At Riverside Performance Engines, we’ve been building high-performance and hardworking engines for over 50 years—engines trusted by racers, farmers, business owners, and industries around the country. From custom gas builds to full diesel engine overhauls, our work is built to outlast, outperform, and stand the test of time.

What started as a small machine shop under the leadership of Tom Booth has grown into a full-service engine facility known for clean room assembly, CNC machining, and over 300,000 engines built. Tom’s attention to detail and commitment to quality laid the foundation for everything we do. Though Tom is no longer with us, his legacy continues to drive us forward with the same passion, precision, and pride.

Today, Riverside is led by Mariella Booth, who brings fresh vision and the same deep-rooted values her father instilled. Under her leadership, we’ve expanded into diesel engine rebuilds and continue investing in cutting-edge technology to better serve industries like:

• Performance Automotive

• Agriculture & Heavy Equipment

• Industrial & Manufacturing

• Natural Gas & Energy

• Commercial Fleets & Transportation

Whether you’re restoring a classic car, rebuilding a diesel for your fleet, or machining heads to exact spec, Riverside is your trusted partner from start to finish. All services are performed in-house, ensuring total quality control, faster turnaround times, and no compromises.
