  5. Cosworth High Performance Engine Bearings for Subaru Baja Turbo 2004-2006
    $114.00
    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

  6. Cosworth Trackmaster Brake Pads for Subaru Impreza WRX TR 2006-2007
    $110.00
    Manufactured in UK; Cosworth brake pads feature a 1.5mm granulated inter-layer which only serves to as a shock absorber; helping to reduce stress on rotor surface triples bonding strength; diminishing edge lifting. To reduce bedding-in or seating-in time - this is time it takes the and disc to adapt to each other - Cosworth brake pads heat seared. This process heats friction material to in excess of degrees toasting surface ; greatly enhancing performance first time that driver applies brakes. Scorching pads also significantly reduces initial fading - fading increases necessary force pressure required to maintain deceleration of vehicle. Cosworth's brake range offers exceptional performance without compromise. Learn More

  10. Cosworth Big Valve Cylinder Heads for Subaru Impreza WRX STI 2004-2006
    $4,240.00
    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.
