High oil consumption, excessive smoke through the exhaust, high blow-by, lower than expected power output and increased oil contamination are just some of the possible results of an improper engine break-in or run-in. While production engines in new vehicles are already “broken-in” at the factory, any high-performance “built” engine requires a proper break-in procedure to ensure peak performance, minimal oil consumption and a long life. Even if the best parts are used and the proper machining and assembly was executed, an improper break-in can result in some or all of the negative consequences. While there is no universally agreed upon…

Chances are you’ve fallen into watching an episode of Iron Chef. If you haven’t, the format pits visiting chefs against one of the resident Iron Chefs at Kitchen Stadium. Both the visiting and Iron Chef must come up with original recipes around the same theme ingredient. When Club DSPORT was tasked with building a number of Toyota 2JZ engines for different applications, we thought there would be no better way to showcase the versatility of this popular platform. After outlining the origins, strengths and weaknesses of the 2JZ engine platform, we’ll showcase a detailed and complete 2JZ build for circuit,…

There is nothing more frustrating than being part of a two-man team where you are doing more than half the work. When subtle hints don’t get the lazy half up to speed, the end result can be a very vocal argument. Each of the turbos on a twin-turbo engine feel the same way. When the work is unbalanced between the two turbos, you may even hear the turbos arguing (in the form of compressor surge). Fortunately, twin-turbo engines that utilize actuator-type integral wastegates (with adjustable rods) can be “synched” to provide similar wastegate performance from each turbo. After outlining the…

Just like with a turbo upgrade, you can’t expect to bolt on new suspension hardware and realize gains right out of the gate. Obtaining peak performance requires adjustments, tuning and an understanding of how the pieces work in conjunction with each other. Perfecting a suspension system is a daunting task, as it is arguably the most complicated system of any performance vehicle. Most typically focus on stiffer dampers, springs and sway bars when upgrading the suspension. Although these upgrades usually improve handling, the effectiveness of the system also depends on the lengths, angles and linking points of the suspension system.…

Quick Test: GoPro Hero5 Black and Karma Grip Over the course of a decade, GoPro went from being the single dominating action video camera in the industry to a drop in a pond filled with countless other options. The world-famous company has since steadily introduced updated models on a regular basis, a must-do in order to stay ahead of the many competitors entering the market. Now, we find ourselves with GoPro’s latest iteration, the Hero5. The new model sports updated hardware and interface, rolled into market alongside the Karma Grip gimbal in an attempt to lasso users into the GoPro…

In the automotive world, heat creates a ticking time bomb. Different vehicle components demand target temperatures for ideal performance, but you’ll run into trouble quick if things get too hot. In the search for performance, items like cooling components and tires must be closely monitored to create an ideal setup. Although tools like infrared temperature guns provide vital information, they only deliver tiny snippets of a bigger picture. This is where infrared cameras and thermal imagers come in, offering users the ability to view temperature differences of an entire area on a digital screen. We received Milwaukee’s M12 102 x…

Exhaust systems serve as one of the most important upgrade decisions you’ll make for your car. This hardware determines in part how your car will look, sound and perform. It makes a statement on what type of enthusiast you are, as car owners look for different benefits and characteristics. But how do you determine which exhaust best fits your needs? We decided to do the dirty work for you, as we selected 12 currently available exhaust systems for the 2015+ Subaru WRX and STI, and thoroughly evaluated their sound, appearance, build quality and performance on our D’Garage 2017 Subaru WRX…

Since the VAB Subaru WRX came to the market for the 2015 model year (check out DSPORT Issue #137) this platform has proven a favorite in the segment, especially by its loyal fanatics. DSPORT’s sales director Al Rhee recently joined this fraternity of loyalists when he purchased this 2017 WRX STI as his new daily driven family taxi. The beauty of this machine lay in the details, including its turbocharged EJ257 engine, all-wheel driveline and the VAB’s improved chassis stiffness (compared to the previous generation chassis).

Bent or warped valves and reduced engine efficiency have plagued our 1,300+whp RB26DETT engine ever since we pushed beyond the 1,000whp mark a few years ago. For the longest time, we chalked up the bent or warped valves to extreme temps and the rigors of life at 600 horsepower per liter. Thanks to new discoveries made in our Club DSPORT engine development center we’ve not only isolated the true cause of these issues, but also have discovered a solution to eliminate the issue at this power level. To see if your engine can benefit from this solution, we will first…

What’s the point in upgrading your car if you don’t know how to drive it? There are countless options in improving your performance on track, yet improving the driver is one of the most commonly overlooked. It can be a tough task, as it requires you to set your ego aside and learn how to do something you may think you’re already good at. It doesn’t sound as sexy as a bigger turbo or a shiny new set of coilovers, but once driving techniques start to click in your mind and become second nature, you’ll discover an entirely new element…

No one would argue that the RB26DETT is one of the best inline six-cylinder engines to come out of Japan. Depending on the qualities that you prioritize in an engine, some could make a valid argument that it is even superior to Toyota’s 2JZ-GTE. The engine’s success in motorsports and the records it has set in the tuning world have put it in the upper echelon of performance engines. While it is one of the most expensive engines to build, it does offer some options unavailable in other platforms. In fact, it is the only Japanese performance engine where the…

2000 Honda S2000 Clutch Install Our project Honda S2000 clocks in with 366,000 miles on the odometer, with only two clutch changes in its whole life. As put together plans to bring the car back up to snuff, a new clutch was added to the list. Given that the car will likely see some mild power upgrades and track time in the future, we opted for some more capable hardware, McLeod’s Street Tuner clutch. Scroll down and learn some of the essentials in swapping a clutch on the Honda S2000. Text and Photos by Cameron Parsons A lift isn’t a…

2000 Honda S2000 Polyurethane Bushings Install In Issue #170 of DSPORT Magazine, we upgraded our project 2016 Mazda MX-5 from factory rubber suspension bushings to Energy Suspension’s Hyper-Flex polyurethane bushings. Although the car was new and the stock bushings were in perfect condition, we still discovered significantly improved lap times along with better driving characteristics. These benefits are only exaggerated when upgrading heavily aged cars to polyurethane bushings. Our D’Garage project S2000 had stacked up 366,000 miles on the chassis, still running on the factory rubber. As a result, the car inhibited unwanted driving characteristics and even a level of…

While you can always turn up the boost on a forced induction application to mask a poor parts selection, an All-Motor combination relies upon the proper matching of camshafts, header, cylinder head and intake manifold. Among these four components, headers usually represent one of the first upgrades for any All-Motor build. The relative low cost and ease of installation leads to its popularity. When it comes to the Honda B-series engine, the number of header choices is overwhelming. BLOX Racing recently introduced titanium versions of its Hi-Flow and Max-Flo 4-2-1 headers and we decided it was time for a quick…

COBB Tuning Subaru SS 3-inch Cat-Back Exhaust P/N – 515132 Cobb Tuning’s Subaru SS 3-inch Cat-Back Exhaust for the 2015+ WRX and STI features a TIG-welded 304 stainless-steel construction with one resonator and two mufflers. The exhaust employs a stamped flange at the down-pipe and laser-cut flanges at the Y-pipe, allowing for simple installation and precise fitment.
