* No factory turbo setup: The 1996 Probe GT had a naturally aspirated engine. This means there's no existing infrastructure (turbo manifold, oil and coolant lines, wastegate, etc.) to work with. You'll need to source all of these components, which requires significant research and sourcing.
* Engine modifications: A turbocharger significantly increases the stress on the engine. You'll likely need to upgrade the connecting rods, pistons, and possibly the crankshaft to handle the increased pressure and power. This involves significant engine disassembly and rebuilding expertise.
* Fuel system upgrades: The stock fuel system isn't designed for the higher fuel demands of a turbocharged engine. You'll need a higher-flow fuel pump, larger fuel injectors, and potentially a fuel pressure regulator.
* Exhaust system modifications: A turbocharger requires a specialized exhaust manifold and downpipe designed to efficiently route exhaust gases to the turbo. The entire exhaust system might need to be modified or replaced.
* Engine management: The stock engine control unit (ECU) is not designed for a turbocharger. You'll need a standalone engine management system (EMS) or a piggyback system capable of managing the increased boost pressure, fuel delivery, and ignition timing. This requires significant knowledge of engine tuning and management.
* Cooling system upgrades: Turbocharging generates significant heat. You might need an upgraded radiator, intercooler, and possibly other cooling system components to prevent overheating.
* Transmission considerations: The stock transmission might not be able to handle the increased torque produced by the turbocharger. An upgrade might be necessary.
In short, this is a major undertaking requiring significant mechanical skill, specialized tools, and a deep understanding of internal combustion engines and turbocharger systems. It's far easier (and cheaper) to buy a used turbocharged car than to attempt this conversion. Unless you have extensive experience with engine building and tuning, it's best to leave this project to professionals.
