Expert turbocharger rebuilds for fleets and owner-operators. Holset, BorgWarner, Garrett, Detroit, IHI, Cummins — all major diesel platforms. Net 30 terms. 24-hour target turnaround. Every rebuild VSR-balanced and QC-tested.
From full teardown to final balance — every turbo gets the same thorough inspection, precision rebuild, and quality control process.
Full teardown and inspection of every component. We photograph the damage, document findings, and provide a detailed quote before any work begins. $50 flat inspection fee.
Complete rebuild with OEM-spec parts. New seals, bearings, thrust components, and hardware. CHRA overhaul or replacement available. VGT vane and unison ring service included on variable geometry models.
Every rebuilt turbo is VSR balanced at operating RPM and put through QC before shipping. Balancing is the single most important step — unbalanced wheels destroy bearings and fail catastrophically. We verify endplay, radial clearance, and boost response to OEM tolerances.
Send us your core, we rebuild it. Or purchase a remanufactured unit outright with core deposit. Either way, you get a fully rebuilt turbo with our standard warranty.
Variable geometry turbo giving you trouble? We service VGT vanes, unison rings, and nozzle ring assemblies. Full cleaning, inspection, and rebuild of the variable geometry mechanism.
Rebuild kits, CHRAs, cartridges, and individual components available for purchase. We source from trusted OEM and aftermarket suppliers. Available on eBay and Amazon.
We specialize in heavy-duty diesel turbochargers across all major OEM platforms.

Running a fleet? We built our process around operators who need turbos rebuilt fast, priced right, and with minimal paperwork.
A rebuilt HE400VG or HE351VE on a work truck can cost less than half of new — but only if it's rebuilt with OEM-grade parts, balanced at operating RPM, and QC-tested. We break down what a proper truck turbo rebuild actually looks like and where most shops cut corners.
Turbo wheels spin at 100,000+ RPM. Even a tiny balance defect translates into massive bearing load and catastrophic failure — often grenading the engine it's bolted to. We explain why high-speed VSR balancing isn't optional and why most garage-floor rebuilds end up shortening the life of the turbo they were supposed to save.
Restoring heavy-duty diesel turbos — HE400VG, HE451VE, S400, GTA — to OEM precision. What a proper VGT rebuild looks like, why balancing matters on class 8 trucks more than anywhere else, and how fleet shops can cut their turbo spend without cutting life.
Turbo Doctor is a turbocharger rebuild shop serving fleets, independent shops, and owner-operators across the United States. We specialize in heavy-duty diesel turbochargers — Holset, BorgWarner, Garrett, Detroit, IHI, Cummins — and we built our operation around one idea: get the turbo rebuilt right, get it back fast, and make the paperwork painless.
Every turbo we rebuild goes through a full inspection, precision rebuild with OEM-spec components, high-speed VSR balancing, and quality control testing. We don't cut corners and we don't ship anything we wouldn't put on our own trucks.
For fleet customers, we offer contract pricing, stocked inventory of the models you run, Net 30 terms, and a digital work order system that eliminates the back-and-forth. Ship us your core, approve the work order online, and we handle the rest — including sending the invoice directly to your AP department when the rebuilt turbo ships.
