All the Lexus Vehicles you mentioned in your first post all share the same motor. Yes it does come with VVT-i and yes there is just as much aftermarket support for these as there is for the non-VVT-i motors. The VVT-i and the nonVVT-i do have some differences such as intake location on the updated models.
