The Cosworth ECPro is a higher performance solution for engine management and available now for the 2008 and newer Subaru STI . Engineered in conjunction with Pectel Control Systems, the Cosworth ECPro features an OEM compatible harness connector and a full base calibration allowing you to go straight to the dyno without the workload of full ECU and vehicle configuration. The Cosworth ECPro is perfect for demanding applications such as track day, rally and motorsport use and is housed in a machined from solid aluminum case with professional motorsport specification electronics.

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 engine response and torque and are fully compatible with our CNC Ported Big Valve Cylinder Heads. Sold in a matched set of four camshafts.

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 a hex broach end for ease of installation. Additionally, genuine Cosworth head studs utilize a base seating feature to evenly distribute maximum load on the stud and not the threads. This feature is typically found only in high level race engines. This is the ultimate head stud for serious SR20 applications

Front mounted intercoolers offer improved performance potential for Subaru applications. The Cosworth front mounted intercooler system for the 2008 - 2009 Subaru STI replaces the restrictive, heat-soak prone original top mounted core. The engineered system features an efficient large aluminum core with mandrel bent aluminum tubing for maximum performance up to and exceeding 600hp.The intercooler core is rubber mounted on a secure bracket system to help eliminate cracking and breakage. Installation is simplified as no cutting of vehicle is required.

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.

We are pleased to announce the release and availability of our front mount intercooler system for the 2008-2009 Subaru STI (GRB). This bolt on system installs without any cutting or trimming of the vehicle and features large diameter powder coated aluminum tubing and a robust isolated mounting system. Replacing the heat-soak prone top mounted original intercooler increases the potential for performance by providing cooler charge air for the engine. The engineered system features a large, efficient aluminum core with mandrel bent aluminum tubing for maximum performance up to and exceeding 600hp.

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, factory Subaru crankshaft 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.
