Can you put the supercharger from a 1998 Buick Regal in Oldsmobile Intrigue?

No, you cannot directly put the supercharger from a 1998 Buick Regal GS (the only Regal with a supercharger that year) into an Oldsmobile Intrigue. While both cars might share some General Motors components, the engine mounts, supercharger mounting points, and associated plumbing (intake, exhaust, etc.) are significantly different and incompatible. The supercharger itself is also specific to the Series II 3800 engine in the Regal GS and won't simply bolt onto the Intrigue's engine. Even if you could overcome the mounting issues, the engine management systems would be entirely different and require extensive custom work (likely beyond the capability of most hobbyists). It's a major undertaking that's impractical and likely not cost-effective.
