i used a turbo radiator for like a week but didnt like the location of the top hose. It faces right at our exhaust manifold so it needs a 90 degree bend on it at the top and the bottom needed a U-bend. In all I used the stock 420a hoses with a pair of 4g63 hoses. If you were to use a Turbo Rad. i'd recommend using the neon or 2.4l lower water pipe since it will allow you to use less tubing and will keep the coolant lines away from the downpipe.
