We are in the works with Cosworth to become a distributor of their products!
To start dealing with them directly we need to place a large order so to do that we are looking for preorders on anything Cosworth. Pricing will be determined on how many items we get on our initial order. I promise it will be worth it!
Cosworth celebrated its 45th year at the top of the world motorsport stage in 2003. During that time, Cosworth has established itself as the most successful engine manufacturer in Formula One as well as achieving numerous successes in CART, Indycars and the World Rally Championship.

Subaru EJ25 STI (2.5L) 79mm stroke billet crankshaft
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 failure. Cosworth billet crankshafts are machined from ultra strong EN40B steel and are engineered to endure the harshest conditions and have been tested to withstand over 1000HP! Features include superior lubrication, profiled counterweights and added strength.
Subaru EJ20/EJ25 High Performance Rod Bearing set
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 what drivers expect from high performance Tri-Metal engine bearings. Engineered with the following features: •High strength overlay plate with reduced thickness for better oil control and less friction •Hardened steel backing on all connecting rod bearings •Increased crush and elimination of flash plating •3/4 grooving on Main Bearings providing optimum oil supply •Tight consistent wall tolerances •Oversize chamfers where applicable •Tested to over 1000 horsepower!
Subaru EJ20/EJ25 Camshaft set
Cosworth has been engineering camshafts for nearly 50 years. That coupled with years of innovative multi valve cylinder head design ensures our camshaft designs or the most efficient in providing maximum usable power across the widest power band. Each cam is ground from a new chill cast 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 Subaru EJ25 cams are profiled to increase boost response thereby increasing engine torque and power and are fully compatible with the Subaru STI AVCS. Please download the technical document on the left for camshaft specifications.
Ground from new chill cast billets
Price is for complete set of four
Requires spring upgrade or high performance valve train
Works well with big turbo
Subaru EJ25/EJ20 Forged Piston Set
The piston is one of the most important components within an engine. It can be subjected to directional change up to 285 times every second and must withstand acceleration forces up to 8500g. Cosworth high performance forged pistons are designed and engineered to withstand this type of punishment and still perform. All Cosworth forged pistons are manufactured using the same methods as our Formula One pistons and feature friction reducing skirt coating, ultra strong pins, polished tops and patented anti-detonation bands. Additionally, each application uses a unique forging to minimize weight and ensure the strongest possible piston design. • Proprietary Cosworth alloy • Popular sizes • Unique forging • Skirt coating • Polished top • Anti-detonation bands • High strength pin
Subaru EJ20/EJ25 High Performance Cylinder head Stud Kit
Essential for high performance engine builds, heavy duty head studs reduce cylinder head movement in high boost engines optimizing cylinder head to block sealing. Ultra high performance fasteners are manufactured from high tensile strength steel and come complete with nuts and washers.
Subaru EJ20/EJ25 Billet Timing Belt guide
Replaces the factory sheet metal timing belt guide to help reduce the possibility of the timing belt skipping a tooth during high rpm use. Precision machined from aluminum with a hard anodized finish.
Subaru EJ20/25 Oil Pump
Designed to improve the oiling on modified engines. Each pump is disassembled and inspected. Oil galleys are then honed to ensure unobstructed flow. We then incorporate a modified pressure relief valve to maintain pressure stability throughout the rpm range. Note: Flow rate is unchanged. This is an essential item on any high performance engine.
