HKS V-Cam Step 2 RB26DETT

Variable Valve Timing System allows the classic RB26 to become a new generation engine. ""V CAM SYSTEM"" & ""VALCON type RB26"" are combined as an affordable set!

STEP 2

Features:

Specially designed cam for Step 2 has a duration of 264 °, valve lift 8.7mm. Acceleration at a 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).

Precautions for Use

Maximum RPMSTEP 1 - 8,000rpm (Stock Rev Limiter)
STEP 2 - 8,000rpm (With Stock Valve Springs)
8,500rpm (With HKS Valve springs, Sold separately)
STEP Pro - 8,800rpm (With HKS Valve springs, Sold separately)Oil Temperature, Water TemperatureIf oil viscosity is low, oil pressure may not reach adequate levels resulting in valve timing not reaching desired values. Valve timing will not increase when water temperature is under 60 °CRecommended OilSUPER OIL (RB), Racing Pro Oil 10W-50Timing BeltCheck every 10,000km for wear and tension. Adjust or replace if necessary.
