Building a car engine to enhance performance is an exciting challenge for automotive enthusiasts. This guide will explore how to increase horsepower from 130 HP to 170 HP using reputable brands like HKS, Greddy, and Cosworth. With the right modifications, you can achieve significant power gains while maintaining reliability.
Understanding Your Engine
Before diving into modifications, it’s crucial to understand the fundamentals of your engine. Knowing your engine type, current specifications, and limitations will help tailor your build effectively. Most engines can benefit from the following areas:
- Air intake system
- Exhaust system
- Fuel system
- Tuning and engine management
Step 1: Upgrading the Air Intake
The air intake is a vital component for increasing horsepower. A high-performance intake can improve airflow, allowing your engine to breathe better. Brands like HKS and Greddy offer quality options that can significantly enhance intake efficiency.
- HKS Super Power Flow Intake System: This system is designed to increase airflow and improve throttle response.
- Greddy Airinx Air Filter: A high-flow air filter that can be used with stock or aftermarket intakes.
Step 2: Upgrading the Exhaust System
An efficient exhaust system is just as crucial as the intake. Upgrading to a performance exhaust can reduce back pressure and improve exhaust flow, resulting in better power output. Consider the following options:
- HKS Hi-Power Exhaust System: Known for its high flow and deep sound, this exhaust system is a favorite among enthusiasts.
- Greddy Revolution RS Exhaust: This system combines performance with a sleek design, enhancing both power and aesthetics.
Step 3: Upgrading the Fuel System
To support increased horsepower, your engine will require more fuel. Upgrading the fuel injectors and fuel pump will ensure adequate fuel delivery. Here are some recommended upgrades:
- Cosworth Fuel Injectors: High-performance injectors that provide improved fuel atomization and flow rates.
- Walbro Fuel Pump: A reliable pump that can support higher horsepower levels with increased fuel delivery.
Step 4: Engine Tuning and Management
After upgrading the intake, exhaust, and fuel systems, proper tuning is essential to maximize performance. Engine management systems can adjust fuel maps, ignition timing, and other parameters. Consider these options:
- HKS F-Con V Pro: A sophisticated engine management system that allows for extensive tuning capabilities.
- Greddy E-Manage Ultimate: A versatile tuning tool that can optimize your engine’s performance with various settings.
Step 5: Additional Performance Enhancements
Beyond the primary upgrades, several additional modifications can further enhance performance:
- Upgraded Intercooler: If your engine is turbocharged, a larger intercooler can help reduce intake temperatures.
- Performance Camshafts: Upgrading camshafts can improve airflow and increase power at higher RPMs.
- Lightweight Flywheel: Reducing rotational mass can improve throttle response and acceleration.
Conclusion
Increasing your engine’s horsepower from 130 HP to 170 HP is a challenging yet rewarding project. By carefully selecting components from trusted brands like HKS, Greddy, and Cosworth, you can achieve your performance goals. Always remember to tune your engine properly after modifications to ensure reliability and efficiency.
