That is the VCT solenoid

[Modb]

is it important?

[whiteboy87]

yes. running the rb25det ecu and vct make the midrange way better.

[Modb]

It's explained in this link, how different VVT settings affect's powerband (scroll down until see "Making a good use of VVT") -

This link tells you when VVT is engaged with stock R33 RB25DET cams -

For running VVT you need a modified internally (so plugs into factory RB25DET loom) 300ZX / Z32 ECU with Nistune installed + Z32 MAF + Z32 MAF plug and a retune. Or use stock R33 RB25DET ECU, stock R33 RB25DET MAF, etc.

Or could fit aftermarket Link G4 ECU or ViPEC ECU + IAT sensor, Mac boost control solenoid with retune.

I also have Apexi AVCR, would I just wire it to that?

No.

You could use a MSD rpm activated window switch to turn VVT on and off -
