Can you put a 3.8 supercharger on a 3.4 engine?

Yes, you can install a 3.8 supercharger on a 3.4 engine, but it requires modifications and proper tuning to ensure compatibility and performance. The two engines may have different mounting points, intake systems, and fuel requirements, so you would need to address these differences. Additionally, ensure that the engine internals can handle the increased boost pressure to avoid damage. Consulting with a professional or an experienced mechanic is advisable for such modifications.
