The Detroit Diesel 12V92 Turbocharged engine is a high-horsepower, two-stroke diesel V12 engineered for the most demanding commercial, marine, and industrial applications. Built on the proven 92 Series platform, the 12V92 Turbo uses a combination of a Roots-style blower and a turbocharger to increase airflow and deliver exceptional torque, power, and reliability. With a total displacement of 1,104 cubic inches (18.1 liters) and output ratings reaching up to 875 horsepower, the 12V92 Turbo remains a trusted solution for high-load, continuous-duty environments. Diesel Pro Power supports this legacy with a full inventory of aftermarket turbochargers, rebuild kits, gaskets, and more—all built to meet or exceed OEM performance standards. Specification Value Configuration V12, two-stroke diesel Displacement 1,104 cu in (18.1 liters) Bore x Stroke 4.84 in x 5.00 in Aspiration Turbocharged + Roots-style blower Horsepower Output 750–875 HP @ 2,100–2,300 RPM Torque Output 1,750–2,000 lb-ft Cooling System Water-cooled Fuel System Mechanical unit injectors Oil Capacity ~45–50 quarts Dry Weight ~3,900–4,200 lbs (varies by configuration) Valves per Cylinder 4 Air Induction Scavenged through cylinder ports Note: Like all Detroit Diesel 2-cycle engines, the 12V92 uses only exhaust valves. Intake air enters through ports in the cylinder liner, pressurized by the blower and turbocharger for efficient uniflow scavenging. Maximum Power Density: Up to 875 HP from a compact V12 platform High Torque Output: Ideal for heavy propulsion and equipment loads Improved Air-Fuel Burn: Turbocharging enhances fuel efficiency and reduces smoke Excellent Throttle Response: Delivers power immediately under load All-Mechanical Reliability: No electronics, sensors, or ECMs required Tugboats and Towboats Offshore Supply Vessels Commercial Fishing Trawlers Push Boats and River Barges Large Marine Generator Sets The 12V92 Turbo is favored in marine settings for its power-to-size ratio and ability to handle long, high-load duty cycles. High-Capacity Water and Mud Pumps Oilfield Skid-Mounted Power Units Underground Mining Equipment Hydraulic Drilling Systems High-RPM Air Compressors Turbocharged 12V92s are a trusted solution where downtime is not an option and mechanical simplicity is key. Heavy Tactical Vehicles Amphibious Landing Craft Mobile Generator Systems Combat Engineering Equipment The 12V92 Turbo’s torque, repairability, and non-electronic design make it a natural fit for battlefield-ready applications.
