Remark: - Valves and pistons may not clear when V Cam System is used in conjunction with thin head gasket or modified cylinder head. - Exhaust Camshaft (Sold Separately) should be chosen depending on turbo choice. (Recommendations: GT-SS = 256 degree, GT2530 = 264 degree) - Vehicle Specific F-CON Harness Sold Separately - Oil pressure cannot be maintained at a safe operating pressure when oil viscosity is low. Valve timing may not reach desired figures due to this. - Camshaft will not advance is water temperature is below 20 degrees Celsius - HKS Step 2 Valve Springs are required - Modification of Cylinder Head necessary for camshaft clearance
