Roush, Edelbrock, Chevrolet and More

Roush Engines

Combining engineering with racing, Roush founded Roush Performance Engineering in 1976 and began selling high-performance engine designs to the world of motorsports. His racing team's ability to win and a brilliant solution-oriented approach to building engines earned Roush a reputation associated with excellence.

Edelbrock Engines

Edelbrock engines are known for research and development, manufacturing, and state-of-the-art testing facilities. Racing enthusiasts have called the Edelbrock manufacturing approach "the most state-of-the-art" in the United States. Founder Vic Edelbrock Sr. bought his first project car, a 1932 Ford Roadster, and designed a specialty engine and intake manifold that instantly became a sensation in the world of "hot rods" and racing.

Chevrolet Engines

Chevrolet Performance began engineering high-performance crate engines 50 years ago and today continues to manufacture new horsepower focused engine designs with a distinctly American sound. Chevrolet offers full crate engine drop-in kits to help high-performance car drivers get back to leading the pack fast.

What People Say About Us

  • reviewicon

    I've had Tim (ASE Master Technician) and Nate work on my vehicles and they've always done great work at reasonable prices. Before I recently traded my old Pontiac Vibe in to the dealer, I had these guys get everything in tip top condition and Kocourek gave me a really good price. When my son was up here visiting, the heat shield bracket to the muffler had come loose and was making a terrible noise. These guys knew exactly what it was, got it up on the lift and 10 minutes later, finished. $10 bucks. All without an appointment. I've seen big rigs in there, so they know what they're doing. Highly recommended.

    This is easily the best auto service within Marathon county, and I've been everywhere. The customer service is on par with a 5 star resort and hotel. Also when shopping around for the lowest price on a job or repair, this place always maintains the best price.

    I brought my Mercedes into West Side for the first time and they did a great job diagnosing and addressing my issue in a timely and professional manner. Staff is extremely accomodative and friendly as well as seemingly immensely knowledgeable. I no longer live in Wausau but if I did West Side Automotive would be my 'go to' shop for automotive-related repairs. Highly recommended.

    I was on my way home to Madison when handling problems with my car started. Even though it was Friday, and snowing, Tim got me in right away. I was back on the road in short order. The price was very reasonable and they also have the best waiting area I've experienced! Thank you very much!
