Come June, a sense of excitement fills the air as Import Tuner held its first annual FR Shootout at Willow Springs International Raceway in Rosamond, CA. Using the Streets of Willow (SOW) track configuration was new to this year's event from the previous Buttonwillow location we had become accustomed to for the past five years of competition. The 1.8-mile track consists of a smaller and tighter layout with a total of 13 turns. For those not in tune with the last year's event, here's a brief recap: The AWD Shootout bore witness to 10 (special invite) vehicles at Buttonwillow Raceway's infamous CW13 configuration, which included three GT-Rs, three STIs, and four Evos in a head-to-head challenge to prove who is the best, or at least amongst the best. ACG's 625hp, satin gray '09 R35 GT-R pulled out the narrow victory over the Kontrabrands/Evasive Motorsports '06 Evo IX SE due to a driver miscalculation on the number of laps, which brought him into the pits after completing only four of five. The error automatically turned the Evo's potential victory into a heart-wrenching DNF. This year marks the sixth consecutive year of the competition, consisting of 15 vehicles of all makes and models-either NA or forced induction-that were worthy enough to compete at our FR Shootout.

The FR Shootout is not your typical weekend track event. It's much more than just a bunch of race cars collectively blasting down the tarmac. These vehicles have more than just a passing resemblance to road vehicles, with many of them being daily drivers; our event rules mandate each car must be registered and insured for public highway use. Continental Tire once again played an integral role in sponsoring this year's event, stepping up to the plate to provide each of the competitors with a set of Extreme Contact DW (340 treadwear) tires as the official spec tire. Among the competitors was an eclectic group of cars, which ranged from an old-school '75 280Z with an LS1-powered V-8 making 420 whp to an intimidating-looking/sounding RX-8 that was prepped and driven by Mazdatrix owner Dave Lemon, and yes, we even brought out a mildly modified '13 Scion FR-S to satisfy the new-school genre. You can say we covered a vast majority of FR platforms we've come to appreciate over the years.

The day started at 7:30 a.m. with a mandatory tech inspection before the cars were allowed to roll onto the track. A 30-minute practice session was immediately followed by a time-attack, with 15 cars leading the way. Drivers knew that they would need to achieve their best times within the early morning sessions; the hot summer heat would quickly kill horsepower, brakes, and tire grip as the day progressed.

The Church Automotive Testing S2000 immediately made its presence known; the supercharged machine fired off a 1:25.707 lap time with former '05 Rolex Series GT Champion Craig Stanton behind the wheel. The Skullworks SR20VE hybrid-powered 240SX recorded the second fastest lap time with a 1:26.278 in the first session. Both competitors and spectators alike were at a gasp as they witnessed the Skullworks machine sending thick plumes of smoke from the rear of the car with every lap. Vehicle owner Mike Yates informed us after his session that a loose oil return hose was the culprit and would be easily repaired in time for the next round. The EVS S2000 stopped the clock with a time of 1:26.918 with vehicle owner and Rob Walker pushing his NA-powered AP2 to within seconds of his forced-induction competitors. Walker was no stranger to the time-attack circuit; he set numerous class records, including the FR Street Class record at Super Lap Battle. During the early morning session, the track claimed its first vehicle casualty. The Phase 2 Motortrend 350Z of Allen Deines suffered catastrophic engine failure as his con-rod punched through his block, forcing the car to retire. Another Phase 2 Motortrend car suffered electrical gremlins due to misfire problems at 4,500 rpm; the KA24 turbo 240SX was unable to make a clean run, which plagued the 380-whp machine for the rest of the day.

As the day's event progressed with five scheduled time-attack sessions taking place, the top cars in the NA class remained with Rob Walker in the EVS S2000 sitting in first, Alex Peng in his 250-whp Momofoolio Racing/Sportcar Motion S2K, and Pit Garage's 350Z driven by Sky Chan rounding out the top three.

The early favorites within the Forced Induction class included the Church Automotive Testing S2000 and Skullworks 240SX witnessed a dangerous competitor within the ranks of competition. The Team FSR Supra owned and driven by Stephen Shiu, a lawyer by day and a track junky on the weekend, was well within striking distance to take the top spot. The Supra, not typically known to handle on the tight SOW course was running in the 1:26 lap time range with a best of 1:26.484, less than two tenths of a second off Yates's 240SX. We caught up with Shiu during the afternoon lunch break to find out what modifications were made to his car: "We built a formidable track car on a budget but made sure not to skimp on upgrading the suspension and enlisting FSR Motorsports Creations in Montclair, CA, to provide vehicle prep work prior to the event. Compared to other courses in Southern California, it is the Supra's least favorite track since horsepower provides little advantage with only two straightaways. Moreover, given that there are many tight transitions, weight is a major disadvantage and we all know that the Supra has a lot of cushion for the pushing."

Vehicle History: "Car was originally purchased new in March of 2000 and modified with an AEM cold air intake, throttle-body coolant bypass, and a Mugen header. Over time, more naturally aspirated modifications were added, and the car was used as the test mule for the Hondata K-Pro EMS system and spent a lot of time on various road courses. Then, in 2008, I drove a prototype Kraftwerks supercharger kit on an AP2 S2000. I knew that if I decided to go forced induction, this would be the way to do it for a street car that had to pass emissions. When an opportunity came up to grab a used kit, I snapped it up and drove around at 7 psi, but eventually upped the boost. After running into the tuning/boost limits of 91-octane fuel, I converted the car to E85 and contacted Oscar Jackson to upgrade the kit. He came up with a special pulley combination that netted us almost 16 psi. The car now makes over 500 hp and has run the standing mile at 169 mph on the rev limiter in Sixth gear. It also traps at 120-plus mph in the quarter-mile, although I confess I haven't launched it too hard for fear of the stock differential breaking, so the e.t.'s are only in the high 11- to low 12-second range."

Vehicle History: "I purchased my S13.5 chassis in its current and painted condition last year from a friend as an unfinished project. I put it back together after building a new engine and rewired the setup with the help of friends and Matt Perkins of SR Motorcars. The initial build was a mild SR20DET with Ross pistons, and MLS head gasket and ARP studs from top to bottom. After a tuning session I pulled the engine due to a rod knock and a failed oil squirter and decided to go with a SR20VE, which I developed all the parts necessary to make the VE headwork on a SR20DET block and modified to allow it to run a Tial V-band turbo housing and wastegate. This car is an evolution of my street 240SX S13, which I drove daily for eight years."

Vehicle History: "My Supra was purchased in 2005 with 18,000 miles in bone-stock, mint condition from an older gentlemen in Nashville for $25,000 in my second year of law school. Soon thereafter, the car was slowly modified (molested) and started participating in the HPDEs a few times a year at the local tracks. With function over form in mind and built on a limited budget, the nearly 20-year-old car has seen simple, minimal, and effective modifications. The car is clearly not a shop car as some of the modifications (e.g., Home Depot backyard-built front splitter), obviously, comes from someone more adept at pushing paper as opposed to turning wrenches. Nevertheless, the more technical modifications to the car and support have been provided by FSR Motorsport Creations in Montclair, CA, which includes engine tuning and management, custom rollbar, electrical rewiring, and prepping for the FR shootout. The result is a 500-plus horsepower car that is amazingly fast in the straights as well as the corners, despite a heavy 20-year-old platform. The Supra has withstood five years of racing on the original motor, is a public street registered car, and is driven (not trailored) to the track."

It was first built as a street car for fun driving through the canyons but slowly evolved with more modifications immediately following my first track day, and the obsession to build the car followed shortly after. After a few different setups, and now being co-owner of a rotary-specific shop (Lucky 7 Racing), the car is running better than ever."

The S2000 was built based on my personal experience both on and off the track. Owning this car for over 11 years, the S2000 has come a long way, and I still believe it's only 60 percent complete. My dream is to one day complete the car so my future son or daughter can share something that has been a part of my life and career."

Vehicle History: "This is my second S2000 I purchased from a good friend with low mileage. It was a good opportunity to build another street track S2000 from a clean slate using all the experience and knowledge gained from my first S2000. From the initial offset, the build of the car was more focused on maximizing lap time using street tires. The car follows Evasive Motorsports' philosophy of maximizing lap time by improving the handling and aerodynamics. For this reason, the motor has never been opened and is still using a stock ECU. The combination of suspension and aero components allows the car to be consistent and reliable, which allows me to focus and dedicate my track time on improving my driving skills."

The goal for my S2000 project is to build the fastest NA race car that is capable of being driven on the street, competitive on the track, and yet still able to carry tools and passengers in the process. The engine was kept stock for maximum reliability. The main focus was fine-tuning the suspension/alignment and aero package to allow the car to cut through every corner as fast possible. We plan to upgrade the powerplant by the end of year to set a new street tire record at Buttonwillow-a goal of mine since day one."

While prepping for the FR Shootout, we spent most of our time and effort to upgrade the OEM bushings to Whiteline and SPL solids. Three weeks before the event, I gave my car to Sky Chan of Pit Garage to prepare for the FR shootout and fine-tune the car with the Continental Extreme Contact DW tires and suspension setup. We were confident going into the event that we would place within the top five among our competitors."

Vehicle History: "I have been into the tuner scene since 1990 and have modified my fair share of cars over the years. In late 2011, I decided it was time to take my passion for cars to the next level and start working on a dedicated track car. Initially, I wanted to build a Honda Civic (FA5) but I had a buddy who wanted to get rid of his '03 Nissan 350Z, and he made me an offer I couldn't refuse. The Z was in good shape, except for the fact that the motor had some issues. I discussed various options with Fontana Nissan and decided to start with a clean slate by installing a new VQ35DE installed at Fontana Nissan. Upon modifying the car, I wanted to use only high-quality parts, which have been proven to withstand track abuse. Sean from SPL helped me choose the right components; I also sourced a set of KW Clubsports, and Whiteline bushings from and a corner balanced and aligned for track use by Darrin and Chris from West End Alignment. As of now, I am very happy with the reliability and performance of my 350Z."

Vehicle History: "In 2004 one of my best friends bought a '03 Mustang Cobra (supercharged 4.6L). This would be a difficult challenge, but I read about people swapping LS1 engines into Chevy S10s. I have a degree in automotive technology and had worked at a VW dealership for three years so I figured I'd give it a shot. A few months later I was cruising around in a Chevy Blazer with an LS1 V-8 and having a great time surprising many people and friends. My friend and his Cobra weren't having any of that, and it was modified with a smaller pulley for more boost at that point. I decided in order to keep up I would reinstall the N2O on the LS1 to try to best the Cobra. The races were always very close but with the Blazer's weight, brick-like aerodynamics, and antiquated suspension it just wasn't doing the job. Then, in 2007, a friend of mine had done an LS1 swap into a Datsun 260Z after seeing what the LS1 did for my '95 Blazer. In a 'friendly' drag race, the 260Z demolished my LS1 Blazer. After researching costs, difficulties, and benefits I decided that was the smartest route to take in order to defeat my buddy's modded '03 Cobra emphatically, inexpensively, and fairly quickly. After scouring Craigslist, I bought two rusty/rough-looking Datsun 280Zs in Fresno, CA, for $500 in hopes of building one functional car to do the LS1/T56 swap. The swap took about four months and was built on my fairly limited teacher's aid budget. Needless to say, I spanked the Cobra on several occasions. This Datsun is a work in progress for me, and as such will likely never be finished but some things I'd like to do in the near future include belly pan/smoothing the underside and closing up some of the massive grille in order to make better use of aerodynamics and increase efficiency."

Vehicle History: "I previously owned a VW GTI show car, but eventually ended up getting bored with the show scene and decided to take it to the track. I had so much fun at the track, even with my 19s and full sound system that I decided to sell the car and buy a new car with FR configuration, but steered clear of the 240SX-my previous ownership led me to become tired of everything breaking. The Z at the time was the best option for the price. Just weeks after purchasing the car, I upgraded the suspension and installed a rollbar. I had previously tried to compete with a local race series, but due to my limited budget, I stopped competing halfway through the season. Even with the abrupt stoppage in the series, I managed to take First Place on the My350Z/G35 forum track challenge in 2011. Now that the suspension and safety are mostly done, my future plan is to start working on increasing power with a custom NA engine build."

Vehicle History: "I purchased the car from the dealership a few months prior to the RWD Shootout with my initial goal to see how the car handles on the track before making any major modifications. With the help of DC Sports, we added a few bolt-on parts to gain 6-7 hp and added a wider/stickier wheel and tire package to improve handling. It might not be the fastest car in competition, but at least it was sure to be the newest!"
