The Impreza GE is the only model in this SUBARU branch to leave the factory with 301hp, and this page gathers what holds its EJ257 bottom end together: the fastener and the shell, not the moving part.
You will find ARP M11x1.25mm head studs, ACL Race Series big end bearings in 52mm and 48mm, and ACL Race Series main bearings in 52mm and 60mm. All are supplied in standard size, in tri-metal, sized for the loads of a built engine.
Forged rods and pistons for this engine are listed under 2.5L 16v - EJ257.
