To achieve 500 HP, several modifications are necessary, including upgraded turbos and internal components.
Key Components for the Build
- BorgWarner S256SX Turbos
- Forged Internals (pistons, rods, crankshaft)
- Upgraded Fuel System
- ECU Tuning
- Intercooler Upgrade
- Exhaust System
BorgWarner S256SX Turbos
The BorgWarner S256SX turbos are a popular choice for those seeking high power levels. They offer excellent spool characteristics and can support the desired horsepower. The cost for a pair of these turbos typically ranges from $1,800 to $2,200.
Forged Internals
Upgrading to forged internals is essential for handling the increased power levels. This includes forged pistons, connecting rods, and a crankshaft. The total cost for these components can range from $1,500 to $2,500, depending on the brand and specifications.
Additional Modifications
To support the increased airflow and fuel demands, several additional modifications are necessary. These upgrades ensure that the engine runs efficiently and reliably at higher power levels.
Upgraded Fuel System
An upgraded fuel system is critical for achieving the desired horsepower. This includes high-flow fuel injectors and a fuel pump capable of supporting the increased fuel demand. The cost for these upgrades can range from $600 to $1,200.
ECU Tuning
Proper ECU tuning is necessary to optimize the engine’s performance with the new components. This ensures that the air-fuel mixture and ignition timing are set correctly. Expect to pay between $500 and $1,000 for professional tuning services.
Intercooler Upgrade
An upgraded intercooler helps to reduce intake temperatures, improving performance and reliability. A quality intercooler can cost between $300 and $800, depending on the brand and design.
Exhaust System
A high-performance exhaust system is essential for improving airflow and reducing back pressure. Upgrading the exhaust can cost anywhere from $500 to $1,500, depending on the materials and design.
Total Cost Breakdown
Here’s a summarized cost breakdown for building a 500 HP N54 turbo setup:
