The famous slogan, “In a world of compromise, some men don’t” is an apt maxim to describe the perseverance needed to attain one’s ambitions. Far too often, compromises and concessions force people off track from their ultimate goal. Whether it’s career aspirations or a car build, issues such as availability, money and opinsions get in the way for many people, preventing them from achieving their objectives. Text by Richard Fong // Photos by Michael Ferrara STICKLER FOR SPECIFICS Ashton Makenzie agrees with the motto above. “I always set my goals high for my project car builds,” he said. “For my…

Once a year, Fuji Speedway becomes the gathering grounds for nearly every Nissan motorsports enthusiast in Japan. After a hiatus in 2012, due to NISMO’s relocation to Yokohama, Nissan enthusuiasts and their vehicles gathered at Fuji Speedway at the base of Mount Fuji on December 1st for the long-awaited NISMO Festival 2013. From the iconic Nissan race cars that some only know about through Gran Turismo, like the R390 GT1 and the JGTC NISMO R34s, to the 1970’s era KPGC10 Skylines and late 1990s NISMO 400Rs, Nissan and its enthusiasts filled the festival with passion for motorsports.

Pony cars have been the benchmark to beat since the birth of the import performance industry nearly 30 years ago, and the Mustang continues to be a solid contender for domestic-car fans and a favrotire to side with whenever the domestic-versus-import argument arises. This battle between imports and domestics still rages to this day, especially amoung many American servicemen deployed on bases all over the world. Fortunately for import fans, there are always plenty of new challengers to give the Mustang a run for its money. Text and Photos by Richard Fong ZOOMING Z The argument for imports is compelling…

To be the star at one auto show is commendable. To be the star at two in one year is a feat. For Subaru, the 2013 auto show season kicked off in late March with the unveiling of the WRX concept at the New York Auto Show. For the rest of the year, Subaru fans and enthusiasts were abuzz in anticipation of the new WRX. Rumors circulated about a two-liter turbocharged engine, along with a number of improvements, to go with the all-new design, and as the Los Angeles Auto Show approached, the buzz got louder when Subaru announced it…

Missed opportunities can often be hard to forget, especially when shopping for a unique item. If a second opportunity were to come up, it would almost feel like hitting the jackpot. Just don’t fail to pull the trigger, lest you will discover the definition of “great disappointment.” Text and Photos by Richard Fong Lurking and Trolling While surfing the web and forums, Mark P. stumbled upon a build thread that captured his attention. The vehicle, a Datsun 510 with an SR20DET engine swap, ounded like a perfect streetcar. In his words, Mark felt that it was “the ultimate ‘not designed…

Racing is a rush for everyone, from the spectator in the stands to the driver and the team of technicians who feverishly prepare their vehicle for competition. For Ricky Silva, participation in drag racing started in the pits. He stated, “I worked for Bryan Jimenez and Marty Ladwig on the GM Racing Sport Compact teams from 2006-2008. In 2011, I worked on the Gardella Racing Formula Drift team. In my spare time, I help Fernando Cunha at CLM Motorsports.” Working with quick and competitive racing teams taught Silva valuable lessons that he would later on employ in his decision to…

You guys are probably the only ones to have ever measured and discovered that issue. This is a statement that we are hearing more and more as we delve into the uncharted territory of extreme Honda performance. While people have been racing boosted B-series Honda engines for nearly 20 years, the engineering level of the development has been predominantly “grassroots”. The issues that we are uncovering while attempting to extend the life of a 1,000whp boosted B-series won’t be found under a forum thread. Instead, DSPORT is finding the limits and solutions using engineering, accurate measuring, precision machining and scientific…

Man and machine versus the clock; this is the essence of time attack. Conducted like a qualifying session for traditional motorsports, time attack started as a competition for tuning shops to compete using their streetcar builds. It has since evolved into a professional-level competition, only with few performance restrictions, save for the requisite safety mandates. Text by Richard Fong // Photos by Pole Position Images and David Lynsien/WTAC Australians take just about anything they do to the extreme, which makes Australia the likely host country for the World Time Attack Challenge. Started in 2010, the WTAC invited the quickest machines…

There is nothing as unnerving as blasting through the traps at triple-digit speeds only to find that the brake pedal has turned into a cinderblock. If you have ever been in a car that’s lost the assistance of the power brake booster, you know how “rock hard” and uncooperative the brake pedal becomes when the vacuum source is lost to the booster. Vacuum assist is also used on some vehicles to reduce clutch pedal effort too. Unfortunately, installing a set of “big” camshafts in an engine will significantly reduce the strength of the vacuum produced by the engine. The result…

Dead or dying batteries suck. Did you leave the lights on? Is your alternator going bad? Does that high tech alarm that can start the car and communicate with you from two miles away leave your battery drained after you go away for a week? Or has your once-great battery been sitting on a shelf waiting for you to finally get your project car back on the road? Regardless of the circumstance, batteries have a limited life. However, properly caring for your battery is the best way to extend its service life. Text by Richard Fong // Photos by Jun…

You must walk before you run. Despite what commericals say, unless you have perfect running technique and form, the latest and greatest from Nike isn’t going to help you win a marathon any more than a good kick in the ass would. Like running, racing a car requires maintaining a balance between upgrading equipment and developing proper driving technique. Getting caught up purchasing the latest equipment can blind people to the fact that they need to invest more time learning how to drive. To compete in wheel-to-wheel racing, two criteria have to be met; first, the vehicle needs adequate preparation,…

The hottest sport compacts to fly off the showroom floor have been Subaru’s BRZ and Scion’s FR-S. These fraternal siblings, born of a joint venture between Subaru and Toyota, have received innumerable praise from the media and consumers for its styling, performance and value. With a low roll center that rivals that of supercars, the BRZ and FR-S have tremendous handling capabilities. Coupled with the new FA20/4U-GSE boxer engine that features both direct and port injection, tuners have really taken notice of this platform.
