Cosworth goodies now officially available at SpeedLab

Cosworth 2.6L Stroker Kit
Increased displacement means increased performance and the Cosworth 2.6L EJ25 stroker kit is the perfect way to add power and torque to your car. Each kit includes select, matched motorsport grade components ensuring maximum reliable performance. Features billet steel, fully counter weighted crankshaft for smooth, high revving operation along with Cosworth forged steel connecting rods and forged pistons. The Cosworth EJ25 2.6L stroker kit combines the perfect bore to stroke ratio, yielding potentially big gains in torque while still allowing the engine to rotate and produce power in the higher rpm range.

Cosworth EJ25 Forged Piston Set
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 8500g. 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 anti scuff skirt coating, ulta-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 design

Cosworth Piston Rings
High performance piston ring set for Cosworth pistons, EJ25 and EJ20

Cosworth H Beam Forged Connecting Rods
The connecting rod is the vital link between the piston and power. When engine output is increased, the demands placed on the connecting rod increase as well. To ensure engine reliability in all conditions, original connecting rods should be replaced with heavy duty specification parts. Cosworth Forged Connecting Rods are manufactured from high strength 4340 (EN24) steel and machined to precise tolerances.

Cosworth High Performance Head Gaskets
Cosworth High Performance Head Gaskets are engineered to seal in power under the most demanding conditions. Constructed from stainless steel with a folded stopper layer, each application features superior sealing compared to conventional multi layer steel gaskets. Additionally, Cosworth High Performance Head Gaskets are manufactured from pre-coated die cut stainless steel resulting in uniform coating distribution and consistent shape. Subaru gaskets are sold individually. Order two for a complete set.

Cosworth High Performance Bearings
Engine bearings are one of the most vital components within an engine and 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 and engineering to deliver performance in extreme conditions. Cosworth Race bearings sets are available in three sizes to accommodate most applications.

Size 0 bearings have .001" less oil clearance than factory
Size 1 bearings are a nominal standard size and are used for most applications.
Size 2 bearings feature an additional .001" more oil clearance than factory

Cosworth Head Studs
Essential for high performance engine builds, heavy duty head studs reduce cylinder head movement in high boost or high compression engines optimizing cylinder head to block sealing. Cosworth Ultra High Performance Head Studs are manufactured from H11 tool steel with 260,000psi tensile strength and come complete with nuts and washers. Manufactured with hex broach end for ease of installation.

Cosworth Kevlar High Performance Timing Belts
Cosworth Kevlar High Performance Timing belts are 300% stronger than original equipment timing belts and are the perfect compliment when installing Cosworth camshafts or cylinder heads.

Subaru High Volume Air Intake Manifold
The Cosworth Subaru High Volume Inlet Manifold is cast from aluminum featuring large tapered runners with radiused inlets for improved air flow. Plenum volume has been substantially increased and tuned for power. Engineered for easy installation and is the key to making big power. The Cosworth EJ257 plenum is designed for use with the 2004-2009 STI engines equipped with electronic throttle control. The plenum is not designed for use with any cable-actuated throttle body EJ20/25 applications. This plenum is designed to replace the factory Subaru plenum in vehicles equipped with an aftermarket front-mounted intercooler (FMIC) kit. Throttle body position remains stock, ensuring fitment with any brand FMIC kit designed for the stock throttle body and intake manifold.

Cosworth Timing Belt Guide
The original sheet metal timing belt guide can flex from belt deflection when subjected to extreme
rpms causing the timing belt to skip one or more teeth on the crankshaft sprocket. The Cosworth Billet Timing Belt Guide was developed to control this problem and is machined from solid aluminum with a hard anodized finish. Includes mounting hardware.

Blueprinted Oil Pump-W/ high pressure mod .& install kit
High performance engines require additional oil pressure because of the increased demand placed upon various components within the engine. The Cosworth High Pressure Subaru EJ20/EJ25 series oil pump is modified to increase oil pressure helping to ensure superior lubrication. Each pump is carefully inspected and de-burred for unobstructed oil flow. Perfect for high performance daily use Each kit includes all required mounting hardware and seals.

High Volume/Pressure Blueprinted Oil Pump & install kit
Increasing oil volume will help to prevent bearing damage and engine failure. Additionally, sustained High RPM use may cause oil starvation at the rod and main bearings The Cosworth High Volume Subaru EJ20/EJ25 series oil pump utilizes a completely new inner and outer 12mm rotor to increase volume by 20%. Suggested applications include drag, track day and race use. Each kit includes all required mounting hardware and seals

Cosworth High RPM Valve Springs
Cosworth High RPM Valve Springs are the result of countless hours of engineering, testing and validation ensuring the best possible spring for high performance applications. Cosworth High RPM Valve Springs are wound from the world's finest Japanese Kobe steel and feature dual chamfered ends to reduce wear on seats and retainers. Each spring has been engineered with increased seat pressure along with higher lift capability for optimum performance potential and improved valve control. Single spring design allows easy installation with no machining required and is perfect for typical high performance use.

Ultra-High RPM Dual Valve Spring / Titanium Retainer set
Cosworth Ultra Race Valve Spring Kits are engineered for use in situations that require valve control in extreme conditions. Each kit consists of dual valve springs with matched lightweight titanium retainers, keepers, and hardened steel springs seats. Cosworth Ultra Race Valve Springs are wound from the highest quality chrome silicone steel with chamfered ends and are heat treated and stress relieved for long term reliability. Ultra Race Valve Spring kits are compatible with Cosworth high performance valves.

Camshaft set, 2008+ Subaru STI
Cosworth has been engineering camshafts for nearly 50 years. That coupled with years of innovative multi valve cylinder head design ensures our camshaft designs are the most efficient in providing maximum usable power across the widest power band. Each cam is ground from a new billet and finished using the same procedures we use in our extreme level race engines. Cosworth camshafts are the perfect compliment to our CNC Ported Big Valve Cylinder heads. Our cams are profiled to increase boost response thereby increasing engine torque and power and are fully compatible with our CNC Ported Big Valve Cylinder Heads. Sold in a matched set of four camshafts.
