* Engine Compatibility: The 1997 Eclipse RS came with a 2.0L naturally aspirated engine (4G63). While it's technically possible to swap in a turbocharged engine, the engine mounts, transmission, and other components may not be compatible.
* Engine Bay Space: The 1997 Eclipse RS has a relatively compact engine bay. A turbocharged engine, particularly a 1997cc, might be too large for the space.
* Electrical System: The wiring harness and ECU (Engine Control Unit) for the 1997 RS are designed for the naturally aspirated engine. The turbocharged engine's electrical system may require major rewiring and a new ECU.
* Transmission Compatibility: The transmission designed for the naturally aspirated engine might not be strong enough to handle the added power and torque of a turbocharged engine.
What You Need to Consider:
* Engine Choice: If you're determined to swap engines, you'll need to research specific engines that might fit, like the 4G63T (turbocharged) from other Eclipse models.
* Modifications: Be prepared for extensive modifications, including new engine mounts, exhaust system, intercooler, plumbing, and potentially even a custom wiring harness.
* Expertise: This is a significant project. It's best to seek the help of experienced mechanics or engine swap specialists.
Alternatives:
* Forced Induction: You could consider adding forced induction (turbocharger or supercharger) to your existing 2.0L engine. This would be a more straightforward approach than a full engine swap.
* Engine Upgrades: If you're looking for more power, consider other performance upgrades for your existing engine, like a better exhaust, intake, or engine management system.
In Conclusion:
Swapping in a 1997cc DOHC turbo 16-valve engine into a 1997 Mitsubishi Eclipse RS is a challenging project that requires extensive modifications and expertise. Before embarking on such a project, it's essential to carefully weigh the challenges and potential costs against the benefits.
