Product Overview:
This is a TD04L6 turbocharger from Mitsubishi Heavy Industries, engineered to OEM specifications for GM’s 2.0L LTG turbocharged Ecotec engine used across a wide range of Buick, Chevrolet, and Cadillac models. It restores factory boost pressure, throttle response, and power delivery for vehicles suffering from turbo lag, power loss, unusual whining/grinding noise, oil leaks, or a fully failed unit — common wear points as these engines reach higher mileage.
Key Features:
- OEM-Matched Fitment: Manufactured to match the mounting configuration and flange dimensions of the original 49377-07831 turbocharger for a direct bolt-on replacement.
- Genuine MHI TD04L6 Platform: The factory-fitment turbo design used across GM’s 2.0L LTG engine lineup, known for a strong balance of daily-driving reliability and boost response.
- Electronic Actuator Included: Comes equipped with the factory-style electronic wastegate actuator for precise, computer-controlled boost regulation (confirm inclusion with your specific listing).
- Water + Oil Cooled Design: Matches the factory dual-cooling bearing housing specification for improved thermal management and long-term durability.
- Complete, Ready-to-Install Unit: Supplied as a full turbocharger assembly with flange and oil-hole gaskets included in many kits.
- Restores Lost Power & Efficiency: Addresses common failure symptoms — severe power loss under acceleration, blue/white exhaust smoke, and unusual turbo noise.
- Warranty: Typically 6-month to 1-year manufacturer warranty depending on supplier (confirm specific terms with your listing).
- Note on Upgrade Variants: Some suppliers also offer “G25-550” ball-bearing hybrid upgrade versions of this turbo for tuned applications. If you’re selling stock-replacement units, clarify that yours is OEM-spec to avoid confusion with these performance variants listed under the same part number.
Before You Buy:
Please confirm the part number stamped on your original turbocharger (49377-07831 vs. the closely related 07800/07810/07820/07821/07822/07823 family) against your vehicle’s exact model, trim, and production year, since GM’s LTG 2.0T turbo applications span many badge-shared vehicles with closely related part number variants. We also recommend diagnosing the root cause of any prior turbo failure (e.g., oil supply issues) before installation, and recommend professional installation. Let us know your vehicle’s VIN if you’d like help verifying exact compatibility before ordering.
