will a t67 turbocharger fit a 06 civic si with a custom kit?

Answer 1

You can fit anything to any vehicle, you just have to have the experience and the know how. In your case there would have to be many modifications to acomodate any turbocharger unless you can get one already configured for your model. On top of it all you will need the sofware to tune up your computer, or will have to find one that you can install and program your self.
