This 1965 Honda S600 was reportedly imported into Australia in the 1970s and modified during previous ownership between 2005 and 2008. Work included a repaint in blue and the installation of a Kawasaki 1,200cc inline-four paired with a 6-speed sequential manual gearbox and Mazda Miata 4.3:1 limited-slip differential. Other modifications include Miata suspension and braking components, adjustable Gaz dampers, a Quaife reverse gearbox, Cobra seats, and a Kawasaki Ninja instrument panel. The car was purchased in 2016 by the seller, who imported it into California in 2019. This S600 is now offered with partial service records, importation documents, and a clean California title in the seller’s name.

During a refurbishment performed between 2005 and 2008 in Australia, the car reportedly was stripped and repainted in Subaru World Rally Blue. Other work included re-chroming of the bumpers, grille, and headlight surrounds, and new chrome windshield trim was installed at that time as well. The car features a fiberglass hood and trunk lid, and the seller reports that the mounting points for the roof have been removed along with the window mechanisms and glass.

According to the seller, the car is equipped with the narrowed rear subframe from a Mazda Miata, as well as the donor Miata’s front subframe and suspension, 4-wheel slotted and vented brake rotors, brake booster, brake master cylinder, and front wheel hubs. 14″ SSR Mk II wheels were added by the seller and wear Federal tires. Height-adjustable coilover Gaz dampers are fitted at the corners, and the front torsion bars have been removed.

The right-hand-drive cabin features Cobra seats trimmed in black leather, a roll bar, and a refurbished dashboard containing a Kawasaki Ninja instrument panel, which includes a 13k-rpm tachometer and a 350-km/h speedometer.

Other equipment includes a MOMO steering wheel, a fire extinguisher mounted in front of the passenger seat, a SpeedoHealer speedometer calibrator, and a gear selector indicator. The digital odometer shows just under 15k kilometers (~9k miles), 600 of which were added by the seller. Total mileage is unknown.

The 1,200cc inline-four is reportedly from a Kawasaki Ninja ZX-12R motorcycle and was installed between 2005 and 2008. Power is routed to the rear wheels through the bike’s 6-speed sequential manual gearbox and a Mazda Miata 4.3:1 limited-slip differential. Other equipment includes ceramic-coated exhaust headers, a 2.5″ oval aluminum exhaust from Gonzo’s Racing Pipes of Australia, a Quaife reverse gearbox, hardened race axles, an aluminum radiator, and a Muzzys billet clutch. Maintenance in 2019 consisted of a coolant change as well as an oil and filter change.

The car is equipped with four heavy-duty driveshaft loops, and additional photos of the underside and suspension are presented in the gallery below.

Importation documents and partial service records are included in the sale.
