Tomei Poncam Type-B Cams Camshaft for Nissan Skyline GTR RB26 R32 R33 R34
Type A Designed to best suit the stock & N1 turbos for optimum performance balance of low to mid range torque. The Exhaust cams duration was reduced to maintain best idling. Type B By extending the duration timing compared to the Type A Poncams, both response and peak power was raised and these camshafts best compliment the mid to large size turbo charged applications.
Cold Valve Clearance mm±0.01. Sports Catalytic Converter or Straight Pipe. Stock or Larger Bolt On Type.
N1 or Full Turbo Kit Upgrade. TYPE R for Stock Cat. Equiped Cars The Type R camshafts were designed due to popular demand from end users who are looking at upgrading the performance potential of their GTR while staying within the limits of recent street legal requirements. Recent laws on emissions and exhaust noise was made stricter in Japan so to have a quieter car by running smaller exhaust systems raises the exhaust back pressure which greatly reduces the response and hinder performance.
Our engineers then designed these Type R camshafts to suit the needs of those who need to keep such setup and benefit with performance gains. To improve performance gains on cars running catalytic converters. To maximise the stock turbos performance potential. To reduce the exhaust back pressure.
Improves overall throttle response and torque. To protect the stock turbos performance limits and minimise turbo failure. Back Pressure for Stock Cat. J-ING Test car setup during acceleration (in 4th gear from 2,000rpm to 8,000rpm). Peak Power Comparison for Stock Cat.
The peak power output is less than the Type A & Type B camshafts but the response is better with the Type R camshafts.
