I have been reading about the VVT on the ST and BT 4AGE engines. Do you think you could modify the 16v head (oil supply to VVT activator) and fit the VVT pully.
Would this work? I realise that you would need to activate via ECU and so on but i think the real problem is supplying the oil to activate the VVT.

These are the easy problems - buy a Motec M4/6/800 and tap a large diameter line into an oil gallery. The real issues are cam profile/piston flycuts so that things don't hit things and how much advance/retard to supply and when (read lots of dyno time). Not insurmountable, hence why Toyota made the 20V with VVTi.
Therefore, your easiest solution is to buy a 20V 4AGE. Toyota spent millions of dollars in R&D and you can buy the fruits of their labour from a wrecking yard for less than $1K. It will cost less than the sum of parts you'll need, doing your own R&D and ending up with an underfunded shitty result.
