Cosworth High Performance Short Block Subaru EJ25
Cosworth EJ25 (STI) short block has gone through countless hours of dyno evaluation to determine the best combination of parts to guarantee maximum reliable performance. Each EJ25 short block starts with a brand new Subaru case. The case is inspected and then the bores are honed to perfection to receive Cosworth Forged Pistons. We then balance the rotating assembly that includes a new STI Forged crank and Cosworth Forged H-Beam Connecting Rods to within .5 gram. The select parts are professionally assembled by one of Cosworth’s skilled engine builders using our own coated, tri metal race spec bearings.
Options include:
STI forged crankshaft, Billet timing belt guide. For added performance, please see our Cosworth CNC ported Big Valve Cylinder Heads and high performance camshafts.
