Top 10 Turbo Mods for the 7.3 Powerstroke
Feb 7th 2026
“Turbo mods” on a 7.3 Powerstroke aren’t limited to the turbocharger itself. Many turbo-related symptoms—slow spool, inconsistent boost, smoke, or elevated EGT—are caused by issues in the supporting system: charge-air boots and clamps, plenums, up-pipes, and turbo pedestal sealing points.
So lets talk the top ten most common turbo modifications for the 7.3 Powerstroke. Here we’ll dive into the top ranked and purchased items by 7.3 owners. No bias, just parts ranked by the people who use them every day.
1. Complete CAC Intercooler Boot Kit (99–03)
The problem: stock boots get oil-soaked, flimsy, and start leaking/blowing off, which turns your boost into “warm thoughts.” This kit replaces the full set with 4-ply aramid-reinforced silicone boots rated for high temp and pressure so the charge-air system stays sealed.
2. Riffraff Diesel Billet Compressor Wheel (94–03)
The problem: the stock wheel (and many “anti-surge-only” wheels) can feel lazy, surge-prone, and leave airflow on the table. This billet wheel targets faster spool + more CFM/boost (Riffraff notes typical boost gains) to improve response and drivability.
3. Riffraff Diesel Plenum Reinforcing Inserts (99.5–03)
The problem: factory plenums can get bent/crushed and won’t seal well—especially when you try to “tighten harder” with better clamps. These inserts stiffen and re-round the plenum so you can clamp down with T-bolts without boost leaks (and without turning the plenum into a Pringle).
4. Non-EBPV / Blank Pedestal (99.5–03)
The problem: the EBPV actuator rod can leak, and the whole EBPV setup becomes one more failure/leak point as these trucks age. A non-EBPV pedestal eliminates the EBPV hardware for a simpler drop-in solution (and plays nice with common turbo upgrades).
5. Turbo / Pedestal O-Rings (94–03)
The problem: classic pedestal oil leaks that make your valley look like an Exxon reenactment. Fresh Viton o-rings reseal the pedestal interfaces and stop the seepage—cheap part, big sanity upgrade.
6. Intercooler Boot Complete Clamp Kit (99–03)
The problem: even great boots can leak if the clamps are weak, mismatched, or you’re still running tired worm-drives that won’t hold boost consistently. This kit gives you properly sized clamps for the common boot locations, and we recomend using plenum inserts to avoid crushing when stepping up to T-bolts.
7. Garrett GTP38R PowerMax Ball Bearing Turbo
The problem: a worn factory turbo can bring slow spool, low boost, smoke, shaft play, and inconsistent power. A new ball-bearing replacement turbo is the “reset button” — restores efficiency and response so the rest of your mods aren’t trying to compensate for a tired charger.
8. Turbo Re-Install Kit (99–03)
The problem: pulling the turbo (or swapping a comp wheel) and reusing old hardware/seals is how you earn mystery leaks and loose bolts later. This kit is meant to be used any time the turbo comes off and includes proper hardware (Riffraff notes OE-style flange bolts and why that matters).
9. Bellowed Stainless Up-Pipe Kit (99.5–03)
The problem: leaking up-pipes = lost drive pressure to the turbine, slower spool, higher EGTs, and the “why does it feel like a 7.3 with asthma?” experience. Bellowed up-pipes are built to stay sealed through heat cycles and movement so the turbo actually gets the exhaust energy it’s owed.
10. Plenum CAC Boot Kit (99.5–03)
The problem: the plenum boots are another common boost-leak point, often aging out after years of heat and oil mist. This replaces both plenum boots on late ’99–’03 trucks running stock intake components, tightening up the system so boost doesn’t escape right before the engine.
