anyone fitted one of these yet ?


HKS VALCON Plus V CAM KIT Pro FAIRLADY Z (Z33)

"Camshaft + Valcon Pro Kit will improve power output at high rpm that is a weak point of VQ35DE.
Not only high rpm but low and middle rpm range will be also improved by valve timing control with Valcon Pro.
It can be used for normal aspirated and forced induction engines.
Reinforced Valve Spring is not required."


"Although stock VTC has a ability to work for 40 degree, the stock valve timing map has data only for 90°- 125° that means it works only for 35°.
HKS VALCON controls for 40°.
Maximum RPM : 7500rpm (Stock rev limit is 6600rpm. To increase RPM limit, con’rod needs to be upgraded.)"

"After installation, re-setting of valve timing, fuel and ignition controls are required. As VQ35DE does not have shim, lifters need to be replaced to adjust valve clearance.
It cannot be used for 35th Anniversary model and Late Model as they have VTC for exhaust camshafts."
