* Engine Compatibility: The Sebring's naturally aspirated engine wasn't designed for forced induction. You'll need significant modifications to handle the increased stress and pressure a turbocharger introduces. This includes:
* Forged internals: The stock connecting rods and pistons are likely not strong enough to withstand the higher pressures. Upgrading these is crucial to prevent engine failure.
* Larger fuel injectors: More fuel will be needed to support the increased airflow.
* Fuel pump upgrade: The stock fuel pump may not be able to deliver enough fuel under boost.
* Strengthened engine mounts: The increased power and vibrations will put extra stress on the engine mounts.
* Upgraded exhaust system: The exhaust system needs to be able to handle the increased exhaust flow. A larger diameter exhaust system with a free-flowing exhaust manifold is crucial.
* Intercooler: An intercooler is essential to cool down the compressed air, preventing detonation (premature ignition) and improving performance.
* Engine management system (ECU) tuning: This is arguably the most critical aspect. The ECU needs to be reprogrammed to adjust fuel delivery, ignition timing, and other parameters to work correctly with the turbocharger. This often requires custom tuning, which is a specialized service.
* Cost: The cost of all these modifications can easily exceed the value of the car. You'll need to factor in the cost of the turbocharger kit (if you can even find one specifically designed for this engine, which is unlikely), labor for installation, parts, and professional tuning.
* Complexity: This is not a project for someone with limited mechanical experience. Incorrect installation or tuning can lead to severe engine damage.
In short: While technically possible, it's a major undertaking requiring significant mechanical knowledge, specialized tools, and a substantial financial investment. It's likely to be far more expensive and complex than it's worth for a 2002 Sebring. The cost of the modifications might far exceed the car's resale value. Consider the overall cost and feasibility before proceeding. You'd likely be better off buying a car that already has a turbocharger.
