I was also planning to upgrade the turbo after I had bought the car. I am now aware of the header ordeal but hopefully that can be worked out. I found this 25-35psi turbo kit on ebay for $270 shipped which is definately within my budget range-

I am also insearch for an intercooler to help keep the engine cool with the added pressure/power and a blow out valve. I will be upgrading the air filter to K&N aswell for better flow.
