- Turbocharger: A Precision Turbo is recommended for optimal boost and efficiency.
- Fuel System: Upgraded injectors and fuel pump to ensure adequate fuel delivery.
- Exhaust System: A high-flow exhaust to reduce back pressure and improve performance.
- ECU Tuning: A standalone ECU for precise control over engine parameters.
Budget Breakdown
Building a 13B turbo engine requires careful budgeting. Below is a breakdown of estimated costs for each component.
- Engine Block: $1,500
- Turbocharger: $1,800
- Fuel System: $1,200
- Exhaust System: $800
- ECU: $1,000
- Miscellaneous Parts: $1,000
- Labor Costs: $2,700
Performance Goals
With the right components, achieving 320 horsepower from a 13B turbo is feasible. The target is to balance power output with reliability and drivability.
Boost Levels
To reach the desired horsepower, running around 12-15 psi of boost is recommended. This level provides a good balance between performance and engine longevity.
Tuning Considerations
Proper tuning is critical. A well-tuned engine can significantly improve performance and efficiency, ensuring that the engine runs smoothly under various conditions.
Building the Engine
The assembly process is crucial to achieving the desired results. Each component must be installed with precision, ensuring that everything fits correctly and functions as intended.
Step-by-Step Assembly
- Prepare the engine block by cleaning and inspecting for any damage.
- Install the apex seals and rotor components.
- Mount the turbocharger and connect the necessary piping.
- Install the fuel system components, ensuring proper fitment.
- Set up the exhaust system to optimize flow.
- Connect the ECU and finalize all electrical connections.
Testing and Tuning
After assembly, the engine needs to be tested and tuned for optimal performance. This process involves running the engine on a dynamometer to measure power output and make necessary adjustments.
Dyno Testing
Dyno testing allows you to see real-time data on horsepower and torque. It’s essential for fine-tuning the engine’s performance and ensuring it meets the target of 320 hp.
Final Thoughts
Building a 13B turbo engine for 320 hp on a budget of $9,000 is an ambitious project, but with the right planning and execution, it is achievable. By carefully selecting components and focusing on precision, you can create a powerful and reliable rotary engine.
