The campaign, "The Castrol Syntec Top Shop Challenge" pits seven custom car and after-market automotive shops against each other to create the highest-horsepower engine from scratch. Each shop participating in the contest was chosen by the editorial teams of the SIM titles, like Lowrider, Eurotuner, Import Tuner and Super Street.
Consumers who go to SyntecTopShopChallenge.com can vote for their favorite engine and enter the official sweepstakes to win the top engine. --Karl Greenberg
