Do anyone with a teg type r, has a turbo on it and how much for the turbo?

What additional mods do you need for it?

Also what brand is the turbo?:) :)

I don't know anyone personally with a Turbo ITR, but I do know that you can boost it with a basic turbo kit. Those things would cost around 2 to 4 grand, depending on the brand/type. These kits usually boost 5-6 psi in stock form, and my guess is that it would be ok even for the high CR nature of the ITR.
