Our History

Vintage V12’s has been putting the heart back into World War II fighters since 1981. Current owner, Jose Flores, started working in the shop at age 16 and always had a love of these mechanical works of art, plus a passion for restoring and racing Merlin, Griffon and Allison powered airplanes.

Today, Vintage V12’s is the world’s leading team of engineers and mechanics breathing life into these planes that saved and changed the world. From complete restorations for museums, airshows and private collections, to championship winning planes at the Reno Air Races, Vintage V12’s offer unparalleled craftsmanship, performance and safety in every engine that goes back into these amazing planes.

WHAT WE DO

Our goal is to restore our customer's engines to meet or exceed the same level of performance, durability and reliability as the original engine.

Our Process

Restoring a vintage aircraft engine involves a number of important steps to ensure it will meet the original manufacturer performance specifications.

Major steps involved in the process are: disassembly, cleaning, inspection, check fits/tolerances, reassembly and final testing. The following information provides an overview of our engine restoration process.
