“Is this it? Have we reached the limit?” When building any platform for racing, there’s a point of inflection when going faster becomes exponentially harder and astronomically more expensive. At that point, the question becomes whether to march forward with the existing platform or to start over from scratch. Whether it’s an aerodynamic limitation or a lack of a reliable drivetrain solution, chassis-specific issues cause tuners to retire old race programs and move on to newer platforms. This calculated decision must be made sans emotion in order to pursue quicker lap times. Text by Jun Chen // Photos by Rob…

Precision Turbo and Engine (PTE) announced the release of the PW40 40mm wastegate. PTE’s new 40mm, V-Band Inlet/Outlet wastegate is constructed from high grade, high temperature stainless steel and billet aluminum components. Featuring a 347-stainless investment cast valve body with a smooth internal surface, this 40mm wastegate provides consistent performance while allowing exceptional flow for accurate boost control. The wastegate includes stainless steel inlet and outlet flanges as well as all clamps necessary for installation. Each PW40 40mm wastegate comes with five different 17-7 precipitation-hardened springs for adjusting boost levels. The wastegate is compatible with most aftermarket manual and electronic boost controllers and comes…

Nearly every auto enthusiast can appreciate a car with the performance to shine on track, yet the utility and comfort to haul the kids and groceries home after work. It’s tough to have the best of both worlds in one vehicle, no matter how you build it. DSPORT staff member Al Rhee, however, thinks that he has it figured out. His once daily-driven Scion FR-S is leaving his garage to make room for the 2017 Subaru WRX STI with its four doors, five seats and 305 horsepower. With his rich car history that included a C6 Corvette, a Dodge Viper…

Extreme Turbo Systems released its 100-percent bolt-on high-flow cat back exhaust upgrade for the new Ford Focus RS. The exhaust system features a 3.0-inch mid pipe that tucks up tightly against the underside of the vehicle to provide more ground clearance than other exhaust systems. The mid pipe connects to the muffler section using a 3.0-inch V-band connection. The V-band connection provides a leak-free seal and allows for a quick-change race pipe for the drag strip. The muffler section consists of two straight-through resonators that route into two hand built 4.5-inch round stainless steel tips. The exhaust mounts up using…

This article just might save your life. Many of us forget that when we crawl under a car to perform any sort of repair or upgrade, we’re trusting a lift, jack stands or a simple hydraulic jack to support thousands of pounds of metal from falling on us. It’s a scary thought. Without these tools, wheel and tire changes, transmission swaps and other jobs that take place around and underneath the car would be impossible. The task of enabling these types of jobs without you getting crushed makes lifting equipment one of the most important types of tools you’ll ever…

R1 Concepts offers its new two-piece replacement brake rotor for the R35 Nissan GT-R. This direct replacement two-piece rotor helps provide consistent stopping power using the factory calipers with no modification required. Manufactured with high carbon, the R1 R-Series rotor offers increased braking performance and strength when paired with high-performance brake pads. A center split core casting provides greater stability and mill balancing with double disc grinding to reduce thickness variations for smoother stopping, minimal vibration and improved break-in. Directional vanes improve cooling to help prevent warping at extreme temperatures. The aluminum hat reduces weight and adds good looks. The…

The WedsSport FT-117 wheel is the latest addition to the WedsSport lineup. The FT-117 is made using a multi-stage closed die forging process that allows the design to be more intricate than what can be achieved through standard mold forging techniques. This allows the single-piece FT-117 wheel to feature a unique split 5-spoke design. The complex forging and AMF process is done in collaboration with BBS Japan and results in a wheel that is strong yet lightweight. This distinctive wheel is aimed at the premium sports car crowd and is offered in 20-inch diameter with various widths and offsets. Available in…

There are only two types of people on this earth. Those who love driving Miatas and those that make fun of people that enjoy driving Miatas. While the ND Miata has an emerging new fanbase, no one can argue that more power would make the car more fun. Unfortunately, the basic bolt-on intake, exhaust and header provide only a snack for those hungry for more power. For those with a real appetite for performance, AVO now offers a complete turbo system solution for the ND MX-5. Designed to provide an OEM fit, feel and finish, AVO touts the system as…

Forced Performance released its new bolt-on turbo upgrade that fits 2001-2014 Subaru WRX and STI models. The FP Blue HTZ turbo couples a 73HTZ compressor wheel rated at 57 lbs. per minute with an FP54 turbine wheel in stock placement housings. This combination provides quick response while delivering enough air to make more than 500whp. The FP Blue HTZ has minimal lag compared to the factory turbo and hits full boost starting at 3,700 RPM to 3,800 RPM. The Forced Performance Blue turbo fits in the factory location and does not require a new intake pipe or the removal of the Tumble…

CP-Carrillo has advanced ring technology to the next level with PVD. This ring coating provides excellent wear, corrosion and scuff resistance. The PVD coating adds hardness and toughness to the ring while reducing friction. CP-Carrillo claims that this coating is better than traditional gas nitriding alone. These rings have a stronger top ring (1.2mm) that can withstand more cylinder pressure before the risk of fluttering. They are highly recommended for high horsepower applications thanks to friction/drag reduction against the cylinder. These rings are offered in a variety of bore sizes. MSRP is $39.00 per cylinder.

It’s no secret that higher boost pressure translates into higher torque and power outputs. Crank up the boost pressure, get more power. While many understand the merits of increasing the pressure of the air going into the cylinders, fewer understand the virtues of decreasing the pressure within the crankcase. While many high-end classes of racing from Formula One to Pro Stock rely upon dry sump oiling systems that run the crankcase at negative pressure (vacuum), few entry-level racecars and even fewer street cars benefit from the negative crankcase pressures of a dry sump oiling system. The cost and complexity of…

NOTHING STARTS OFF PERFECT. BUT JUST AS THE DIAMOND CUTTER refines a rough stone into a brilliant gem, Patrick Kelley transformed this 1990 Nissan 240SX  S13 from a neglected shell into a ride with purpose. Kelley purchased the S13 hatchback in 2006 from a buddy who lost interest and no longer wanted to finish the car. It had an SR20DET engine swap, stock wheels and a flat tire. At the time, drifting rose in popularity stateside and Nissan’s S13  had in turn become the affordable and desirable sport compact, prompting an influx of parts available for the car. Kelley had plenty…

APR released its Carbon Fiber Brake Cooling Ducts for the 2015 and newer Subaru WRX and STI. These ducts replace the plastic trim surrounding the factory fog lamps. Built using pre-pregnated carbon fiber reinforced polymer (CFRP) composite materials for superior strength-to-weight ratio, APR Air Ducts add both function and lightness where it counts. They are aerodynamically-optimized to funnel in massive amounts of air to the front brake rotors. When matched with the optional high-temperature air duct hoses, the APR Brake Cooling Ducts help cool down red-hot brake rotors on the track. Each Air Duct is finished with UV-resistant clear-coat paint…

WHETHER OR NOT YOU WANT TO ASSOCIATE BLUE AND purple headlights with the tuning market, the truth remains that many enthusiasts resort to plug-and-play high-intensity discharge (HID) light kits to increase headlight output. While some enthusiasts have begun to realize the shortcomings of dropping in these cheaply made HID kits, others simply don’t know where else to turn for proper, effective lighting solutions. OEM manufacturers spend hundreds of thousands of dollars researching, developing and testing new ways to improve headlight output without blinding traffic. While most of us may not be able to afford a brand-new luxury vehicle equipped with…
