Turbo Guides

Understanding Stage 1 vs Stage 2 Turbocharger Upgrades for Diesel Trucks is the difference between spending money that actually returns power and reliability, and throwing parts at a truck that ends up hotter, laggier, and no faster than stock. At PT Turbo, we have been building and rebuilding turbos since 1978, and over 45 years

Garrett Motion Turbochargers power more diesel engines on the road today than almost any other brand, and the company behind them has one of the longest track records in forced induction. If you’ve turned a wrench on a modern medium- or heavy-duty diesel, you’ve handled Garrett hardware, whether you knew it or not. Understanding where

Welcome to the PT Turbo Generator Turbocharger Guide, a technical breakdown built for the electricians, plant managers, and diesel technicians who keep standby and prime power systems running. Generator sets live a very different life than a truck or a piece of construction equipment. Understanding how that duty cycle affects your turbocharger is the difference

This School Bus Turbocharger Guide covers the two workhorse engines that move most of North America’s yellow fleet: the International DT466 and the Cummins B-Series (5.9L and 6.7L ISB). If you run, maintain, or repair school buses, you already know these engines are built to log a million miles, but the turbocharger bolted to the

A well-run Fleet Diesel Turbocharger Maintenance Program is the difference between a truck that logs 500,000 miles on its original turbo and one that grenades a compressor wheel at 180,000 and takes the engine with it. For commercial operations running dozens or hundreds of units, the turbocharger is one of the most expensive and most

This Construction Equipment Turbocharger Guide covers the three brands that dominate job sites across North America: Caterpillar, Komatsu, and John Deere. Whether you’re running an excavator, wheel loader, dozer, or backhoe, the turbocharger is the single most stressed component on your diesel, and knowing exactly what’s bolted to your engine saves downtime and money. PT

This Marine Diesel Turbocharger Guide covers the three engine families that dominate recreational and commercial waters: Volvo Penta, Yanmar, and Cummins. If you run boats, work barges, or maintain a fleet of commercial vessels, you already know a marine turbo lives a harder life than any on-road unit. Saltwater, constant high load, and limited cooling

Understanding the relationship between Exhaust Back Pressure and Turbocharger Performance is one of the most overlooked skills in diesel diagnostics, yet it separates a technician who guesses from one who actually fixes the problem the first time. Back pressure isn’t inherently bad. In fact, a turbocharger depends on a controlled amount of it to spin

Understanding Turbocharger Sizing Basics is the difference between building a diesel engine that pulls hard from idle and one that either chokes at low RPM or runs out of breath up top. Every turbo is a compromise, and engineers spend a lot of time balancing spool-up, airflow, and backpressure to land in the sweet spot
