1997 Oldsmobile LSS
Supercharger

Thank you for your inquiry. The supercharger on this listing is a direct replacement and will not add any additional horsepower as it replaces the supercharger originally installed on the 1997 Buick LeSabre from factory.

No, this is only for vehicles which were supercharged from the factory. If you're looking to add a turbo to your vehicle, you would also need an intake manifold, all the other intake components (including the intercooler and vacuum parts), likely some larger fuel injectors, and a custom tune to make it all work reliably. This will also affect your vehicle's reliability, fuel economy and ability to pass any emissions testing. If you'd like a faster car, it would be much easier and probably less expensive overall to simply trade in your vehicle for something faster.

Yes, this supercharger (40-10005 R) fits all 1996 and 1997 Grand prix that had a supercharger from the factory.
