If you’ve been around the block for a while, you’ll know that one of the main complaints on the OG Hachiroku twins was that it lacked power. That is why forced induction systems, such as turbochargers and superchargers, were common modifications for the Toyota 86/Subaru BRZ over the past 10 years or so.

So naturally, when the all-new GR86 was unveiled earlier this year, the first thing that Toyota had to upgrade was the powertrain – which they did. The boxer engine underneath the hood now displaces 2.4 litres instead of two, and the output was bumped up to 235 hp and 250 Nm.

But what the new Toyota GR86 doesn’t come with, are turbo and supercharger kits. So just as the saying “haters gonna hate, tuners gonna tune” goes, aftermarket specialists immediately went to work on the new car – and within just a couple of months, already have something to show at the “Fuji 86 Style” event at the Fuji Speedway last Sunday.

The first of the bunch of force-fed Hachiroku is called the “GR86 Concept GReddy Version”, going with the turbocharger route. Paired to the 2.4-litre Boxer engine is GReddy’s T620Z RX turbocharger, which – from the model number – looks like an updated version of the one offered with the previous 86.

The Japanese tuner did not reveal any performance numbers, but based on their previous work with the 86, it’s safe to assume the new tuned GR86 will make upwards of 300 hp and 350 Nm of torque. Supporting the extra power are the new engine oil cooler, a Power Extreme 3 exhaust muffler, as well as a significantly larger brake system with six-pot front and four-pot rear callipers.

To complement the additional performance, GReddy also developed a new suit of carbon fibre armour in partnership with Voltex, consisting of a new front splitter, side skirts, rear diffuser, and a “GT-style” rear wing. The exterior modifications are capped off by a set of 18-inch eight-spoke Volk Racing NE24 wheels.

Meanwhile, Japanese rivals HKS went the other direction with a supercharger kit for the new Toyota GR86. By equipping the car with what it calls the GT2 Supercharger System, HKS says their tuned GR86 will make around the region of 340 hp, but did not reveal any torque figures.

Of course, to support that much extra power, HKS also had to fit a new engine oil cooler, ECU, and a LA twin-plate clutch underneath the bonnet. To take it to the next level, the show car was also fitted with the brand’s Hi-Power Spec L II lightweight exhaust system, as well as the Hipermax S adjustable suspensions – which the company says calls it “the best ride in HKS suspension history”.

For bodywork, the HKS Toyota GR86 Concept is decked out in dramatic carbon fibre parts, including new front splitter, canards, side skirts, rear lower spoiler elements, a ducktail spoiler, plus a massive rear wing at the back. To tie it all up, HKS also included a set of Yokohama Advan Racing GT wheels.

Both of these cars are still very much in their development phase, so there aren’t any pricing and availability information just yet. It does serve as a tantalising preview to what these aftermarket tuners can do, but the question is, do you really need that much more power?
