The Honda S2000 is one of the most desirable Japanese sports cars of its era. From its attractive looks to its peppy 2.0-liter inline-four cylinder engine that produced as much as 247 horsepower and 161 pound-feet of torque, the S22000 was as desirable as any sports roadster that hit the scene at the turn of the millennium. To this day, interest in the S2000 remains strong, in large part due to the seemingly limitless tuning possibilities it provides. Take this particular S2000, for example. It belongs to Mason Whitlow, an employee of tuning shop Holley, who bought his S2000 in standard form, only to have it upgraded into a complete monster on four wheels. It’s still a Honda S2000 in form, but everything else is entirely different. We’re not talking about a spunky 248-horsepower sports roadster anymore. This S2000 is now a 707-horsepower beast of epic proportions. At the very least, this build is a rolling advertisement, not only of Holley but, more importantly, of the many ways people have grown to love the Honda S2000.

What kind of modifications did Mason Whitlow added to his Honda S2000?

The upgrades are extensive, to say the least. Remember the S2000’s 2.0-liter inline-four cylinder engine? Whitlow, with the help of his employer, ditched that in favor of a massive 6.2-liter L92 V-8 engine. Of course, a significant engine swap like that involves more than just an engine-for-engine replacement.

To get the desired results, Whitlow also added a Boostlab 7874 turbo, upgraded the car’s camshaft and valve train, and installed more sophisticated engine mounts. That’s on top of all the other additions to the S2000’s small engine bay. Take a peek a the completed engine swap and you’ll see Hooker exhaust headers, a Hi-Ram air intake system, and a 105-mm throttle body.

The result of all these changes is beyond belief.

How much assistance did Holley provide

A lot, presumably. Whitlow, after all, is a jack-of-all-trades employee who has access to just about every mechanical nook and crank that he needs to successfully make the conversion. He even managed to score a beefed up four-speed automatic gearbox, and Performance driveshaft, and an 8.8-inch Ford rear end that’s equipped with 3.37 gearing.

All the modifications put into this Honda S2000 is the stuff of awesomeness. It’s incredible enough that a Honda S2000 can be modified to this extent; it’s more amazing when you see the completed transformation. Go big or go home, right, Mr. Whitlow?
