Here's why:
* Engine Mounts: While the engine block itself *might* be largely the same, the engine mounts (the parts that attach the engine to the car's frame) could be different between the 1995 and 2001 models. Even a small difference could prevent a direct fit.
* Wiring Harness and Computer: The engine's wiring harness and the car's computer system (PCM) are likely incompatible. The 2001 model will have a more modern system that may not be able to communicate with the 1995 engine's components. This is a major hurdle.
* Exhaust System: The exhaust manifold and system may not be compatible.
* Accessories: The placement of accessories like the alternator or power steering pump might differ slightly, causing interference.
In short, while the *possibility* exists, it's not a simple bolt-in swap. You'd need to extensively compare the engine bay components of both cars to determine compatibility. It's likely significantly more work than it's worth unless you're experienced with engine swaps and have access to all the necessary parts (including potentially a custom wiring harness). You'd be better off sourcing a 3.3L from a similar-year Intrepid.
