Well, I hope some of those aftermarket parts are a larger turbo and a free-flowing muffler. To take that car on, even if it has an LS-1, you'll need to bump up the stock horsepower and increase the low-end torque. I saw a head-to-head with this model Supra and a Corvette. The Corvette had a distinct horsepower advantage with both in stock form. Good Luck
