Custom Fuel Injection Systems for Classic Cars

Revitalizing Classics with Modern Fuel Injection

At Greg’s Classics and Performance, we specialize in blending old-school charm with cutting-edge technology. Our custom fuel injection systems bring the reliability, efficiency, and performance of modern engines to classic cars, ensuring they maintain their vintage allure while running like a dream. Whether you’re looking for improved drivability, increased horsepower, or better fuel economy, our team has the expertise to make it happen.

The Process: Transforming Carbureted Classics to EFI

Transitioning from a carburetor to an electronic fuel injection (EFI) system requires precision and expertise. Here’s how we do it at Greg’s Classics and Performance:

1. Consultation and Assessment

Every project begins with a detailed consultation where we discuss your goals, driving habits, and performance expectations. We assess the current engine setup and determine the best EFI system to suit your classic car.

2. Selecting the Right EFI System

Not all EFI systems are created equal, and choosing the right one depends on several factors, including:

• Engine type and displacement
• Desired horsepower and torque improvements
• Fuel system compatibility
• Budget and customization preferences

We work with top-tier brands such as Holley Sniper EFI, FiTech, and FAST to ensure your classic car gets the most reliable and high-performance setup.

3. Fuel System Upgrades

For a successful EFI conversion, we upgrade the fuel system to accommodate high-pressure fuel delivery. This includes:

• Installing a high-pressure electric fuel pump
• Upgrading to EFI-compatible fuel lines
• Adding a fuel pressure regulator
• Installing a return-style or returnless fuel system based on your vehicle’s setup

4. Throttle Body or Multi-Point Injection Setup

Depending on the engine and customer preference, we offer:

• Throttle Body Injection (TBI): A simpler setup that replaces the carburetor with a throttle-body-style injector system.
• Multi-Point Fuel Injection (MPFI): A more advanced system where fuel injectors are placed at each cylinder, offering better fuel atomization and efficiency.

5. ECU and Sensor Integration

Modern EFI systems require precise data input for optimal performance. We install and configure:

• Engine Control Unit (ECU): The brain of the EFI system, responsible for managing fuel delivery and air-fuel ratio adjustments.
• Oxygen Sensors: Help the ECU monitor and optimize the fuel mixture.
• Throttle Position Sensor (TPS): Ensures smooth throttle response.
• Coolant Temperature Sensor: Helps with cold-start enrichment and engine protection.

6. Wiring and Tuning

Wiring is a critical part of EFI installation. We ensure a clean and professional wiring job by using high-quality harnesses and connectors. Once installed, our tuning experts dial in the fuel maps and ignition timing for optimal performance, ensuring smooth idle, crisp throttle response, and efficient power delivery.

7. Road Testing and Fine-Tuning

Before we hand the keys back, we conduct real-world testing to ensure everything runs flawlessly. We monitor performance data, make any necessary adjustments, and fine-tune the system to deliver the best balance of power and efficiency.

Benefits of EFI Conversion

Upgrading to a custom EFI system with Greg’s Classics and Performance provides numerous benefits:

• Improved fuel economy compared to carbureted setups.
• Increased horsepower and torque with optimized fuel delivery.
• Reliable cold starts without the need for choke adjustments.
• Smoother throttle response for a better driving experience.
• Reduced emissions with precise air-fuel management.
• Minimal maintenance compared to traditional carburetors.
