Big Valve Cylinder Heads For over 40 years, Cosworth has been the leader in innovative multi-valve cylinder head design for both racing and high performance production cars. The Cosworth CNC Ported Big Valve Cylinder head range is the latest advancement. Modified from new OE cylinder head castings, substantial gas flow improvements and upgraded valve train components offer superior performance for your high performance engine. Each original cylinder head design is carefully evaluated and tested to establish the improvements required to meet the target performance level. Hours of testing and flow bench validation are used to determine the best advanced port design yielding maximum usable power and response. However, there is more to cylinder head design than just maximum flow. It is critical that port velocity is maintained to ensure drivability and valve train components are matched to guarantee reliable performance. Once all of these factors have been tested and validated, the final port contour is digitized. Using the digitized program, we then reshape both intake and exhaust ports using a 5 axis CNC mill producing an accurate and consistent port shape every time. In addition to re-shaping and enlarging the intake and exhaust ports, most Big Valve Cylinder heads feature a re-shaped combustion chamber to

High Performance Short Block Assemblies Cosworth high performance engine assemblies are the perfect basis for your high performance application. Each version has gone through countless hours of engineering and evaluation to determine the best combination of parts and build specification, ensuring maximum reliable performance. Each Cosworth high performance engine assembly starts with all new select components as the foundation of the performance build. Every block is thoroughly inspected before the cylinders are honed to perfection. We then balance the rotating assembly that includes either a new factory forged crankshaft or Cosworth billet crank along with Cosworth forged connecting rods, Cosworth tri-metal bearings and Cosworth forged pistons. The motorsport grade parts are then professionally assembled by expert engine builders in the Cosworth engine assembly facility. Each high performance engine assembly includes a complete specification sheet listing all critical dimensions along with a serialized plaque. For maximum performance, combine with a Cosworth CNC ported Big Valve Cylinder Head and camshaft set.

Billet Crankshafts Increased engine performance often means increased engine speed and load. Original factory crankshafts may not be able to withstand the added stress, resulting in catastrophic engine failure. Additionally, many OE crankshafts rod journals are lubricated from only one main oil feed. Cosworth billet crankshafts feature full-flow oiling whereby each rod journal is lubricated from two main sources. This provides superior lubrication during sustained high rpm use preventing rod bearing failure. Cosworth Subaru crankshafts are manufactured entirely from high grade steel in a light-weight, high strength design with a unique Isotropic Superfinish.

the need for replacement. By creating a smooth and shiny finish, the ISF Process improves the life and efficiency of moving metal parts. Increased life translates into lower operating costs as well as better performance. In extreme environments, such as automobile or motorcycle racing, every component must work in harmony at 100% capacity. Races are won and
lost by fractions of a second, so it all comes down to getting the most power output possible. With the ISF Process, the energy normally lost to friction is now available in the form of increased power output. Once friction is reduced, the engine will run cooler allowing for longer durability of parts and fewer failures.

Forged Pistons With 50 years of world class engine design and manufacturing experience, Cosworth’s intimate knowledge of the interaction between the piston and other engine components gives the us the distinct advantage in piston design resulting in the finest piston available. The piston is one of the most important components within the engine. It can be subjected to directional change up to 285 times every second and must withstand acceleration forces of 8,500 Gs. Cosworth high performance forged pistons are designed and engineered to withstand this type of punishment and still perform. All Cosworth pistons are manufactured using the same methods as our Formula One pistons and include features such as anti-scuff skirt coating, ultra-strong pins, polished top and patented anti-detonation bands. Additionally, each application uses a unique forging to minimize weight and ensure the strongest possible piston.
Features & Benefits: ■■ ■■ ■■ ■■
Skirt profile & oval technology - reduces engine noise, increases life & performance F1 quality forgings - proprietary CosAl 010 for high stress applications Oil and combustion gas control features - reduced blow-by and oil consumption Offset pin bores - for reduced engine noise

Cosworth Tech: Green Pistons Xylan is a fluoropolymer coating designed for use on various engine components and fasteners. Cosworth pistons use xylan coating to provide lubrication and control friction, wear resistance, heat resistance, nonstick and release properties and, at the same time, can also protect from corrosion. This is the same coating we use on many of our ultra-high performance race engines.
Spare Piston Pins and Circlips Cosworth Pistons feature heavy duty, ultra strong piston pins designed for the higher stress and elevated load levels found in high performance engines. Spare parts are available for routine engine rebuilds. For ease of circlip installation on Subaru engines, we offer an exclusive installation tool engineered to simplify the task. This high quality tool is machined from steel to ensure years of trouble free use.

Thermal Composite Gaskets The Cosworth Thermal Guard Composite Intake Gasket is designed to aid in the reduction of inlet air temperature by isolating the intake manifold from the heat generated by the engine’s cylinder head. By reducing the temperature of the inlet manifold the temperature of the intake air charge is also reduced. The density of cooler air is greater than that of warm air. A denser intake air charge contains more oxygen which results in the potential for increased power and torque. Each Cosworth Thermal Guard Composite Intake Gasket is precision manufactured from an engineering grade composite phenolic material that resists deformation common with plastic gaskets. As an added feature Cosworth Thermal Guard Composite Intake Gaskets are reusable and include a tube of “Hylomar Universal Blue Racing Formula” sealant. The use of OE inlet manifold gaskets is not required with the Cosworth Thermal Guard Composite Intake Gasket.

Oil Control High performance engines reject a substantial amount of heat through the oil system. Maintaining oil pressure and control along with an increase in actual volume will help dissipate heat and stabilize oil temperatures. Cosworth oil control components are engineered to combat several problem areas experienced in high performance engines. Mitsubishi 4G63 Crankscraper The Cosworth 4G63 Crankscraper is engineered to reduce parasitic drag on the crankshaft caused by oil accumulation that surrounds the crankshaft during rotation. This oil buildup causes additional drag and can reduce power output. Additionally, overall oil control is improved by keeping oil in the sump. Especially useful in high rpm and race applications. Mounts to main bearing girdle. Designed from 2.6 mm (12gauge) steel plate and includes required mounting hardware.

Nissan Oil Control Baffle The Cosworth Oil Control Baffle for the Nissan VQ35 has been engineered to stop oil from surging away from the oil pick up during hard driving conditions. The unique Cosworth one-way control valves allow oil to flow towards the pickup but restrict oil from migrating to the back of the sump during aggressive maneuvers to help maintain constant oil pressure. Manufactured from stainless steel. Model Year 2003-2004 require fit kit PN 20008632 for proper installation.
Subaru Oil Pan Baffle Oil control can be a problem with high performance and high revving Subaru engines. High crankcase pressure along with the horizontal engine platform restricts rapid oil return from the cylinder heads to the oil pan. Pressure builds in the heads and crankcase causing massive blow by and power loss. The Cosworth Subaru Oil Pan Baffle has been engineered with diverters to control oil returning from the cylinder heads to the pan directing it away from the crankshaft. Additionally, oneway valves prevent oil from re-entering the upper crankcase chamber thereby limiting blow by and preventing oil starvation during hard driving. Manufactured from stainless steel and installs easily between the block and oil pan on both EJ20/EJ25 series engines. Use with our High Volume Oil Pan for maximum oil control.

Subaru Dry Sump - 20004463 The Cosworth Dry Sump Setup Kit for the Subaru EJ series engine is a must for race and performance applications. Dry sump oiling systems offer an unparalleled level of safety and reliability compared to factory wet sump systems. Complete crankcase oil scavenging reduces excessive and residual oil that can cause blow-by and power loss. A dry sump also offers more consistent oil pressure to the engine,
improved scavenging, and increased ring seal due to greater pan vacuum. The Cosworth Dry Sump System for the Subaru EJ20/EJ25 replaces the original oil sump with a machined from solid, low profile alloy pan with twin scavenge ports, internal baffling and o-ring sealing. A two stage scavenge pump driven by a HTD belt, mounted to a heavy duty bracket evacuates the oil from the engine.

Brake Pads The racing performance pedigree that is so much part of Cosworth’s heritage, is clearly demonstrated in this exciting addition of brake pads to our Aftermarket Performance Parts range. With two grades of friction material, the StreetMaster and TrackMaster ranges deliver exceptional levels of stopping power specifically tailored for fast road and track applications respectively. Manufactured in the United Kingdom, Cosworth brake pads feature a 1.5mm granulated interlayer which not only serves to act as a shock absorber, helping to reduce stress on the rotor surface but triples bonding strength so diminishing edge lifting. To reduce the “bedding-in” or “seatingin” time - this is the time it takes for the pad and disc to adapt to each other - all Cosworth brake pads are heat seared. This process heats the friction material to in excess of 600°C “toasting” the surface greatly enhancing the performance the first time that the driver applies the brakes. Scorching pads also significantly reduces initial fading. Fading increases the necessary force and pressure required to maintain the deceleration of the vehicle. Cosworth’s brake pads range offer exceptional performance with no compromise. Why choose Cosworth Brake Pads? ■■
