6.7L Cummins: HE300VG

What's the same
Both are Holset variable-geometry turbos: movable turbine vanes, an electronic actuator, quick spool, and factory exhaust braking. Both are also prone to the same real-world issues — vane sticking and actuator faults — as they age.
What's different
The two turbos differ in internal design, sizing, and actuator calibration, so parts and tuning aren't universally interchangeable between them. If you're buying a replacement or upgrade, match it to your year rather than assuming cross-compatibility.
The upgrade path for both
Rather than sourcing separate turbos, True North Turbos offers an HE300VG 63mm drop-in engineered to fit 2007.5–2018 6.7L Cummins trucks — so owners of both the HE351VE-era and HE300VG-era trucks can move to one upgraded, VGT-style unit that keeps the exhaust brake. See Best HE300VG Drop-In Turbo Upgrades for the details.
Frequently asked questions
Which is better, the HE351VE or HE300VG?
Neither is strictly "better" — they were fitted to different model years. Both tow well and both benefit from upgrading when high-mileage or when you want more airflow.
Can I put an HE300VG on a 2007.5–2012 truck?
True North Turbos builds an HE300VG-style drop-in that covers 2007.5–2018. Confirm fitment for your specific truck before ordering.
Do the HE351VE and HE300VG use the same parts?
Not universally — internal design and calibration differ, so match parts to your year.
