* Engine Reinforcement: The Hemi engine needs significant reinforcement to handle the increased stress of forced induction. This includes stronger internals like connecting rods, pistons, and possibly a stronger block.
* Fuel System Upgrades: The fuel system needs to be substantially upgraded to provide the increased fuel flow required for a turbocharged engine. This likely means a high-pressure fuel pump, larger injectors, and upgraded fuel lines.
* Exhaust System: A custom exhaust system, including a properly sized turbocharger exhaust manifold and downpipe, is essential.
* Cooling System Upgrades: The cooling system must be significantly upgraded to handle the extra heat generated by the turbocharger. This may include a larger radiator, upgraded water pump, and potentially an auxiliary cooling system.
* Engine Management System: The engine management system (ECU) needs to be retuned to accommodate the turbocharger and the changes to fuel delivery, ignition timing, and other parameters. This often involves a standalone engine management system rather than relying on the original system.
* Transmission and Drivetrain: The transmission and drivetrain also need to be evaluated and potentially upgraded to withstand the increased power output.
In short, turbocharging a Hemi 'Cuda is a complex and expensive project requiring specialized knowledge and expertise. It's not something a novice mechanic should attempt. The cost could easily exceed the value of the car if not done properly.
