Supercharger

The Eaton M90 supercharger (OEM part number 204873) is engineered to boost performance for 3.8L engines found in select GM vehicles, including Pontiac GTP, Buick, and Chevrolet models. This belt-driven unit features a Twin-Scroll design, contributing to improved efficiency and power delivery. This supercharger is specifically noted for its application on the GM 3800 series V6 engines, commonly found in vehicles from 1992-2007. While it is a direct-fit for many 3.8L L67 applications, it's important to note that the L67 Lower Intake Manifold (LIM) may not fit on all Buick V6 engines due to differences in intake port layout and deck height. Compatibility should be verified for specific Buick V6 applications beyond the L67, as some may have utilized the M62 supercharger instead. As a used component, its condition and operational status should be carefully assessed by the buyer. The "Parts Unit" designation in some listings indicates potential need for refurbishment or that it's intended for parts extraction.
