does anybody have a 12 turbo or know anybody who is selling one, not the motor just the turbo

 

you dont want that turbo, it's soooooo small! get a s5 turbo

 

where can i get one how much and how many mdifications would i have to do to make it fit

 

To make a S4 or S5 TII turbo fit, you need to put the 12a exhaust gasket on the manifold, mark it, then grind it so the manifold matches the 12a gasket. Then get a J-Spec 12aTurbo intake manifold, or use a different carb, like a weber.

OR

Make a custom exhaust manifold so the turbo will not hit the stock intake manifold.
