Carbureted & EFI For Increasing Performance

High-Performance EFI Auto Repair in St. Johns

The expert mechanics at RTL Auto Repair know switching to fuel injection often improves the fuel efficiency and performance of older carbureted engines. In newer cars, replacing a single fuel injector with a multi-port fuel injector creates an intense, even flow of fuel on each cylinder when your engine needs it most. Feed your engine the fuel it needs with fuel pumps, fuel filters, superchargers, and turbochargers. Break out of gasoline only feed engines by adding a nitrous kit or cooling methanol injection kit.

To ensure the correct air to fuel ratio, RTL Auto Repair can add a new stock-height replacement intake manifold, cold air intake, and fuel rails. Never run rich or lean with a hood scoop, high-performance air filter, and new O2 sensor. Call RTL Auto Repair and talk to us about increasing your car's performance. When you want performance you need the auto repair experts at RTL Auto Repair located at 909 E State St.

If you're ready to take your car or truck's fuel injection to the next level, RTL Auto Repair is ready with injectors, manifolds, fuel rails, sensors, and complete performance EFI conversion kits. From BMW to Audi to Corvette, RTL Auto Repair has you covered.

Tuning Old School Carburetors For True Muscle

Your muscle car may be starving for air! Bring it to RTL Auto Repair and find out. Because of operating losses in the intake runner and cylinder with newer unleaded fuels that do not fully vaporize in the combustion chamber, cars tuned to the manufacturer's specifications can run lean. RTL Auto Repair can diagnose if you are actually running leaner than the manufacturer suggested ratio of 14.7:1 air to fuel mixture. Bring your classic car to RTL Auto Repair at 909 E State St to tune the perfect air to fuel mixture and correct ignition spark for maximum power.

What Our Customers Are Saying

Our family has taken cars to Rick at RTL for probably 20 years. Rick is like an encyclopedia for car trivia. He has always been extremely fair and honest with us, offering lower cost options to expensive repairs. I know that I will get accurate information and the best value from Rick. The used car inspection for $35 is absolutely invaluable. I recommend RTL regularly!
