Parts For Detroit Diesel 12V92 Turbo - Exhaust Section

Parts for Detroit Diesel 12V92 Turbo – Exhaust Section

The Detroit Diesel 12V92 Turbo engine is one of the most recognized and respected members of the legendary two-stroke Detroit Diesel Series 92 family. Known for its high horsepower output, durability, and long-standing use across marine, industrial, and heavy-duty truck applications, the 12V92T is a powerhouse that relies on an efficient exhaust system to maintain performance and temperature control. The exhaust components in this section have been carefully selected and tested to meet or exceed OEM performance standards, ensuring long service life and reliability even under extreme operating conditions.

Whether you’re maintaining a marine propulsion system, rebuilding a heavy-duty truck engine, or performing a complete overhaul of a stationary industrial generator, Diesel Pro Power offers genuine and replacement Detroit Diesel 12V92 Turbo exhaust parts ready to ship worldwide.

Detroit Diesel Exhaust Manifold for 6V92 and 12V92 Turbo – Rebuilt

The Detroit Diesel Exhaust Manifold for 6V92 and 12V92 Turbo engines plays a critical role in channeling exhaust gases efficiently from the cylinder heads toward the turbocharger. This manifold is available fully rebuilt and tested for precise fit and performance, ensuring consistent exhaust flow and optimal temperature distribution.

For the 12V92T configuration, four exhaust manifolds are required, while the smaller 6V92T setup uses two. Both applications benefit from this water-cooled marine-style manifold, which helps maintain lower operating temperatures and prevents premature cracking or warping that can occur with dry-style manifolds.

Each manifold has been meticulously machined, pressure-tested, and prepared with corrosion-resistant coatings ideal for marine or industrial environments. Rebuilt manifolds from Diesel Pro Power offer a cost-effective alternative to new OEM units without compromising reliability or fitment.

Detroit Diesel Bolt, Stud, Washer, and Nut for Exhaust Manifold

The exhaust manifold fasteners—including bolts, studs, washers, and nuts—are critical in securing the manifold to the engine head and maintaining a consistent seal under fluctuating temperatures and vibrations.

• Manifold bolts are manufactured from heat-treated alloy steel designed to resist stretching and loosening under thermal expansion.

• Studs and nuts provide even clamping pressure across the manifold surface, reducing the risk of exhaust leaks.

• Hardened washers are included to prevent galling and maintain torque integrity.

Regular replacement of these components during manifold service or engine overhauls is recommended, as reused hardware may lose clamping strength. Diesel Pro Power supplies factory-spec hardware engineered for Detroit Diesel 6V92, 8V92, 12V92, and 16V92 engines, ensuring precise compatibility and reliability across all Series 92 variants.

Detroit Diesel Head to Manifold Gasket

The head-to-manifold gasket serves as the sealing interface between the exhaust ports of the cylinder head and the exhaust manifold. Constructed from reinforced composite materials and metallic layers, it is designed to withstand extreme temperatures and pressures.

For 6V71 and 6V92 engines, this gasket prevents exhaust gas leakage, which can lead to power loss, reduced turbocharger efficiency, and higher engine temperatures. Replacing gaskets during any manifold service is essential for maintaining a leak-free system and ensuring consistent performance. Diesel Pro Power provides these gaskets individually, allowing for complete maintenance flexibility whether you are servicing one bank or performing a full system overhaul.

Detroit Diesel Turbo Riser Adaptor

The Detroit Diesel turbo riser adaptor connects the exhaust manifold to the turbocharger assembly, providing the correct height and angle for gas flow alignment. With an inner diameter of 4 inches and an outer diameter of 6.25 inches, this precision-machined adaptor maintains backpressure balance and improves turbo spool efficiency.

Fabricated from high-temperature resistant steel and finished with anti-corrosion coatings, it ensures long-term durability in both marine and stationary environments. Proper alignment of the turbo riser adaptor is crucial to avoid exhaust leaks and maintain consistent boost pressure in the 12V92 Turbo engine system.

Manifold Insulation Tape – 3” and 4”

Exhaust manifold insulation is vital for managing heat radiation and protecting surrounding components from excessive temperature exposure. Manifold insulation tape, available in 3-inch and 4-inch widths, is designed to wrap around exhaust pipes, manifolds, or turbo risers to contain radiant heat and improve efficiency.

Each roll provides 100 feet of coverage at 1/8-inch thickness—ideal for marine engine rooms where space is confined and ventilation is limited. The insulation not only improves safety but also contributes to better turbo performance by keeping exhaust gases hotter for longer, which helps sustain exhaust velocity and reduces turbo lag.

Diesel Pro Power’s insulation tapes are resistant to oil, water, and salt corrosion, making them ideal for offshore vessels, industrial generators, and performance-driven rebuilds.

Detroit Diesel Marine Exhaust Fittings – Elbows, Plates, and Gaskets

Marine exhaust systems on the 12V92 Turbo often require precision fittings to ensure watertight and heat-resistant connections between manifolds, elbows, and risers. Diesel Pro Power carries a full range of these components:

• Threaded Plates (3/4” Thread): Used to close manifold access points or to connect auxiliary lines in water-cooled manifolds.

• 90° and 45° Marine Elbows: Available in both 3/4-inch and 1-inch threaded options, these elbows are built from marine-grade bronze or stainless steel, designed to withstand continuous exposure to saltwater and exhaust temperatures exceeding 1,200°F.

• Marine Manifold Gaskets: Such as the flange spacer gasket and JT92 marine gasket, each designed for perfect fitment on 12V92 marine manifolds. These gaskets provide a reliable seal against high-temperature gas and water mixture leaks, preserving system pressure and preventing corrosion.

Each gasket and fitting has been pressure-tested for marine applications to ensure durability under extreme load cycles typical of commercial vessels and workboats powered by the Detroit Diesel 12V92T.

Detroit Diesel Muffler Caps and Exhaust Termination Components

Proper exhaust termination is vital for directing gases safely out of the engine compartment. Diesel Pro Power offers muffler caps in multiple sizes—4”, 5”, and 6”—for various Detroit Diesel industrial engines. These caps protect against debris intrusion, water backflow, and corrosion buildup.

Each cap is precision-formed from corrosion-resistant steel and fits securely over the exhaust pipe. Commonly used in stationary power generators and land-based applications, these components help preserve engine efficiency and maintain clean emissions discharge.

Flexible Metal Exhaust Hoses – 6” x 18” and 8” x 18”

The flexible metal exhaust hoses are essential for reducing vibration and aligning exhaust systems in tight installations. Available in two configurations—6x18 inches and 8x18 inches—these hoses are designed to handle high heat, vibration, and backpressure found in Detroit Diesel 12V92T engines.

The corrugated stainless-steel construction allows flexibility without compromising strength, making them suitable for both marine and industrial installations. Using flexible connections prevents strain on exhaust manifolds and turbocharger housings, significantly extending their service life.

Temperature Switch for Detroit Diesel, Cummins, and Caterpillar Engines

Temperature management is crucial in turbocharged engines like the 12V92T. The temperature switch, designed for Detroit Diesel, Cummins, and Caterpillar engines, automatically triggers alerts or cutoffs when the system temperature reaches 205°F.

With a standard 1/2" NPT thread, it fits seamlessly into most engine blocks or coolant housings. This component helps prevent overheating damage to exhaust valves, turbo bearings, and manifolds—critical in high-demand environments such as marine propulsion or industrial power generation.

Detroit Diesel Green Engine Paint

Finishing your engine rebuild with Detroit Green Paint not only preserves the iconic look of the Series 92 engine but also offers corrosion resistance and thermal protection. Suitable for all Detroit Diesel two-stroke engines, this enamel-based paint withstands high temperatures and oil exposure, keeping your engine compartment professional and clean.

This paint is available for ground shipping throughout the USA and Canada and is widely used by marine engineers, fleet maintenance teams, and restoration specialists to maintain OEM appearance and protection.
