* Fuel System Upgrades: A turbocharger drastically increases airflow, requiring a much richer fuel mixture. This often means upgrading the fuel injectors, fuel pump, and possibly adding a fuel pressure regulator.
* Engine Management System: You'll likely need a programmable engine control unit (ECU) to properly manage the increased fuel and air flow, timing, and boost pressure. A standalone ECU is often preferred for extensive modifications.
* Exhaust System: A properly sized exhaust manifold and downpipe are crucial for efficient turbocharger operation. Restricting the exhaust flow will severely limit performance and potentially damage the engine.
* Intercooler: An intercooler is essential to cool the compressed air coming from the turbocharger, significantly reducing intake air temperatures and preventing detonation.
* Strengthened Internal Components: The increased power and stress from the turbocharger can quickly overwhelm stock internal components. This might necessitate upgrading the connecting rods, pistons, and possibly the crankshaft to handle the extra power.
* Oil System Upgrades: Turbos require adequate lubrication, and higher oil pressure may be necessary. An upgraded oil pump may be needed.
In short: While it's possible, turbocharging a Chevy 350 is a complex and potentially expensive project. It's not a simple bolt-on modification and requires considerable mechanical knowledge and expertise, or the services of a qualified engine builder. Improper installation or insufficient supporting modifications can lead to engine damage.
