Description   Back to AMS Performance Main Page AMS Performance Stage 1 600hp Short block Subaru EJ257 The AMS Performance Subaru STI Stage 1 EJ25 Short Block is the ultimate solution for high horse power reliability. Only the best off the shelf and custom designed AMS spec components are used. Combine that with the latest in machine and assembly practices and you are assured only the best! All AMS race engines are individually handcrafted at AMS using the same care as the ones found in their world record holding street and race cars. When you choose an AMS engine you are investing in the knowledge gained from assembling 1000's of race engines over the past 10+ years. With over 200 Victories in Motorsports over the last 3 years alone, it is clear that AMS is the only choice for your car! Just like our 1500 HP Alpha GT-R's and 1400 HP AMS Drag EVO, every motor is balanced, blueprinted and assembled to AMS’ exacting standards. Before assembly each block is checked for correct dimensions, cylinder bore, mains, block flatness, etc… to ensure you get the best foundation for your new engine. Every engine we assemble has a build sheet where tolerances, torque specs, and clearances are documented. Features Recommended for applications up to 600hp JE Pistons Manley H-beam Rods Brand new short block High performance rod & main bearings Precision AMS spec machine work on block & crank Precise, documented hand assembly
