* No factory provisions: The 1988 Prelude 2.0 Si engine wasn't designed for forced induction. You'll need to fabricate or source many components.
* Engine strengthening: The stock internals (pistons, connecting rods, crankshaft) aren't designed to handle the increased stress of turbocharged operation. Failure is likely without upgrades. This includes potentially needing forged internals for reliability at higher boost levels.
* Fuel system upgrades: The stock fuel injectors and fuel pump won't be able to supply the necessary fuel for a turbocharged engine. Upgraded injectors, a fuel pump, and potentially a fuel pressure regulator are essential.
* Engine management: The stock ECU (engine control unit) isn't designed to control a turbocharged engine. You'll need a standalone engine management system (EMS) or a heavily modified ECU to control fuel and ignition timing accurately to avoid detonation and engine damage.
* Cooling system upgrades: Turbocharging generates significant heat. Upgraded radiator, intercooler, and possibly oil cooler are needed to keep the engine running at safe operating temperatures.
* Exhaust system: A properly sized exhaust manifold and downpipe are crucial for efficient turbocharger operation. This will likely require custom fabrication.
* Turbocharger selection: Choosing the right turbocharger based on your desired power output is important. Too small, and you won't see much power gain. Too large, and the turbo will spool too slowly.
* Transmission: The stock transmission may not be able to handle the increased power output. Upgrades or replacement might be necessary, especially if aiming for substantial power increases.
In short, while it's *possible*, it's a complex and expensive project requiring significant mechanical skills, specialized tools, and a substantial financial investment. It's far beyond a simple "bolt-on" modification. You'll likely need to consult with experienced mechanics or turbo specialists to ensure the project is completed safely and effectively. Improper installation can easily lead to engine damage.
