High-Performance EFI Auto Repair in Morrow
The expert mechanics at McNabb Speed Shop 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, McNabb Speed Shop can add a new stock-height replacement intake manifold, cold air intake, and fuel rails.
