Not sure if this is an old subject or not. I also have a nissan pulsar with sr16ve (nissans neo VVL engine - like vtec) might be something to look into, has the vq35de for 350z listed. however i dont know squat about this sorta thing.

Might not wanna do it then

 

Well I was able to find this with a few minutes of searching.

"GReddy V-Manage

The V-Manage allows tuning of variable valve timing in older Honda VTEC applications where timing adjustments are "on-off" scenarios initiated by a solenoid or the newer generation iVTEC, Toyota VVTi and VVTLi, Mitsubishi's MIVEC and Nissan's CVTC that control the valve timing using a freer, progressive-rate strategy. The V-Manage not only adjusts the crossover point or VTEC threshold but it can tune the amount of retard throughout the rev range. The unit uses e-Manage Ultimate software and interfaces easily with an e-Mange Ultimate computer to make seamless corresponding fuel adjustments. Also the unit has an auto-learn feature to determine the engine's baseline cam timing scheme and DIP switches that allow the user to quickly switch between stock timing and programmed timing."


And heres some more info from greddy

The SRxxVE engines don't have variable cam settings like the VQ35s do. The SRs just have a High/Low cam setting that IIRC can be setup to use an RPM switch. A VAFC2 would be a pretty good tuning tool for a SRxxVE.
