Carbureted & EFI For Increasing Performance

High-Performance EFI Auto Repair in Tucson

The expert mechanics at Simmons 4x4 Automotive Repair Center 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, Simmons 4x4 Automotive Repair Center 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 Simmons 4x4 Automotive Repair Center and talk to us about increasing your car's performance.

Tuning Old School Carburetors For True Muscle

Your muscle car may be starving for air! Bring it to Simmons 4x4 Automotive Repair Center 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. Simmons 4x4 Automotive Repair Center 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 Simmons 4x4 Automotive Repair Center at 3743 S Country Club Rd to tune the perfect air to fuel mixture and correct ignition spark for maximum power.

Need to replace your old four-barrel carburetors or hack your hood with tunnel rams? Simmons 4x4 Automotive Repair Center will help you choose the Holley, Edelbrock, Barry Grant, or Quick Fuel carburetor and air intake system that is right for your car. Call us today at 520-884-0217!
