2006 Acura RSX Type S - K24 Drag Build

Breaking the 9-sec barrier at over 2,600 pounds

It goes without saying that speed is the motivating force behind many an automotive hobbyist. The euphoria that it produces is unmatched and like just about anything good, it keeps you coming back for more. Once you experience that high, you find yourself addicted. The good thing about speed is that you can always go faster, depending, of course, on how much you're willing to do in order to achieve it. You're really only limited by the restrictions presented by your chassis (which you can continue to alter), the depths of one's pockets, and the willingness to put everything at risk for the sake of speed.

Drag racing has, and continues to be, a staple in our community. For every car show and meet that you encounter, there are just as many import drag racing events occurring throughout the nation. It continues to evolve because going fast simply never goes out of style. Another great thing about being fast is that not every run-of-the-mill schmuck can do it; it requires hard work and dedication. Fortune favors the brave and some reach heights that none before them could muster. The beauty of competitive (and sanctioned) drag racing is that it offers a numerical value in the form of time that then creates a precedent for racers to strive toward. These times then turn into goals for many and records for the select few. They say that records are meant to be broken and this fuels the spirit of competition.

JR Hurley knows a thing or two about going fast. In fact, he might own the fastest (complete) DC5 chassis anywhere in the world. Though his "record" is unofficial and met with a bit of controversy, JR stands alone as the first RSX street car to break into the 9s. Some would question if this particular RSX is truly a "street car," but it does indeed fulfill all of the requirements to classify it as a full-bodied street vehicle. The 9-second pass isn't a fluke by any means either. It's documented on video and JR has made multiple, consistent passes in this car.

"This is a street car that meets all the rules to classify it as that," JR says. "My RSX is registered, insured, and driven on the street with all the original body panels intact. Every other RSX that has run 9s is basically just a shell with tube-frame chassis, one-piece fiberglass front ends, and one-off suspension components. They are 'Pro Stock' vehicles, mine is a true street car."

Though technological advances have produced some incredible quarter-mile times in the Honda community, JR still faced many obstacles on his way to running a personal best of 9.76. High horsepower, heavily modded Civics and Integras breaking into 9-second territory are pretty common these days, but an RSX with full interior that weighs in at approximately 2,650 pounds? Not so much. Never mind that, how often do you even see a DC5 drag car at all? All things considered, JR's accomplishments with this heavy, unpopular drag chassis are incredible to say the least.

JR had always had his sights set on being involved with FWD drag racing, but the DC5 platform wasn't his original choice. As he tells us, "When I was originally looking for a car back in 2005, the first one I looked at was actually a Chevy Cobalt SS. It didn't really spark my interest that much so the next car was this Vivid Blue Pearl RSX Type S. After I testdrove it, I was sold. It was the last production year of the car and the dealership only had two blue ones left so I immediately bought it. It wasn't one of those cases where I just started out adding parts mildly and caught the bug or anything—I went into it knowing I was going to start modifying the car right away."

He broke his DC5's proverbial cherry by installing a race header, full A'PEXi exhaust, and an AEM intake. No time was wasted before he took the car out on its first quarter-mile run, which yielded sub 14-second passes. Dissatisfied, JR found himself researching turbo kits, which led him to Honda engine specialists InlinePro. One of their turbo kits was purchased and quickly went onto his stock K20. Off to the track he went where he was able to power the RSX down the 1320 into the 12s. It was a 2-second improvement over his previous setup but it just wasn't enough to satiate his hunger for more.

"Boosting the stock motor definitely helped make the car faster, but I came to the conclusion that I really had to tear the whole thing apart to really get the low e.t.'s that I wanted. During this whole process, I was still driving the car daily and it had air conditioning, power steering, and all other amenities. Tearing the engine apart would obviously make driving it a little less convenient but it was necessary," JR says.

The factory 2.0L was pulled and never the same again as InlinePro stepped in and reworked his setup completely from the inside out. The factory K20 block was removed and in its place was a larger InlinePro race-prepped K24. Their block was filled with their signature connecting rods, billet crank, CP Pistons, ACL race bearings, and everything needed to withstand the pressures of forced induction. Up top, the cylinder head remains a K20 unit, but this too saw the complete InlinePro treatment. A return-style fuel system was installed with dual Bosch 044 pumps to supply plenty of fuel to the freshly built motor. To get the power to the pavement, a Pfitzner Performance Dog Box was installed along with a custom final drive. His upgrades proved to be worthwhile as he was able to claim the title as the first street RSX to break into the low 10s. As you would expect, even that wasn't enough to meet his level of satisfaction—he wanted more.

Building, racing, and rebuilding began to take a toll on JR however. The emotional highs of breaking his own personal best times coupled with the lows of being displeased soon after led JR to a three-year hiatus from racing. There were some health issues that needed attention as well as surgery and recovery. His RSX lay dormant throughout that period but he was still adding parts to rework his setup. A 10-point rollcage was fabricated and a parachute mounted for added safety. To maximize efficient power production, he had Full Race create a one-off sidewinder manifold. The centerpiece to this latest arrangement is a 67mm Precision turbocharger. In 2012, JR Hurley made his return. Still weighing in at a stout 2,650 pounds, the RSX made its way off of the trailer and blasted down the quarter-mile at 9.77 seconds.

"It was the happiest day of my life so far! To break the 9-second barrier was almost unbelievable. The car still had traction issues and even we thought it might have been a fluke until we backed it up with another 9-second pass." Nines were cool, but it wouldn't fit his character if he wasn't already looking at illusive number eight. "I got to feed the need, man. Maybe I'll try a larger turbo manifold and change little things to see where it takes us. I'm already the first RSX street car in the 9s; why not shoot for 8s?"

I would like to thank my father foremost for helping me fabricate parts, assemble stuff, oversee things I may have missed and supporting the sport that I love to do, along with my mother who worries every time I go down the 1320. Thanks also to my sister for supporting me and giving me the garage to build the car. I'd also like to thank Nate Conquest, part of my team and pit crew who is always there to offer advice and lend a hand. I'd like to thank Alex at Konstant Design for the great Sudden K Racing apparel and car decals. Rich Bogart from Bogart Racing wheels for the best custom drag wheels, and Frank Rehak at the Drive Shaft Shop for allowing power to go to the hubs. I'd like to thank Ricky Dukes and C&K Lord for their time. Thank you to The Sauce Spot and to Faiz Rahman for shooting my car. Finally, credit goes to InlinePro for supporting me and helping me reach my goals; John Lee at InlinePro was instrumental in answering all my questions and concerns since day one of building this monster.

Sudden K Racing
What is truly impressive about JR Hurley's journey is that he's always done a majority of the work himself. Though InlinePro played a huge part in putting his engine together, practically everything else was done by JR himself with some help from his father, Jed Hurley Sr. Together they are "Sudden K Racing." A quick glance at his mod list in this story reveals a bevy of custom Sudden K Racing products, which are all components made by the duo. They don't have an official website but you can find them on Facebook.com by searching: Sudden K Racing.
