Engine bearings one of most vital components within an engine are often overlooked when considering high performance upgrades. Performance engineered; multi-layer bearings generate less heat than normal bearings by reducing friction. Cosworth Race bearing sets feature a unique combination of design; metallurgy engineering to deliver performance in extreme condits. Cosworth Race bearings setsare available in sizes to accommodate most applications. Size 1 bearings a nominal standard size are used most applications. Size 2 bearings feature an additional .001 clearance should be used
when extra clearance is required.
Key Features
High strength overlay plate with reduced thickness better control less friction
Hardened steel backing on connecting bearings
Increased crush better retention
3/4 grooving on Main Bearings providing optimum supply
Tight consistent wall tolerances
Oversize chamfers where applicable
Flash plating eliminated improved heat transfer
Tested to over 1000 horsepower! Learn More

Cosworth's been engineering camshafts nearly 50 years. That coupled with years of innovative multi valve cylinder head design ensures camshaft designs the most efficient in providing maximum usable power across widest power band. Each is ground from a billet finished using same procedures we in extreme level race engines. Cosworth camshafts the perfect compliment to CNC Ported Valve Cylinder heads. cams profiled to increase boost response thereby increasing engine torque power are fully compatible with CNC Ported Valve Cylinder Heads.

The Cosworth Tumble Generating Valve (TGV) Delete is designed to maximize airflow to your engine by eliminating obstructions inherent to OEM intake ports. TGV deletes made of a fiber reinforced polymer to insulate cylinder head from intake tract; providing your engine with a cooler; denser charge of air. To further increase performance; Cosworth deletes port matched to CNC cylinder heads intake manifold. This product is a direct for 07+ Subaru due to top feed injector design due to a revision to upper bolt pattern of TGV; specifically moving center M6 holes. With manifold top feed injectors; TGV delete will work without issue on most WRX/STI applications. Learn More

The Cosworth Subaru EJ25 CS600 series is designed extreme track use the demanding performance enthusiast. Each assembly is precision built by of Cosworths skilled craftsmen using finest components from parts catalog to ensure maximum reliable power performance. Starting with a Subaru EJ257 semi closed deck block; we meticulously hone each bore to guarantee perfect piston to cylinder wall clearance. block is then assembled with Forged Pistons; motorsport grade Forged H Beam connecting rods along with high performance and main bearings a STI Forged crankshaft. maximum performance; an optional steel billet crank is available (CS600X). Once cylinder block assembly is completed; we install a pair of CNC machine port-bored Valve Cylinder heads with proven S2 camshafts complete with valve lash to specifications. cylinder heads secured with high performance 11mm steel studs sealed with a Cosworth high performance stopper layer steel head gasket. Finally; we install of blue-printed; high pressure pumps maximum lubrication. This proven engine combination been used by teams to events in both North Americaand Europe.

For over 40 years; Cosworth's been leader in innovative multi valve cylinder head design both racing high performance production cars. Cosworth Ported Valve Cylinder head range is latest advancement. Modified from OE cylinder head castings; substantial flow improvements upgraded valve train components offer superior performance your high performance engine.
Each original cylinder head design is carefully evaluated tested to establish improvements required to meet target performance level. Hours of testing flow bench validation used to determine best advanced port design yielding maximum usable power response. However; there is more to cylinder head design than just maximum flow. It is critical that port velocits maintained to ensure drivability valve train components matched to guarantee reliable performance. Once of these factors have been tested validated; final port contour is digitized. Using digitized program; we then reshape both intake exhaust ports using axis mill producing an accurate consistent port shape every time. In addition to reshaping enlarging intake exhaust ports; most Valve Cylinder heads feature a re-shaped combustion chamber to un-shroud valves increasing flow performance. After machining; each cylinder head receives a multiangle high performance valve on precision valve seat cutter. Then each cylinder head is ultrasonically; cleaned; serialized then hand assembled with select high performance valve train components; ready to install on your engine.
