Import Image Racing Stage 1 EJ25 short block is our basic engine upgrade designed to offer more reliability than a stock short block by swapping the brittle cast hyper eutectic pistons with forged replacements. The stock short block can handle quite a bit of power, but it can quickly by ruined by detonation. Each stage 1 block starts as a brand new factory subaru EJ257 short block. It is inspected and the standard cast pistons are removed. The bores are measured and matched with the forged piston replacements ensuring proper clearances are followed. Once the correct pistons are matched to your block, we install them along with new high performance!
