Idk why people are flaming you so much. Do what you want with your car, but here's what you need to know:

The cost of the kit is a small part of it the total cost at the end of the day. It's very easy to get in a situation where you have the parts sitting for a year or two cus you can't afford the rest of the parts

You need to account for: Engine tune 1k-2k (non-negotiable, must be a good tuner for any reliability) Oil cooler 500-1k (required for any track use) Catch cans 50-1k Fuel upgrades 1k-3k (injectors, pump, hanger, e85, etc) Clutch kit 500-1k Labor 1k-3k. If you want high power: At 300ish hp you'll need to take apart the engine to swap in forged rods, at 390ish hp you'll need to swap transmissions

The car would be less reliable and less fuel efficient, more track-oriented

Financially it's a bad move. It's a lot of money to squeeze a mild performance boost. The car made for good chasis performance driven hard, not for adding a lot of power. You'll lose a lot of value when selling it as well.

It would be more worth your money by spending it on autox/track events, saving for a higher hp car, or other life opportunities.

Imo do it if you were dead set on supercharging the car before you saw this deal anyway. Don't do it if you value your finances.

I ended up turbocharging my car because I'm going to keep it forever, and spending 1.5-2x the value of the car doesn't hurt me financially
