Jim Botelho
General Manager
Jim is the General Manager of Danbury Competition Engines (DCE) and nephew of Joe LaPine, the founder of DCE. Jim continues to learn the craft and science of high performance engine building under his uncle and continues the tradition of the company as the business grows due to increased capabilities, increased expertise of staff, and DCE’s good name in the community. Jim holds a Master’s degree in Mechanical Engineering with three decades of design experience. Jim’s most significant accomplishment in the powersport industry includes the ground-up design and development of a high-performance race/street engine for the Harley Davidson aftermarket. This product is at the final stages of development and is planned to soon become part of a new product offering at DCE.
In addition, Jim has developed new products to support the 7.3L Ford Godzilla engine including a new, low profile intake manifold aimed at the Fox-body mustang market and similar applications.

Jeff Roell
He supports current customers – of the combined DCE and DCD – at these races and advises them throughout their race weekend with encouragement, any complimentary quick fixes that are needed and even lining them up in the pits. Jeff has known and worked with Joe Lapine for over 30 years and Jim Botelho for almost 20 years. These relationships and group project efforts through the years resulted in the successful combining of DCE and DCD for a larger, more successful “One Stop Shop” where customers can come to receive great service with integrity and value.
Our History
From racing, to high performance street, to basic engine repair and rebuilding, DCE has supported the Danbury area since 1979. Our roots go back to supporting the Danbury Fair Race arena. Our passion for high performance is still just as strong now and we look forward to helping you on your next project.
