HJA is thrilled to present this special edition Subaru WRX STi Spec.C, expertly tuned by the world-renowned JUN Auto Mechanic from Japan. The car is incredibly fun to drive, especially on A and B roads, handling like it's on rails. With 418bhp at the wheels, it certainly gets going very quickly!


JUN Performance specializes in manufacturing a wide range of high-performance, high-quality engine parts for Japanese vehicles. JUN has built its reputation through competing in numerous race categories, including drag racing, top speed events like the Bonneville Speed Trial, and circuit racing.


Under the hood, this beast is equipped with a JUN 2.2L Stroker kit, which includes a long-stroke crankshaft and JUN forged aluminium pistons crafted by Cosworth. This upgrade boosts power and torque capabilities, featuring lightweight, high-strength, and balanced parts for enhanced response. Its reinforced design ensures it's suitable for street driving, circuit racing, drag racing, and more.

The addition of an HKS GT-RS turbo and HKS cams makes it versatile, offering exceptional response, torque, and top-end power for everything from city cruising to time attacks.

The intake and exhaust systems have been meticulously tuned, featuring a Trust intercooler, HKS exhaust manifold, HKS sports catalytic converter, and a stealthy HKS titanium muffler that sounds incredible when on boost!


Cooling is managed by a Trust aluminium radiator and Trust intercooler, ensuring optimal engine temperatures even during spirited driving.


The drivetrain is enhanced with an HKS LA clutch, Cusco LSD, and Prodrive coilovers, providing superb manoeuvrability and a nimble, flyweight-like feel on the road. The Endless front callipers offer confidence-inspiring braking at any speed.

The exterior maintains its classic appeal with the addition of a genuine front spoiler and an aftermarket bonnet duct. The car rides on Rays Volk Racing CE28 wheels, which perfectly complement its design and colour.


Inside, the interior remains mostly original. The steering wheel has been upgraded to a MOMO, and additional Defi gauges (boost, water temperature, oil pressure) have been installed, ensuring you can enjoy sporty driving with complete peace of mind.

The chassis is in fantastic condition, as evidenced by the underside photos, and key areas have been protected.


We cannot stress enough how rare it is to find Impreza’s with this specification in Japan these days. Due to the global demand for these Japanese icons, prices are continuously rising. After closely monitoring the market over the past few years, we can assure you there is no indication that prices will come down. Most Japanese owners, whether private, dealers, or tuning shops, are holding onto their stock as these cars have become appreciating classics.
