I promised more on this modded s202 from Minkara a few posts back belonging to Pikarin from Osaka, Japan. It packs a JUN 2.2L stroker for starters. I think this is my first J-spec subaru post as well! I’ve been on an S202 kick lately so a little background…
At 320 horsepower from the factory, the Subaru S202 was the first car to break the 276-horsepower restriction on all Japanese cars (ever notice why so many cars in Gran Turismo are “exactly” 276 hp) and paved the way for the ISF, GTR and other high horsepower creations to roll out of the island country. Every generation of Impreza has had a super limited edition sportscar model dubbed the S201 (classic GC8 ), S202 (bugeye GD), S203 (blobeye GD), S204 (hawkeye GD), and R205 (the new GRB).
The S202 essentially takes the stripped down racing model of the STI – the STI type RA spec C – and reloads it with high end sports car goodies: STI projector headlights (heavier but better looking), STI front mount oil cooler, bronze 17″ STI wheels made by RAYS (which bear a striking resemblance to RAYS Volk CE28N), chassis and brake upgrades, and a carbon fiber GT wing. Only 400 were ever made.
This guy modded an S202. He took Subaru’s ultimate bugeye and made it better, and more suited to his use for it as a weekend track car.
The metal bumper vent only on one side of the car may not be the prettiest but it is functional… behind it is a the GReddy front mount oil cooler (in addition to the STI factory front mount oil cooler that all S202′s come with), which vents air through the metal duct… pretty creative engineering.
The vents cut into the stock rear bumper (though they vary in appearance) – and the flip up rear license plate with vents behind it – are pretty standard faire on Japanese track cars. Both allow trapped air to escape the bumper and reduce drag.
The S202′s front-mount factory STI oil cooler switched positions with the intercooler.

THE JUN WRX – Jun Auto Mechanic’s “Super Lemon GDB” Bugeye
This is the JUN Super Lemon GDB.
For a time this car broke and held the lap record at Tsukuba circuit in Japan –– right when the track was making a name for itself as the proving grounds for high-horsepower creations from Japan’s top tuners. The retina scorching signature “JUN lemon yellow” paint and GTR-faced original ADVAN RG’s belie the true legacy of this car.
It wasn’t so much that it broke the record at Tsukuba – it was the way that it did it, and the Subaru vs. Mitsubishi rivalry for Tsukuba supremacy that was going on at the time. With *only* 582 horsepower and all OEM metal paneled body, the JUN WRX posted a lap time of 55.9 seconds and snatched up the title from HKS’s Mitsubishi Evo VII (56.814 second lap on Dec. 26, 2001). JUN’s record was only taken away by the Sun Auto’s Cyber Evo (55.801 seconds on Dec. 9, 2003 via Eiiji “Tarzan” Yamada) — but it took an additional 200hp over the JUN car to do so. Ten days after Sun Auto took the record, the record was broken again by the HKS Evo TRB-02 (54.739 second lap – Dec 19, 2003 via Nob Taniguchi) — a car which essentially was HKS’s old Evo VII but entirely rebodied in super lightweight carbon fiber widebody that you’d be hard pressed to find on a street car.
A similar comparison can be made to the McLaren F1’s world’s fastest production street car title only being taken away by a certain car only with an additional 400bhp (not to mention four extra cylinders, and four more turbo’s than the McLaren’s zero). OK maybe I’m exaggerating ; ) But the JUN WRX is loved among bugeye enthusiasts.
Older pics from the now-defunct Exvitermini blog (the Aussies behind the 1400-hp drag Skyline GTR-700). Don’t mind the 2003 digicam technology : P
JUN’s original-design front bumper (modified for this car with narrower center air dam to feed the v-mount intercooler/radiator and nothing else), one-off custom CF splitter purpose-built only for the JUN GDB… known to scrape perfectly level pavement in hard turns : P
WRC-style sport mirrors likely made by STI for the GC8-chassis Impreza and adapted to the JUN GDB.
Stock WRX reflector headlights (lighter weight than the JDM projectors and stock on the STI Spec C) with JUN original-design eyelids. GTR-faced Advan RG’s housing giant Endless big brakes and Zeal Function-SPL coilovers.
Hood with custom-cut vents for the V-mount intercooler (not a WRC drop-in hood vent despite similar look)… and cowl by the windshield likely to vent heat from the massive turbo setup. The hood eventually received NACA vents (see last pic).
Custom turbo location against the firewall with meticulously welded titanium turbo inlet piping. Split intake manifold with two gigantic surgetanks atop a 2.5L JUN stroker kit on a 2.0L EJ207 (this was before the EJ257 existed). Dual-core V-mount intercooler setup. JUN’s trademark green-to-yellow fade painted timing belt cover.
You may have seen the video of the white JUN GC8 setting a top speed run. That car was owned by a customer, this car was owned by JUN itself and allowed the company to flex its engineering might and be even more creative.
SARD GT wing with custom covered mounts (not unlike the Mugen wing for RSX’s) mounted on the chassis itself as opposed to the trunk… and JDM STI rain visors. A nice “street car” touch on this track beast.
…and an enormous one-off rear diffuser purpose built for the JUN Car with integrated rear bumper vents. Closest thing you can buy for a bugeye outright is the Mature diffuser but even that is dwarfed by the JUN race piece.
