If you don't have the VVT / VVTi actuator working how will you maintain oil pressure to keep the cam sprocket fully advanced or retarded to the position where you have set the cams up. You would be better to replacae the sprocket with a standard one except that they don't fit onto a VVTi camshaft. Both the 1JZGTE and 2JZGTE (both turbo'd) have VVTi versions - only on the inlet camshaft. I have a '98 model 1JZGTE VVTi in my Lexus IS200. When you dismantle the VVTi cam gear it is activated by maintaining oil pressure on both sides of the piston. The control of the actuator is a PWM (pulse width modulated)signal - not an on / off signal hence most computers can't control it. Motec and Autronic are the most likely units to control it. You can run without the VVTi with little difference in overall power - you just looose a lot of the VVTi advantage of much better torque at lower revs. It will feel different to drive.
