sounds like alot of work for nothing..you need aftermarket log or custom manifold (250-1000$)..unless you can find something to cheaply modify as turbos dont have same flanges..then you also need a custom downpipe another 200-400$.not sure about oil and coolant feeds but probably have to modify them..
doesnt seem logical for not much of a difference..might as well get a ko4 which is much simpler to install and have cheap parts already out there to bolt it on
and not to mention that t25 turbos are garbage and self destruct once you start pushing them past 15-16psi
