I've been surfing the web for turbos and i've found a few.
but my goal is to keep the car looking stock. I know that a turbo is hard to hide with all the plumbing. but i want to make it hiden at first glance.
i was woundering if there is a place i can go to custom build my own turbo kit? Or would that be extreamly more expensive?

I dont even think a custom place could hide a turbo that well. Theres just not enough room to make stuff hidden.

is it possible to upgrade the valvetrain on a VVT-i without messing up the ecu?
or with the VVT-i would it make hp to upgrade?
