I wouldn't touch it to be honest. The VVT-i probably is actuated from oil pressure, and to start with you'd need to sort this out (dunno where it taps to). Then u gotta consider that a BEAMS 3S-GE is entirely different: 12.5:1 pistons, different cam profiles are the major ones. With this in mind, you need to consider that the VVT-i maps would non longer be relevant if installed on a 3SGTE, 'cos the pistons are lower compression and the cams are milder. You could make it work, but consider how much R&D Toyota puts into these things, and compare it to your budget. Can u afford countless hours on the dyno, and constantly purchasing new custom cam grinds?
It would be more fruitful to turbo the BEAMS engine with, say, 6 psi boost. But then again, it wouldn' have the top end of a high boost 3SGTE.
That's how I see it. I could be wrong, however, but don't let anyone stop you from doing something different.
