Stage X Cosworth Timing Belt & Alloy Camshaft Pulley Upgrade Kit 99-02MY EJ20/22/25

This kit combines a timing belt kit with an alloy camshaft pulley upgrade. The timing belt kit uses exactly the same components the car had when it left the production line, plus the Cosworth Kevlar timing belt. Cosworth belts are designed to withstand the stress and heat of high-horsepower or high-revving engines and are 300% stronger than the original equipment, which makes them a popular choice for modified Subarus.

A weak area on Subaru EJ series engines is the plastic Bakelite camshaft drive pulleys. Over time they become brittle and eventually fail, causing catastrophic failure and internal engine damage. The Stage X alloy camshaft pulleys included in this kit are manufactured from aluminium.

Fits 2002MY+ EJ20/22/25 engines.

For more extreme power levels and applications, a Motorsport tensioner upgrade with increased load actuation is also available for this kit.
