Street/Race Exhaust Camshaft for 1.8T 20V

The Integrated Engineering Street/Race Exhaust Camshaft is engineered for VW/Audi 1.8T 20V engines, specifically the 06A and 058 engine codes. This combination is optimized for mid to larger aftermarket turbo builds targeting 400-600 horsepower, with a powerband extending from 4000 to 8000 RPM. The specialized cam profile and centerline grind are developed to precisely re-tune valve sequencing, ensuring it effectively matches the flow and power curve characteristics of your turbocharger. While increasing performance, the design aims to retain a relatively smooth idle. This exhaust camshaft is compatible with the IECVA2-2 Street/Race Intake Camshaft and the IECVA1-2 Race Intake Camshaft. Technical specifications include 267 degrees of advertised duration, 204 degrees duration at 0.050 inches lift, 0.370 inches of lift, and a 108-degree cam lobe centerline (CLA). The camshaft sprocket is pre-set with a factory-style timing mark for straightforward installation, mirroring the stock camshaft process. Due to the increased powerband and higher RPM limits enabled by larger turbos and camshafts, upgrading valve springs and retainers is highly recommended to handle the added strain on valvetrain components. For optimal valvetrain harmonics, safe revving, and extended cylinder head life, installing an IE 1.8T 20V Valve Spring & Retainer Kit is advised. The factory camshafts are typically tuned for smaller stock turbochargers and low boost pressures, which is not ideal for aftermarket setups that utilize higher boost at higher RPMs. Upgrading to these performance camshafts helps synchronize your valvetrain with your turbo's most efficient range, unlocking significant power gains when properly configured.
