The oil galleries for the VVTi system are in the head, plus the valve switches. Plus I think the head is shapped to allow the larger VVT cam pulleys. So no, you can not just put a VVTi system on a engine that didn't have it. You would need to swap over the whole head at the very least. Unless you are very keen to re-engineer the whole thing and your Dad owns a machine shop.
Remember that VVT systems do not magicaly give more power. It would be easy to build a motor with fixed cams and sprockets that has the exact peak power as any VVTi /Vtec engine you can name. The difference is that this fixed timing engine may not idle as well, and low end torque may be slightly less.
And in many cases, its not too hard to get MORE power out of a VVTi engine by giving it different cams, even if you have to disable all the VVT stuff. Its just a matter of having the cams avaliable, or getting them made, then retuning with a suitable computer.
So for a 3S-GTE, forget VVTi, and think more about the turbo.
