Description
AMM International is delighted to present one of the UK’s most complete and road-refined high-power GT-R builds: a 2012 Nissan GT-R Premium Edition (DBA), finished in factory Black Pearl (KH3) and transformed by JM Imports into their flagship JM1200R Signature Build. Carefully engineered, impeccably maintained, and producing a dyno-proven 1009 bhp and 911 lb-ft of torque on Shell V-Power, this extraordinary GT-R blends supercar performance with outstanding everyday usability.
Supplied new to the UK and owned by just three keepers, one of whom cherished the car for eight years, this example has always been maintained exclusively by JM Imports, one of the world’s most respected GT-R specialists. Built from a standard, accident-free DBA model with full provenance, it has covered approximately 3,500 miles since its complete JM1200R conversion in September 2022. The car remains HPI clear and is offered with two original keys, its full book pack, extensive build documentation, and the official JM Imports dyno sheet.
A testament to meticulous engineering, the JM1200R package is centred around a fully forged 3.8-litre engine designed to support power levels well in excess of 1500 bhp. CP pistons, Carrillo rods, a CNC-balanced crankshaft, JUN 264 camshafts, JM head studs, and a full OEM gasket overhaul form the blueprint of a powerplant built for absolute reliability. Paired with JM’s GT30 twin-turbo system, a race intercooler, high-flow fuelling hardware, and a Whifbitz 102mm titanium exhaust, the result is a GT-R capable of extreme performance yet remarkably composed on the road.
The drivetrain has been correspondingly upgraded to match the engine’s capabilities. A PPG 1–6 strengthened gear set, JM’s own 16-plate clutch system with Linney billet basket, extreme circlips, ETS thrust plate, and front-wheel clutch ring ensure durability under high load, while the transmission benefits from fresh Pentosin FFL4 racing fluid. The entire package is controlled by the highly sophisticated Syvecs S7 ECU with advanced all-wheel-drive logic, enhancing both traction and drivability across all conditions.
Handling and braking have been equally well addressed. TEIN adjustable coilovers provide precision and stability, while brand-new Linney brake discs, pads, and bells, combined with upgraded stainless steel brake lines, deliver exceptional stopping performance. Recent maintenance, including a full service by JM Imports in 2025, new Michelin Pilot Sport tyres, brand-new alloy wheels, and an MOT valid until July 2026, ensures the car is fully prepared for its next owner.
Visually, the GT-R presents beautifully in its original Black Pearl finish, with key impact zones protected by PPF. A Seibon carbon front splitter, Seibon carbon air duct, and Knight Racer raised rear spoiler risers lend the car an assertive yet tasteful aesthetic. Newly fitted SBD FF6 flow-formed wheels (20×10 front, 20×12 rear) complement the stance and highlight the car’s purposeful presence. The exterior is free from accident repairs or major blemishes, reflecting a life of careful ownership.
Inside, the Premium Edition’s black leather and Alcantara cabin remains in excellent condition, with clean surfaces, intact stitching, and minimal wear throughout. An upgraded audio system with subwoofer enhances everyday enjoyment, while modern additions such as a BlackVue 4K dash camera and Global Telemetrics tracker provide convenience and security.
Representing over £100,000 of professional development, this JM1200R Signature Build is far more than a high-horsepower GT-R, it is a cohesive, road-ready, expertly engineered package built for long-term durability and exceptional performance. With impeccable provenance, comprehensive maintenance, and a specification tailored by one of the world’s foremost R35 specialists, it stands as one of the finest street-focused GT-Rs available today.
