Engine Specifications & Applications of the Detroit Diesel 8V92 Engine

(Turbocharged and Naturally Aspirated Versions)

Overview: Detroit Diesel 8V92 Series

The Detroit Diesel 8V92 is a V8, two-stroke diesel engine from the powerful 92 Series—engineered to deliver high torque and dependable power across marine, industrial, and military platforms. With eight cylinders and a total displacement of 736 cubic inches (12.05 liters), this engine has been a staple in heavy-duty applications for decades.

Produced in both turbocharged and naturally aspirated (non-turbo) versions, the 8V92 delivers performance flexibility depending on the demands of the equipment. Both configurations rely on a Roots-style blower for air scavenging, but the turbocharged version adds a turbocharger to increase airflow and power output.

Diesel Pro Power carries a full line of aftermarket parts for both the turbo and non-turbo 8V92 engines, including blower kits, turbochargers, cylinder heads, gasket sets, and more.
