The Subaru Spec-R Short Block engine build is designed to optimize the performance of the factory engine while maintaining exceptional reliability. Utilzing lighter and stronger forged aftermarket parts the engine receives the same attention that a race prepared engine would. While this is a basic package any amount of other upgrades can be added for an additional charge, including but not limited to Pro lightened cranks, Pro Piston Polish Service as well as a wide variety or coatings and treatments to further improve longevity and HP. Add a PURE Tuning Cylinder head stage and have a full long block built. The Spec-R short block comes with a complete build sheet, break-in-procedure, recomened oil and serial number.
