On day 2 of the 120 Hours Week To Wicked build-up, the crew, with plenty of help from GReddy, installed most of the hard parts from GReddy's newly revamped, bolt-on turbo kit. The system includes everything you could possibly need in order to boost your S2K, and with everything fully installed, that point was proven with absolutely no "extras" needed to complete the process.
To complement the turbo system by opening up the exhaust flow, a three-inch GReddy Performance Products RS Race cat-back exhaust system was bolted on. Originally introduced at SEMA 2017, the system does not incorporate a resonator in the exhaust path like most exhausts, and instead offers uninterrupted flow to its muffler and exhaust tips. Even though this is a single-exit setup, GPP offers a few options to finish off the exhaust, including a titanium tip and a downturn. In addition, a baffle is also available to bolt into the end of the muffler to bring down the decibels. Ideal for use with naturally aspirated or turbocharged applications, the RS Race system will be available at an exceptional price point of just $499.
As with any turbo application, fuel and engine management is crucial, and to the end GReddy's E-Manage system was installed with their included plug-and-play harness, and to fuel the fire are a set of Deatschwerks 600cc injectors that use factory-style connectors for a pain-free install. In order to control and monitor boost, GReddy also brought their ultra-sleek, very compact Profec Electronic Boost Controller, which we mounted just to the right of the steering column. Able to display info in digital, bar-graph or graphical views, the OLED display is easy to read and bright enough to see clearly even during the day with the top down.
Another addition on the electronics front is AEM Electronics' X-Series air/fuel ratio gauge. Well documented as holding the title for fastest response time and incredible accuracy, we were already familiar with the X-Series unit from the testing that had taken place in 2016. Beyond the precision of their wideband, AEM uses an incredibly slim design that allows you to mount it just about anywhere you'd like. For our build, we wanted it in plain sight of the driver, but not able to be seen by other cars on the road, so we made a quick aluminum mount that easily attaches to the inside of the radio door with a single screw mount.
After turning the last few bolts on the turbo kit and finishing off the electronics upgrades, we turned to ENEOS for the vital fluids. The name should sound familiar to anyone that pays attention to Japanese car culture, but in case you're in the dark, the company has served as a longtime supplier of high-quality products to Japanese OEMs. Almost two decades ago the brand started supplying and sponsoring Honda's Formula 1 race team and its products were widely used in countless racing series like Super GT. Being that they're experts in the world of oil, when they were given a breakdown of our build they immediately recommended ENEOS Racing Street 0W-20. A full synthetic formula, it's specifically engineered for high performance engines, and after adding boost to our 130,000-plus mile F20C, we wanted to make sure we're running the very best through its veins. With GReddy's President Kenji Sumino at the helm, the engine was fired up for the first time with its new power adder on board. No smoke, no hesitation, and in fact it sounded very close to stock at idle.
In order to hold and transfer our newfound power, we'll need a proper clutch upgrade and a wider wheel and tire set up. Also, we're going to shave a few pounds off of our roadster as well. That's all coming up in the last two episodes of 120 Hours, Super Street's Week To Wicked build-up!
