After several years of testing and development, the Cosworth CS600 series High Performance Subaru EJ25 long block has arrived. The CS600 series is designed for extreme track day use and the demanding performance enthusiast. Each assembly is precision built by one of Cosworths skilled craftsmen using the finest components from their parts catalog to ensure maximum reliable power and performance.

Starting with a new Subaru EJ257 semi closed deck block, Cosworth meticulously hones each bore to guarantee perfect piston to cylinder wall clearance. The block is then assembled with their Forged Pistons, motorsport grade Forged H-Beam connecting rods along with their high performance rod and main bearings and a new STI Forged crankshaft.

Once the cylinder block assembly is completed, Cosworth installs a pair of their CNC machine port-bored Big Valve Cylinder heads with proven "S2" camshafts complete with valve lash set to their specifications. The cylinder heads are secured with high performance 11mm steel studs and sealed with multi layer steel head gaskets.

Finally, they install one of their blue-printed, high pressure oil pumps for maximum lubrication. This proven engine combination has been used by top teams to win events in both North America and Europe and is available now for general sale.
