Tomei Strengthened Timing Belt Subaru WRX EJ20 02-05

Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei???s racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei???s products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei???s attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because of even miniscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.

Although the timing belt is a common part of the engine, not all OEM and aftermarket timing belts are designed to be used on highly tuned turbo powered engines. The durability of the timing belt is greatly reduced with performance engines running at high RPM with aggressive camshafts, increased torque coming from the valve springs, extreme heat conditions from the larger turbos and more. Tomei strengthened timing belts are designed and manufactured with a Kevlar fiber belt surface, H-NB rubber, and the glass cable core for increased tensile strength and durability. This results in a highly durable timing belt that will ensure to keep everything in check even under extreme conditions. Timing belt failure can cause catastrophic engine failure. On and interference engine, a broken timing belt will cause the valve to stay in the open position, which means the piston will contact the valve as it hits top dead center, shattering the valve and destroying the inside of your engine.
