Other thing to consider is the GT's are not re-buildable. You can get 19t built easy now with some very solid 7cm2 exhaust housings available on flebay. I have the 19t -7cm2 and its seems very solid. I am running a 1999 9-3 B204L and put around 315 to the front wheels.... around 360hp I am suspecting at the crank. Torque is insane at well above 400LB at the wheels. Its more than the open diff gear box can really handle unless you are pointed in a straight line and even then it will not get traction till 3rd gear (barely) and that is with 225/40/18 tires. With my 15" snow tires on its just plain silly power.
But you will need full 3inch exhaust from turbo to tail pipe. Bigger injectors, Bigger IC, and all the various tuning of the ECU and fuel pressure regulator that I am not super on top for a 9000.
The 19t will bolt right up to your current location. Yes the GT will spool up faster but I dont notice a big issue with the 19t spool up. It is at full boost by around 3k rpm and can easy maintain this to the fuel cut at 6800RPM. But shifting at 5500 makes the most sense for power.
If you go with anything other than a 19t I would consider the Holset hx35w if your going with a custom manifold its the way to go. Cheap, re-buildable, and only needs an oil line. You can get a new or rebuilt one for under $500. It spools up fast and can get you to over 400hp. You could easy run a tune that is more mellow around 360HP.
But like tires, and oil posts a lot of this is splitting hairs.
