The IAG Performance / Crest CNC Billet Aluminum EJ25 Case Halves are the same premium-grade case halves used in our cutting-edge Stage X Billet Short Block, which has revolutionized the Subaru performance tuning market by reinventing the EJ and addressing virtually every weakness that exists in max-power builds. The EJ25 Case Halves are engineered to eliminate case flex in high-power EJ builds, making it possible to reliably run at a power output rating of 1150+BHP. With features like radiused coolant and oil galleries to improve flow, a 4-bolt bottom end for added strength, and replaceable iron sleeves that make rebuilds easier, these case halves offer a rock-solid foundation to build upon. The IAG Performance / Crest CNC Billet Aluminum EJ25 Case Halves are machined by Crest CNC (formerly Willall), renowned for their precision-machined billet aluminum engine blocks and components. With Crest’s proven track record of producing blocks that endure the rigors of high-output engines, these case halves provide an unbeatable foundation for those pushing the limits of performance.
