    I see you changed the solenoid pic, makes it clearer. So the s15 one doesnt have the NRV, but it looks like it has larger oil ways. I cant see the oilways in the solenoid alone makng any difference though, considering that the system is active pretty much all the time you are driving the car normally.

    Maybe how fast the sprocket wears is directly related to the amount of time spent over 5700rpm (the shut-off point) ie drifters wear out sprockets much faster than regular drivers! I cant see there being much wear at idle cos after all, there is hardly any load on the engine. But there is a lot of force on the whole valvetrain with high revs and boost.

    Thanks for the info on solenoids though!
