Turbocharger GTA3782BD for International 4700 4900 (1993-2001) 7.6L 8.7L

Direct-Replacement GTA3782BD Turbocharger for 1993-2001 International 4700,4900 (4000 Series)

What it Does: The GTA3782BD turbocharger replaces failed or worn factory turbos on 1993-2001 International 4700 and 4900 trucks to eliminate boost leaks, restore factory manifold pressure, and recover lost pulling power under heavy payload.

The Stock International 4700,4900 Journal Bearing and Oil Seal Degradation

Under continuous heavy-haul duty cycles, the factory turbo on the DT466 and DT530 platforms suffers from severe thermal fatigue, carbon coking in the oil-feed passages, and excessive axial thrust bearing play. Over extended operating hours, worn dynamic oil seals allow pressurized oil to leak past the turbine housing, leading to chronic blue or black exhaust smoke, low boost pressure, severe compressor wheel rub, and pronounced whistling noises under throttle load.

The Engineering Solution

Engineered to exact OEM tolerances, this GTA3782BD unit integrates a robust ductile cast-iron turbine housing, high-flow cast-steel compressor housing, and a dedicated journal bearing assembly paired with an oil-cooled center housing rotating assembly (CHRA). The pre-calibrated internal wastegate actuator precisely limits peak boost creep to safeguard head gaskets, while factory-spec oil ports and turbine inlet flanges ensure drop-in alignment with OEM charge pipes and exhaust manifolds without structural modification.

What's Included

• 1 Turbocharger with Wastegate Actuator

Frequently Asked Questions & Fitment Warnings

Does this fit the 4000 Series 4700,4900?

Yes, this is a direct fit for the 1993-2001 International 4700,4900 equipped with the DT466, DT466E, or I530E diesel engines matching the listed OEM part numbers.

Do I need to prime the turbocharger prior to starting?

Yes, fill the center housing oil feed port with fresh clean engine oil and rotate the shaft by hand before initial start to prevent immediate dry-bearing scuffing.

The International Heavy-Duty Standard

Engineered for commercial-grade longevity, this turbocharger withstands the continuous heat and high-exhaust backpressure demands of heavy fleet hauling, commercial towing, and regional vocational operations.
