pretty sure both cams have cam phasers... the VQ35DE "revup" and the VQ35HR did...

Yes thats true those motors did have exhaust phasing. But VHR isn't those motors. It's all in the service manual, and can also be seen if look at a disassembled VHR head.

Notice how the intake valve open and close times have a wide range, and the exhaust valve has 0 range?
No clue why nissan did it this way, maybe they couldn't make it all fit in there with VVEL + exhaust phasing, maybe they are saving it so they can have more power in the next generation engine, maybe cost, who knows.
