What EngineQuest does
EngineQuest LLC is a privately-held, family-owned engine parts distributor founded in 1949 and headquartered in Las Vegas, Nevada. The company specializes in new castings and aftermarket engine components for automotive, marine, performance, industrial, and forklift applications, with a product portfolio of nearly 600 SKUs across 21 categories including cylinder heads, engine blocks, timing covers, oil pans, flywheels, harmonic balancers, valve train components, head bolts, LS-specific parts, marine components, and forklift/industrial parts. Its flagship product, the EQ-CH364X hybrid LS cylinder head, was endorsed by Hot Rod Magazine as a 'game changer' for budget-minded performance builders, and the company also produces IMCA-sanctioned cast iron performance heads for the racing market.
EngineQuest generates revenue through direct hardware sales of new engine parts, with products priced individually (ranging from $12 plugs to $925-$995 cylinder heads and $1,000+ conversion jigs), often with shipping included and early-payment discounts available on new parts. The go-to-market motion is sales-led and omnichannel: customers purchase via phone (800 and 702 numbers, 7:30am-4:00pm PST), through the company's website, or via its established eBay storefront. Customer segments span performance engine builders seeking discontinued or hard-to-find OEM components, marine engine repair, industrial/forklift equipment, and motorsports racing teams, with the IMCA sponsorship serving as a top-of-funnel brand-building channel.
In October 2025, EngineQuest underwent a significant restructuring, spinning off its Cores & Recycling division into a separate entity (EQ Cores and Recycling LLC) under new ownership led by former VP Juan Haro. EngineQuest LLC now operates exclusively as the New Parts business from a new state-of-the-art facility at 2942 Lincoln Rd, Las Vegas, NV, with no institutional investors or external funding involved. The company employs 11-50 people and serves customers across the western United States and western Canada.

- Trick Flow Specialties: Manufacturer of high-performance cylinder heads, intake manifolds, and engine components specializing in GM LS and SBC platforms. Highly comparable to EngineQuest's flagship LS and SBC cylinder head offerings, with similar emphasis on engineered castings for racing and performance builders.
