Well the VVT-i came on just more than the 2j's. Its sorta like Vtec on hondas. The turbo and n/a 1j's and 2j's even had it on some of them. its just a big pain in the ass when you start to modify it. Thats probalby why a turbo "kit" is not offered for a car with the vvt-i. If your car does have VVT-i and no one offeres a nice bolt on kit you will probably have to faboricate your own. Its completely possibile just will make it a pain in the ass.
