I think you can piece together a good na-t kit with some used parts and a rebuilt turbo for cheaper than that though, unless the is300 is alot harder to go na-t than an sc300.
Putting it together isn't going to be the problem, but your going to have to run a stand-alone. Or a bad ass piggy back, cause VVT-I is a pain in the ass to tune.
