Do you have a sport compact that has a big turbo on it and it makes all of the horsepower? You can have one too and you should sleeve it using a set of Darton Sleeves. Some engines depending on what unit have inherent weak factory sleeves. Darton’s design and engineering has produced sleeves that are much stronger and can hold the power you push through your motor. Utilized by several drag racing teams as well as teams racing in the time attack circuit, you too can obtain a set of Darton sleeves for your build.
