This is what you need to know to set VVTI Inlet pulley for 2JZ VVTI

Match it up to crankshaft accordingly.

Remove timing belt, and turn the VVTi intake Cam gear as far clockwise as you can (you may want to turb it back and forth to loosen anything stuck - if it is stuck) Finish by turning it all the way clockwise without disturbing the camshaft. when the VVTi cam gear hits the stop point... make note of the timing mark. if its off. keep the VVTi cm gear turned all the way clockwise and now you have to rotate the camshaft counter clockwise to get the line up notches on the cam gear to match the cam cover.

Timing belt

I just did mine on 2gs4 98 and it was not difficult to do. You also want to consider changing the water pump, idle, tensioner, camshalf and crankshalf seal, and thermostat at the same time depend on your car mileage. Also, watch out for the upper and lower dot to be align before taking the belt out and put it back in. Try to have a proper tools; it will help your job much easier and no short cut. Have fun. the DIY links above it also helps if you are not familiar with all the components, or what to take out and what not. Good luck and let us know how it goes?
