Carbureted & EFI For Increasing Performance

High-Performance EFI Auto Repair in Portsmouth

The expert mechanics at John's Service 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, John's Service 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 John's Service Center and talk to us about increasing your car's performance. When you want performance you need the auto repair experts at John's Service Center located at 4650 Portsmouth Blvd.

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

Tuning Old School Carburetors For True Muscle

Your muscle car may be starving for air! Bring it to John's Service 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. John's Service 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 John's Service Center at 4650 Portsmouth Blvd 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? John's Service 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 757-488-1964!

Testimonials

I was looking for a reputable repair shop to take my car for service. My neighbors recommended John's. I first took my car for state inspection and oil/filter change. I was in and out in less than an hour. On another occasion my son thought he needed a battery for his truck. We stopped in at John's as he was going to lunch, but he took the truck in and replaced the battery. My wife took her car to several local shops including some dealerships due to a loud roar in the front. She was told she needed a hub bearing. The price of repair ranged from 600-800 dollars and about 4hrs to perform the repairs. I took her car to John's who was booked full all week. I explained my wife had to go out of town for Christmas and was afraid to drive it with a bad bearing. I was told to bring it in tomorrow morning. He did the work for less than all the other shops and completed the work in about two hours. Again, this shows a business that cares about customer satisfaction. Needless to say, John's Service Center has won over my entire family and we have found a place that appreciates our business. I highly recommend this company to anyone looking for a decent place to service your vehicle needs.
