Product Information
Cosworth Long Block Big Valve Cylinder Heads KK3920 Camshafts 79mm Billet Crankshaft 9.2:1 CR Subaru EJ25 2.5L 04-06

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 Cosworth's 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, we meticulously hone each bore to guarantee perfect piston to cylinder wall clearance. The block is then assembled with Cosworth´è_s Forged Pistons, motor sport grade Forged H Beam connecting rods along with high performance rod and main bearings and a new STI Forged crankshaft. For maximum performance, an optional steel billet crank is available (CS600X). Once the cylinder block assembly is completed, they install a pair of CNC machine port-bored Big Valve Cylinder heads with their proven S2 camshafts complete with valve lash set to our specifications. The cylinder heads are secured with high performance 11mm steel studs and sealed with multi layer steel head gaskets. Finally, Cosworth installs 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.

    TEXT_OF_5_STARS by David
    "1. Product already arrived and in good condition long before this survey showed up in my email. 2. Initial online order attempt failed. Tried again about 2 weeks later and it worked fine.3. Craftsmanship was a bit lacking as the sway bar (rear) end was apprx 1/4" higher on one end then the other. However it did make a noticeable improvement in the handling of my Miata."
