Parts for Detroit Diesel 16V149 Turbo Engines

The 16V149 turbo Detroit Diesel engine is a powerful engine that is designed to handle heavy-duty usage. The way that turbo engines like this work is basically by shoving compressed air through the system to cause it to reach higher horsepower than normal, which gives your engine greater power and speed. However, in order to make sure that your engine reaches its potential horsepower, it is essential to keep it properly serviced and maintained.

As with all engines, you might periodically have to change some of your 16V149 Turbo Detroit Diesel parts. Your parts might become worn, damaged, or broken, causing them to malfunction or not to work at all. Continuing to use a part that isn't working properly can cause you much more trouble the more you use it. Here at Diesel Pro Power, we have all the Detroit Diesel parts that you could possibly need for your engine.

Our selection of 16V149 Turbo Detroit Diesel replacement parts are all specifically designed to work with this model of engine. Placing parts in an engine that aren't designed for it can cause major damage to your engine, either immediately or over time. Although other models might seem to fit in your engine, using them is not recommended because even if the engine seems to function fine, the wrong part could be causing internal damage on the engine that will shorten its life expectancy.

Don’t go without the parts your need for your 16V149 Turbo when we have everything you need to fix or service your engine here. All our orders ship within 24 hours, and we also offer international shipping.


Detroit Diesel 16V149 Turbo Engine Specifications & Applications

Overview of the Detroit Diesel 16V149T and 16V149TA Engines

The Detroit Diesel 16V149T and 16V149TA engines are heavy-duty, high-displacement, turbocharged diesel powerplants from the industry-renowned 149 Series. With 16 cylinders arranged in a 90-degree V configuration, each displacing 149 cubic inches, these engines deliver a massive 2,384 cubic inches (39.1 liters) of total displacement. The addition of turbocharging (T) and aftercooling (TA) enables these engines to produce up to 1,800+ horsepower and over 4,500 lb-ft of torque, making them one of the most powerful mechanically-governed diesel platforms ever manufactured.

Fully mechanical, highly modular, and engineered for continuous high-load operation, the 16V149T/TA continues to power demanding applications in marine propulsion, oilfield services, mining, and large-scale industrial operations—backed by a robust aftermarket ecosystem.

Key Performance Benefits of the 16V149T / TA

The turbocharged 16V149 platform builds on the already massive capability of the 149 Series by delivering dramatically improved combustion efficiency and torque output. The addition of an aftercooler in TA models reduces intake air temperatures, leading to:

  • Greater horsepower at continuous duty

  • Lower exhaust temperatures

  • Improved longevity for pistons, liners, and valves

  • Enhanced fuel efficiency under sustained load

Turbocharging also reduces power loss at higher altitudes and improves throttle response for faster engine ramp-up.


Common Applications of the Detroit Diesel 16V149T / TA Engine

Marine Applications

The turbocharged 16V149 is a marine powerhouse, widely trusted for propulsion and onboard auxiliary power across commercial and government fleets.

Typical Marine Use Cases Include:

  • High-horsepower ocean-going tugboats

  • Fast-response pilot and fireboats

  • Deep-draft dredging vessels

  • Offshore support ships

  • Military landing craft and patrol vessels

Marine Benefits:

  • Higher thrust at lower RPM for better control

  • Aftercooling reduces exhaust temps in enclosed engine rooms

  • Compatible with marine transmission and raw water systems

Diesel Pro Power Supports Marine Engines With:

  • Turbocharger assemblies (including water-cooled models)

  • Marine-specific exhaust manifolds and elbows

  • Raw water pumps, impellers, and cooling system parts

  • Heavy-duty marine motor mounts and vibration dampers

Industrial & Stationary Applications

The 16V149T is also ideal for large-scale, high-output industrial engines that must run around the clock in demanding environments.

Common Land-Based Applications Include:

  • Oilfield frac pump engines

  • Prime and standby diesel generator sets

  • Open-pit mining excavators and trucks

  • Large water transfer and irrigation systems

  • High-horsepower compressors and blowers

Industrial Advantages:

  • Fully mechanical—no ECMs or sensors required

  • Modular design simplifies field rebuilds

  • Ultra-high torque output for startup loads

  • Suited for off-grid environments with limited technical infrastructure
