High Pressure Pump
High performance engines require additional pressure because of increased demand placed upon various components within engine. Cosworth High Pressure Subaru EJ20/EJ25 series pump is modified to increase pressure helping to ensure superior lubrication. Each pump is carefully inspected deburred unobstructed flow. Perfect high performance daily Each includes required mounting hardware seals.
High Volume Pump
Increasing volume will help to prevent bearing damage engine failure. Additionally; sustained High use cause starvation at rod main bearings Cosworth High Volume Subaru EJ20/EJ25 series pump utilizes a completely inner outer 12mm rotor to increase volume by 20%. Suggested applications include drag; track and race use. Each includes required mounting hardware seals. 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.
Key Features

The Cosworth Subaru High Volume Inlet Manifold is cast from aluminum featuring large tapered runners with radiused inlets improved flow. Plenum volume been substantially increased tuned power. Engineered easy installation is key to making power. Cosworth EJ257 plenum is designed use with 2004-2009 engines equipped with electronic throttle control. plenum is designed use with cable-actuated throttle body EJ20/25 applications. This plenum is designed to replace factory Subaru plenum in vehicles equipped with an aftermarket front-mounted intercooler (FMIC) kit. Throttle body position remains stock; ensuring fitment with brand FMIC kitsigned the stock throttle body intake manifold. 2008-2009 Subaru STIs Cosworth FMIC (p/n 20005378) is highly recommended.
Features

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.
