So yeah get the FRS...
FR-S with half the Hp for $26,000 and and only 240lbs less.
Supercharger is about $5k and turbo about $6.7k
Labor and tuning doubles up cost. $13k.
26+13=$39k. Your probably around 400hp as well. You have no oil cooler, you're still on prius tires. Your suspension setup is not set for double the Hp. Proper Lsd needed plus you will need rims to accommodate your frilly tires. Figure another 15k.
Your do kit 180lbs
Your oil cooler and new res about 50lbs. So figure 230+2866lbs.about 3100lbs. Then your comparable light wheels, $2900-4000.

You will be paying about $48k-55k to have a comparable to superior car. But the stock turbo Z will be a better car for the money with better torque to boot. The stock turbos would make it cheaper to mod. And produce more power for the Same amount of cash as your FRS.
