1998 Nissan 180SX S13 “RYO Demo Car”
2.1L SR20DET 5-Speed Manual
MOT: 12 Months on arrival
Current Mileage: 74,415km
This 1998 Nissan 180SX S13 Type X “RYO Demo Car” is a no-compromise showcase build, developed in Japan and completed in 2019 as an official R.Y.O. demo vehicle. Finished in striking red following a full colour change from white, this sunroof-equipped Type X benefits from widened arches, a full aero package, and extensive chassis preparation including a stitch-welded engine bay. With just 74,415 km, a fresh 12-month MOT on arrival, and a documented history from Japan, this is a rare opportunity to acquire a genuine show-proven S-chassis with serious pedigree.
At its core is a formidable 2.1L stroked SR20DET, built using a high-end HKS stroker kit and forged internals, paired with Tomei PonCam camshafts and a TD06-24G turbocharger. Supporting modifications include a Greddy inlet manifold, GCG exhaust manifold, upgraded fuel system with Radium components, and comprehensive cooling via HPI and Trust hardware. Engine management is handled by an HKS F-Con V-Pro ECU with electronic boost control, delivering a verified 486 PS (480 BHP). The result is an exceptionally responsive, high-output SR setup designed for both reliability and outright performance.
Inside, the car reflects its demo status with a fully custom one-off Okuyama (Carbing) 18-piece roll cage, finished in candy red and integrated seamlessly into the cabin. Driver focus is enhanced through a Haltech digital dash, Nardi steering wheel with Work Bell quick release, and a pair of Bride ZIEG III Low Max bucket seats, complemented by matching Bride interior trims. Additional motorsport touches include an aluminium battery relocation box and discreet functional electronics, creating a cockpit that balances visual impact with genuine usability.
Performance is matched by a comprehensively upgraded chassis and drivetrain. Suspension duties are handled by Racing Gear Formula coilovers with a full suite of Ikeya Formula arms and a modified S14/S15 rear subframe, while stopping power comes from Ferrari F40 front Brembos and R33 GT-R rear Brembos. A 5-stud conversion supports Rays TE37 SAGA wheels on Yokohama tyres. Power is transmitted through a rare Nismo 6-speed gearbox, Nismo LSD, twin-plate clutch, and lightweight flywheel. Formerly displayed at the 2019 Nismo Festival at Fuji Speedway, this car represents a standout example of a professionally built, historically significant S13 demo machine.
Possibly the best looking 180SX we have ever sold!
