It's got a 254whp built K24A2 engine, a bunch of Skunk2 engine parts (obviously), Hondata ECU, Brembo GT brake kit, Volks, Sparco seats, and a Skunk2 suspension. They're asking $17,000 for the car. Without knowing the year or mileage, we can't say how much a stock Si would be worth. Give them a call if you're interested.
