The IECVA2-1 Street/Race Exhaust Camshaft features a more aggressive cam profile and centerline grind. When combined with an IE intake camshaft, the combination is perfect for mid to larger-sized aftermarket turbo builds in the 400-600 horsepower range with an ideal powerband of 4000RPM-8000RPM.
This exhaust camshaft is designed to be installed along with a matching IE intake camshaft. Depending on your turbocharger, this cam can be used with either our street/race or race intake camshafts. The specialized cam profile and centerline are engineered to re-tune the sequencing of the valves to match the flow and power curve of your turbocharger while retaining a relatively smooth idle.
Compatible Exhaust Camshafts:
This camshaft has been designed specifically for the 1.8T 20V (06A & 058) engines and engineered for easy installation. The cam sprocket is pre-set for optimal performance and features a factory-style timing mark that follows the exact same installation process as a stock camshaft.
Larger turbos and camshafts allow for a larger powerband and higher RPM limits putting more strain on the valvetrain components. Upgrading the valve springs and retainers to match is highly recommended. For the best results in optimum valvetrain harmonics, safe revving, and long cylinder head life install your new camshaft along with an IE 1.8T 20V Valve Spring & Retainer Kit.
The factory-equipped camshafts in your VW/Audi 1.8T 20V engine are tuned for the small stock turbocharger. Stock cams are designed for low boost pressures in low RPM ranges, which is at odds with aftermarket larger turbos that run higher boost pressures at higher RPMs. Matching the valve lift to the turbo's most efficient range with camshafts sequences your valvetrain to your turbo and unlocks instant power gains when setup correctly.
