Using the same world-leading technology found in Willalls 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.
The IAG / Willall Stage X Short Block has a power output rating of 1100+BHP.
BUILD TIME ON ALL BLOCKS IS 6-8 WEEKS.
