Choosing the best Power Stroke turbocharger upgrade comes down to your real power goal and the exact engine you have, because the 7.3L, 6.0L, and 6.7L each use very different turbos. A turbo that is too small runs out of air and makes heat up top, while one that is too large is lazy off the line. Matched correctly, a turbo upgrade wakes a Power Stroke up, lowers exhaust temperatures under load, and gives your fuel the air it needs to make clean power. This guide walks through how to size a Power Stroke turbo, the year fitment you must get right, and our top Garrett and ATS Diesel picks so you buy once and buy correctly.
How to size a Power Stroke turbo
Start from your goal and your typical use, then pick the smallest turbo that meets it. A right-sized turbo spools quicker, tows cooler, and lasts longer than an oversized one chased for a peak number.
- Stock replacement or mild upgrade: a drop-in or a Stage 1 turbo that fits the factory location restores or slightly improves airflow with a clean install, ideal for a daily and tow truck.
- Moderate to high power: a larger single or PowerMax-style turbo feeds a tuned truck with bigger fuel and drops exhaust temps under load.
- Serious builds: a large single or a compound-style setup belongs on trucks with the fuel, tune, and drivetrain to match.
It also helps to know the difference between a drop-in and a full kit. A drop-in turbo reuses your factory mounting and plumbing for a straightforward swap, while a kit includes the manifold, plumbing, or hardware needed for a larger turbo or a new location. Drop-ins keep the job simple, kits open the door to more airflow.
Get the year and engine fitment right
Power Stroke turbos are engine-specific, so match your exact truck before anything else:
- 7.3L Power Stroke (1999.5-2003): its own turbo, not shared with the later engines.
- 6.0L Power Stroke (2003-2007): a variable-geometry turbo unique to that engine.
- 6.7L Power Stroke (2011-2019): its own variable-geometry turbo again, in a different size range.
Confirm the year and engine, then choose the turbo. Fitment matters more than chasing a specific brand.
Our top Power Stroke turbo picks
These Garrett and ATS Diesel turbos cover the common Power Stroke needs from a clean drop-in to a serious build, sorted by platform.
Best for the 7.3L (1999.5-2003)
For the 7.3L, the Garrett GTP38R turbo kit for the 7.3L Power Stroke is a proven ball-bearing upgrade that wakes up the old 7.3 with quicker spool and more top-end air.
Best for the 6.0L (2003-2007)
For the 6.0L, the Garrett PowerMax GT3788VA Stage 1 turbo for the 04-07 6.0L is a strong drop-in variable-geometry upgrade, and there is a matching GT3788VA Stage 1 turbo for the 2003 6.0L for the early trucks.
Best for the 6.7L (2011 and up)
For the 6.7L, the Garrett 63.5mm AVNT3788R PowerMax turbo for the 17-19 6.7L and the 15-16 version are proven PowerMax upgrades, and the ATS Aurora 3000 VFR Stage 2 turbo for the 15-16 6.7L is a strong alternative.

Match the turbo to the rest of the build
A turbo is one part of a system. To use a bigger turbo you need fuel to match, meaning injectors and a pump sized for the airflow, a tune written for the turbo, and healthy exhaust and intake plumbing so it can breathe. A big turbo on stock fuel will be lazy, and big fuel on a small turbo makes heat and smoke. If you are also planning injectors, our guide on the best 6.7L Power Stroke fuel injector upgrades covers sizing, and our 6.0 vs 6.4 vs 6.7 Power Stroke comparison explains the platform differences that shape your turbo choice.
Signs your Power Stroke turbo needs attention
A worn or undersized turbo shows itself in a few ways. Watch for high exhaust gas temperatures under load, especially when towing, a whistle or grinding from the turbo, oil in the intake tract from worn seals, sluggish spool and slow throttle response, and boost that will not hold. On the 6.0L and 6.7L, a variable-geometry turbo that sticks from soot can set boost codes and cause limp mode. If your truck is down on air, running hot up top, or you have added fuel that the stock turbo cannot feed, a properly sized upgrade is usually the fix, and it is the moment to decide how far to step up.
Frequently Asked Questions
What is the best Power Stroke turbo for a daily driver?
For a daily or tow truck, a drop-in or Stage 1 turbo that fits the factory location is usually the best Power Stroke turbocharger upgrade. It restores or slightly improves airflow, lowers exhaust temps, and installs cleanly without major plumbing.
Will a bigger turbo add power by itself?
No. A turbo needs matching fuel and a tune to make its power. A big turbo on stock fuel is lazy, and big fuel on a small turbo makes heat. Balance the turbo, injectors, pump, and tune together.
Do the 7.3, 6.0, and 6.7 Power Stroke use the same turbo?
No. The 7.3L, 6.0L, and 6.7L each use their own turbos in different size ranges, and they are not interchangeable. Confirm your exact year and engine before choosing one.
What supporting parts do I need for a turbo upgrade?
Fuel to match the airflow, meaning injectors and a pump sized for the goal, a tune written for the turbo, and healthy intake and exhaust plumbing. Balance the whole system for clean, reliable power.
Bottom line
The best Power Stroke turbocharger upgrade is the one matched to your power goal and your exact engine. A drop-in or Stage 1 turbo suits a daily, tow, or moderate build, while a larger single or compound-style setup feeds a serious truck. Confirm your 7.3L, 6.0L, or 6.7L fitment first, size the turbo to your fuel and tune, and keep the intake and exhaust healthy, and your Power Stroke makes clean power with cooler exhaust temps under load.
