Description
IAG / Crest Stage X Billet Aluminum EJ25 Subarushort Block Using the same world-leading technology found in Willall's incredible billet GT-R block, the billet EJ case seeks to change the Subaru performance tuning market by reinventing the EJ and addressing virtually every weakness that exists in max-power builds. The Stage "X" Block is a complete short block built on the Willall billet platform, which also includes pistons, rods, bearings, crank, bore/hone, case bolts, line hone, and final assembly and blueprinting. Stage X Billet EJ25 Case Features: Machined from solid billet 6061-T6 Aerospace grade aluminum Darton Ductile iron sleeves Increased material thickness in all known weak points (around head studs, bottom end location) Unique 4 bolt bottom end strengthening Threads are rolled into the block rather than conventionally cut for much greater strength Full cooling system operation Radiused coolant and oil galleries for improved flow and less foaming/turbulence Fits all factory engine bay ancillaries (i.e. AC/PS/etc.) Multiple Times stiffer and stronger than the stock case Precision machined for a superior surface finish Hard anodized to avoid marking or straining
