GSC Power-Division Billet S3 Camshafts Subaru EJ257 Dual AVCS (STI 2008+) 282/282

GSC Power-Division Billet S3 Camshafts - Subaru EJ257 Dual AVCS (STI 2008+) - 282/282 - Complete Set

GSC Power-Division billet S3 camshafts for the 2008+ Subaru WRX STI EJ257 with dual AVCS. Built for high horsepower cars with a power range of 750–1000 WHP and a rev range of 4,500–9,500 RPM, the S3 is GSC's most aggressive grind for the dual AVCS EJ257.

This listing covers the complete set of four camshafts (left and right intake and exhaust). To use their full potential these cams need a built bottom end (sleeved or closed deck recommended), built and ported heads with the casting clearanced for the higher lift, and upgraded valve springs. A standalone ECU or speed density tune is highly recommended for proper idle characteristics.

Note: Check the product images for cam placement — long nose = left side, short nose = right side. Due to the lobe size, head castings will need to be machined slightly for clearance; check during installation. Proper break-in and high zinc oil are a must on flat tappet engines. Must be installed by an experienced engine builder.
