Electronic Fuel Injection

Carbureted & EFI For Increasing Performance

High-Performance EFI Auto Repair in Gillette

The expert mechanics at Northwest Performance & Machining 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, Northwest Performance & Machining 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 Northwest Performance & Machining and talk to us about increasing your car's performance. When you want performance you need the auto repair experts at Northwest Performance & Machining located at 905 W 1st St.

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

Tuning Old School Carburetors For True Muscle

Your muscle car may be starving for air! Bring it to Northwest Performance & Machining 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. Northwest Performance & Machining 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 Northwest Performance & Machining at 905 W 1st St to tune the perfect air to fuel mixture and correct ignition spark for maximum power.

What People Say About Us

    Left my car there while on vacation, kept me informed, car runs great. Fixed a seal, stopped oil leaking, and established I needed a new battery. Thank you, Tracy and Linda Norris!

    Got us in last minute for some repairs that could have been catastrophic if we continued down the road. They could have easily gouged us knowing we were in a pinch and just trying to get home but were upfront, honest and personable. Would recommend to anyone.

    Incredibly impressed with the service and how informative our experience was. They were able to get us in on very short notice and explained to us exactly what was going on with my car. I definitely plan on coming back for any mechanical needs that we may have in the future.

    This shop is absolutely fantastic. These guys went out of their way to fix our problem. We are from Spokane Washington and we needed to get home. These guys worked outside in 30 degree weather to fix our RV so we can make it home. If I'm ever in the area again and need work done these are the first guys that I will go to, to have it completed. The owner even went out of his way to call me to make sure that I made it home okay. Thank you so much for going out of your way to make sure that I made it home and our RV was repaired.

    Great staff!! Great service!! Had a emergency while traveling and showed up one morning with some work needing to be done and was able to fit me in and get it done. Had my own parts and price was very reasonable. Would definitely recommend this shop.

    Cole is great to work with! I had a problem with my wife's care and he was able to find the issue and replace the part. I was able to use the car while we waited for parts. Every aspect of their work was great.

    Friendly, straightforward, and honest. We were just traveling through and I feared some kind of up sell. Nothing like that happened. I wish I lived in Gillette so I could take my car there all the time.
