Workshop 5001

Workshop 5001 was founded in 2014 by Marlon Goldberg alongside technician John Bowman in Los Angeles, California. Goldberg, who had previously trained at East Coast luxury marques, apprenticed under legendary Porsche engine builder Andial, and served as an early project manager at Singer Vehicle Design, sought to establish an independent studio where engineering substance took precedence over exterior ornamentation. Operating out of a converted mid-century manufacturing facility located at 5001 West Exposition Boulevard—which lent the shop its name—the company introduced its philosophy with its flagship commission, "Number 1," an understated 1972 Porsche 911 F-Model sleeper equipped with a custom 3.4-liter twin-plug powerplant. This set the benchmark for their numbered ground-up builds and specialized mechanical packages. Over the ensuing decade, Workshop 5001 developed a reputation for extreme attention to detail, offering bespoke engine development (ranging from high-revving naturally aspirated 3.9-liter strokers to advanced twin-turbocharged platforms), full ground-up restorations, and specialized Sports Purpose Makeovers (SPM). Today, the workshop remains deliberately small-scale and owner-operated, catering to discerning global collectors who prioritize driving dynamics and modern aerospace craftsmanship.
