Type: STEP1 Duration: IN 248° Valve Lift: 8.6mm Valve Timing: 90°-120° For BNR32 BCNR33 BNR34, RB26DETT, MY08/1989-08/2002 Remarks: With "VALCON type RB26". Maximum variance 30°,compatible with stock pistons. *Cylinder head facing or thin head gasket could cause contact with valve and piston. For BNR32, BCNR33, BNR34, Engine RB26DETT, MY08/1989-08/2002 Features: - The intake cam side of the RB26DETT is changed to allow variable valve timing. The cam has duration of 248° which seem a little conservative. However, with the variable timing, power increases can be found at low or high RPM - Whether you are looking to find some time on the circuit through improve acceleration out of lower speed corners, or simply want something which can overtake with ease on the street, the HKS V Cam System provides good power from low RPM reducing the necessity for excessive gear changes. This especially noticeable when going from vacuum to boost to give the feeling of increased displacement. - Improved valve timing will allow for more complete combustion leading to improved fuel efficiency and cleaner exhaust emissions. - HKS V CAM System is compatible with the stock pistons. (When using with the thinner head gaskets or modified cylinder head, the clearance between valve and piston may be insufficient.) - Exhaust Cam should be selected dependant on turbo choice.(Recommended: GT-SS-256°, GT2530-264°)

Type: STEP2 Duration: IN 264° Valve Lift: 8.7mm Valve Timing: 75°-125° Remarks: With "VALCON type RB26". Variance 50°, HKS Forged Pistons Required. For BNR32, BCNR33, BNR34, Engine RB26DETT, MY08/1989-08/2002 Features: - Specially designed cam for Step 2 has duration of 264°, valve lift 8.7mm. Acceleration at high rpm is smoother than solid Step 1 camshaft (272IN-272EX). Step 2 is suited to higher power output at all range of engine rpm. - Strength is enhanced when used with upgraded Valve Springs at high RPM (recommended limit 8500rpm). - Engine output and torque are substantially improved at all engine RPM range compared to solid Step 1 (272IN/EX). Step 2 was designed to show significant power and torque improvement for vehicles tuned to output 600ps or higher compared to old type Step 1 type B (256EX).
