Change the turbo then a tune , then work on the Exh and piping to and from the turbo
My opinion is for those that want the big power buy an older duratec 2 door and do a built engine and add turbo get to 300-350 and have fun
The ST is a very costly car to be adding and changing things for big power
By adding a bigger turbo you will loose the 2500 rpm quick spooling and 4500 nose dive and switching that to 3000-3400 spool and holding to 6000-7000
Most everything with turbos is a trade off
and those are the exact words i was thinking i would get.
i was planning on getting into one but as tom has said the $28000 price tag for an st2 and another 2000-3000 to get it into the 13s. i can take my 03 zxt get a lentech tranny exhaust forged internals some minor head work and fuel management and slap a turbo on it then get a tune from tom and be able to reach into the 250-300hp range for far less then the st. paid 7000 for the car put another 10000-15000 into it and im sure i could manage to outrun a stock st and only have a total of about 17000-22000 into the car.
