When it was introduced in 1999, the Honda S2000 had little issues in the way of performance. The 2.0-liter four-cylinder engine pumped out a hearty 237 horsepower (176 kilowatt), and at its fastest, posted a 0-60 mph time of about 5.4 seconds. 

Under the hood of this one, though, is something much meaner than a stock four-cylinder. The 2.2-liter engine (per 2005 and newer) has been boosted to a jaw-dropping 600 horsepower (447 kilowatt) at the crank - and you can 'Buy It Now' on eBay for $20,000.

All that newfound performance comes courtesy of a Kings Performance Stage 2 turbo kit. At the wheels, it will put down 505 horsepower (377 kilowatt) on 93 octane fuel, and includes a number of upgrades. The upgrades range from KP Bosch 1000cc injectors, to an Omni Power 4 Bar MAP sensor, to new Bridgestone Potenza Pole Position wheels, and of course, a roll bar for added safety, just to name a few.

The seller, Kings Performance of Orlando, Florida, says that this S2000 is the “world’s fastest street-legal” example on the market, and cost over $18,000 to upgrade. Just over 92,000 original miles are on the odometer, the manual gearbox remains, as does the original red and black interior, and most of the exterior parts are stock, making it the ultimate sleeper. 

So if you’re in the market for something dangerously fast, look no further.
