SUPER AUTOBACS KUMAGAYA EVOLUTION Q S30

Magazines available here!

The S30 Fairlady has a very bizarre culture of customization that surrounds it. You would assume it would be customized along the lines of more traditional Japanese automotive customization like Kyusha, Kaido, or Shakotan. Instead there is another sub-culture in Japan that loves to do more American things with the S30; they drag race them. The S30 used to be a very popular choice amongst Japanese drag racers before the Supra and BNR32 came along in the late 80s. It is such a fascinating take on what the Japanese see as a drag racing car. I love the combination of American muscle with the Japanese flare. This is Super Autobacs Kumagaya’s “Evolution Q” S30 Fairlady Z!

Evolution Q

ENGINE

The engine room is dazzlingly dressed up mainly with chrome. Looking at the surge tank, you can imagine that the tuning is completely different from the methods used at the time. The ignition system from a RB engine, and the drive is by F-Con V Pro. The turbine is a T51BB.

To match the high-powered engine, which will have at least 500ps, the body is reinforced with spot reinforcements and a strong roll cage is installed. The overall image is inspired by drag machines, which the owner loves. Although it is dashboard-less, attention has been paid to the details, such as the cover to hide the wiring made of carbon.

THE LATEST ENGINE MANAGEMENT CHANGES THE STANDARD!!

The S30 is a popular model that has become a standard in this corner. There is no need to introduce its origins. By the way, the S30Z has a lightweight and stylish body and is equipped with a L-type engine that can be tuned in a wide range of ways, so it has been used in a wide range of stages. It is no exaggerations to say that is has been used as a tuning based for any genre, from circuit to rally, drag races, and top speed. The vehicle we will introduce this time was created with a strong focus on drag racing. It is equipped with a S-type turbo engine, which can be said to be the highest peak. When you hear the L-type engine, you may feel that it is different from the vehicles introduced in this corner, but the accessories and controls have been completely updated to the new generation. When you hear the F-Con V Pro and the T51BB turbine, you probably don’t imagine that we are talking about the S30Z. So, the engine, which has been given the latest L-type tuning, has eliminated the distributer and is equipped with the RB engine’s crank angle sensor, direct ignition system, and six-stroke sports twin injection. The basic control is that of the RB26DETT, and the computer is left to F-Con Pro. With the introduction of this control system, the turbo spec, which was once said to be “difficult to ride and difficult to master”, can now be expected to provide stable driving.

The clear cut lenses of the headlights are fitted with HIDs. The center dual exhaust is designed to increases silencer volume. There are plently of interesting features, including an oil cooler built into the front spoiler. The bonnet scoop that gives the car an impressive image was installed by the owner, who prioritized style.

Now that it has been completed, it is ready for street use. The interior, exterior and engine have been refined. It has been tuned to a completely different dimension from the cars of the time, and the S13 Silvia is installed in the front, BCNR33 in the rear, 5-speed dog box, front suspension, HKS transmission in the interior and exterior will captivate your eyes, and it will also evolve into a drag conscious system.

The luggage space is fitted with a safety fuel tank and NOS bottle, which are beautifully chrome-plated to match the overall concept.

The front is a combination of S13 struts and ER34 brakes, while the rear is a combination of BCNR33 GT-R multi-links and BNR32 suspension, etc. This not only increases mechanical grip, but also has the great benefit of allowing the use of current suspension kits.
