About EngineQuest
Built on Legacy. Driven by Innovation.
EngineQuest is your trusted source for engine parts, core supply, and non-ferrous recycling. With decades of industry experience, a strong focus on quality, and a deep understanding of what today’s engine builders need, we proudly serve customers in the automotive, performance, marine, industrial, and forklift markets.
Our story began in 1949, when Aaron and Alex Stolberg started sourcing engine and transmission cores in Chicago. Over the decades, our business has grown and evolved, with major distribution centers in Las Vegas and Chicago, and a strong reputation among engine professionals nationwide.
Today, EngineQuest operates as a unified company from our Las Vegas HQ, combining decades of engine parts manufacturing experience with our core and recycling divisions to offer more than just parts. We deliver solutions.
