it can be done, but not without more work than its worth. for the amount of work, you might as well swap the whole engine over. Expect to pay $1200+ for a good engine and harness and all the other stuff you need.
Thanks folks. I don't have big build up plans for my GT, but I found a wrecked GTS. The exhaust looked impresive and the price was right, so I grabed it. I was just wondering what else I should grab while the gettin is good. I bought my GT for the fuel economy, but it's just begging to be some kind of sports car.
