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. When you want performance you need the auto repair experts at Simmons 4x4 Automotive Repair Center located at 3743 S Country Club Rd.
If you're ready to take your car or truck's fuel injection to the next level, Simmons 4x4 Automotive Repair Center is ready with injectors, manifolds, fuel rails, sensors, and complete performance EFI conversion kits. From BMW to Audi to Corvette, Simmons 4x4 Automotive Repair Center has you covered.
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.
What People Say About Us
I have been using Simmons for a few years now and have always been treated great and had quality auto work. Drive line shop is the best!!!Thanks Simmons
Caring, honest work, fair prices and excellent customer service. This is the only shop I will take my van to!
I was very happy with my service. I have a jeep and I felt they cared for it as well as I would myself.
They consistently provided feedback and followed up on the progress via phone and email.
Well let me just say that this might not be the cheapest place to fix your 4X4 but after this I will say that they are very thorough and professional. They give you a list of things to fix and advise you as to what is critical and what is not. They work with you and are very professional about it. I will have to say that they did miss one thing that I took it in for originally but probably due to them fixing something that they assumed would fix the problem. I do think that it should have been caught before I picked up the truck and drove home necessitating another trip to their shop. BUT, and a big BUT, it was corrected the second time at no charge which I didn't even have to argue for...This is what I call customer service. Mike was a consummate professional in all my dealings with him...Good Job guys, the truck drives beautiful and hopefully for another 3-4 years!!!
Wade was great. They did a complete work up on my partners car. This was the second work up in 2 weeks. I wanted her to take it to Jerry and have a "Second Opinion" on the state of the car. The mechanics found things that need maintenance and others that need repair. Some of them were not even found by first place she took the car to be examined. Like Jerry says on his radio show you get what you pay for and I always tell everyone that Simmons is Worth the cost.
Took our Jeep in for a "death wobble". Assessments and estimates were clear, concise. Excellent communication throughout by email and phone. I would highly recommend!!
