Ultimately, the decision to rebuild the supercharger depends on your personal circumstances, including your budget, mechanical expertise, and desired level of performance.

Recommendation:

If you decide to proceed with a supercharger rebuild, carefully research the process and the specific rebuild kit you plan to use. Ensure you have all the necessary tools and a solid understanding of the steps involved.
