If you had the K14 as a stock turbo it will bolt up no problem, the intake doesnt fit after....so you would have to get a 1.6 intake. Inlet on the turbo is bigger.
You will also have to cut one little piece of the intake manifold, and the oilreturn line does not match up 100%. Some modification will be required....I just made a new stainless line 3/4inch ID, goes into the pan. Stock location blocked.
If you have a K03 turbo then you will have to change the exhaust manifold aswell, Along with all the other mods listed above.
