Complete Buying Guide for 6.7 Cummins Turbo Upgrade
Essential Factors We Consider
Verify 2019–2022 Ram 2500/3500 6.7L fitment, exact BD part number, emissions certification for your location and supporting calibration needs with BD and your installer.
Choose Your Path First: Deleted or Emissions-Intact Decides Everything
There is no single “best turbo” for a 6.7 Cummins — there are four paths, and the first filter is whether your truck still has its factory emissions equipment (EGR, DPF, DEF, factory exhaust brake). If it does, only the first two paths are open to you. The swap paths require the factory VGT and emissions hardware to be removed, which is a delete-kit decision with legal consequences in your location — settle that before shopping for a turbo.
| Path | What it is | Power range | Exhaust brake | Best for |
|---|---|---|---|---|
| 1. Drop-in VGT upgrade | A larger, stronger replacement for the factory HE300VG in the stock location | Stock to ~500–650 RWHP | Kept — it is the same VGT design | Daily driving and towing on an emissions-intact truck; the pick reviewed on this page |
| 2. Add-a-turbo compound | A second, larger atmospheric turbo added alongside the factory VGT | Stock to ~700 RWHP | Kept | Heavy towing with emissions intact; biggest EGT drop without deleting |
| 3. 2nd-gen swap | Fixed-geometry turbo on a new manifold, VGT removed | ~500–850+ RWHP | Lost — needs an aftermarket inline brake (e.g. Pacbrake) for downhill control | Deleted trucks chasing simplicity, sound, and high power |
| 4. 3rd-gen swap | Fixed-geometry turbo in the factory location, VGT removed | ~500–1,000 RWHP | Lost unless a VGT-style unit is fitted | Deleted trucks wanting the fastest install and a near-stock engine bay |
Fitment by Generation: This Pick Is 2019–2022 Only
The BD Diesel Screamer reviewed here is listed for 2019–2022 Ram 2500/3500 6.7L only. Most of the search traffic for this topic is for older trucks — 2010, 2013, 2014, 2017, and 2018 models — and this listing does not cover them. Do not order by model name alone: confirm the exact BD part number, your truck’s year and cab/chassis configuration, and local emissions approval with BD Diesel before buying. A turbo that bolts on but is not certified for your truck and location is the wrong turbo.
What Size Turbo for Towing vs. Power
Turbo size is the compressor-wheel inducer diameter. The working rule from diesel specialists: stock replacement is 60–61 mm; a 63–64 mm drop-in is the sweet spot for towing and daily driving because it adds airflow without giving up spool-up or EGT control; 67 mm and up is for high-power builds that already have the fueling, tuning, and transmission to use it. Bigger is not better on a stock-fuel truck — it spools later, tows worse, and runs hotter at low RPM.
Before You Bolt It On: The Fix-First Checklist
A new turbo is easily killed by an old problem. Before installation, check: the oil feed line and oil drain for restriction or coking (a starved bearing fails fast); the exhaust manifold for cracks that will warp the new turbo’s flange; all seals and gaskets; and the VGT actuator — repeat codes P003A, P2262, P00AF, and P0299 are the classic signs the factory VGT is failing, and if you have already replaced it once or twice, a swap path that eliminates the VGT entirely may be the better long-term answer than another drop-in. Budget for installation labor, seals, the oil-feed inspection, and any required calibration — never budget on the turbo listing price alone.
Budget Planning
Plan for installation labor, seals, oil-feed inspection and any required calibration. Do not budget using only the turbo listing price.

Frequently Asked Questions
Q: Is a stock replacement turbo an upgrade?
Usually no. A like-for-like HE300VG replacement restores the original type of hardware.
Q: Does this fit 2013–2018 trucks?
The observed Screamer listing identifies 2019–2022 Ram 2500/3500. Confirm any other application with BD Diesel.
Q: Is tuning required?
Follow BD Diesel installation and application guidance; do not assume a generic tune or emissions modification is appropriate.
Q: What size turbo is best for towing a 6.7 Cummins?
A: A 63–64 mm drop-in VGT. It improves airflow and EGT control without sacrificing the quick spool-up that gets a loaded truck moving or the exhaust brake that holds it back downhill.
Q: How do I know my factory VGT is failing?
A: The repeat trouble codes are P003A, P2262, P00AF, and P0299, often with sluggish boost, poor throttle response, or a stuck exhaust brake. If the VGT has already failed more than once, ask your installer whether eliminating it with a swap kit makes more sense than another drop-in.
