Yes, you can use that once you get the Hood
and some fmu. But after you buy those two things your already close to $3000 or more depending on what fmu you use. Then you still need to tune as it wont be tuned at all for your car. So plan to spend a good amount of money on the dyno tuning. So that is why its not worth it. Your already at the price or more than the price of the turbos that are out for the GT and look at its gains, practically nothing. Like 150 whp and 120 tq. Who's gonna pay about $3500 for those kinds of numbers. A stock GTS would still kill you.
