Signature Autosports has revealed Meridian 911 #001, the first car in its Signature Revival Works Meridian 911 series. The build starts with a 1989 Porsche 911 Carrera 4 and turns it into an air-cooled safari grand tourer, with an asking price of $499,950 through the company’s Wilmington, North Carolina, headquarters. The donor is a 964-generation Carrera 4, the model that introduced all-wheel drive to the production 911 and the same Type 964 platform used for Singer’s recent Louis Vuitton cars.
Meridian #001 retains the factory all-wheel-drive layout and familiar 911 shape but adds a rebuilt 3.8-liter naturally aspirated flat-six, a Russell Built Fabrication Sportsman Safari conversion, exposed carbon fiber bodywork, and a retrimmed leather and Alcantara cabin. Signature Autosports says the car has covered only testing and delivery miles since the build was completed.
The engine started as the 964’s 3.6-liter flat-six and was rebuilt to 3.8 liters with Mahle Motorsport pistons and cylinders, forged Pauter connecting rods, a forged crankshaft, ceramic-coated rod bearings, coated main bearings, upgraded head studs, and a rebuilt oil pump. Pauter Machine supplied custom billet aluminum cylinder heads with CNC-ported intake and exhaust passages, oversized valves, performance valve springs, and titanium retainers. Custom-ground Web Cam camshafts, IWIS racing timing chains, new guides and tensioners, reconditioned rocker arms on new shafts, and RSR-style sealing round out the valvetrain.
Induction comes from a Clewett Engineering individual throttle body setup under a GT3-style carbon fiber plenum with a high-flow filter. A Haltech ECU manages the engine through a custom coil-on-plug ignition system and mil-spec wiring harness. The package also includes a Clewett serpentine belt conversion, lightweight flywheel and clutch, and carbon fiber engine shrouding. Signature Autosports has not released an output figure.
The Russell Built Sportsman Safari Kit, developed from the company’s off-road 964 program, adds up to 10 inches of wheel travel, a two-inch-longer wheelbase, a wider track, and increased ground clearance. The conversion includes new suspension components, axle and CV hardware, steering parts, brake provisions, skid plates, protective panels, and purpose-built bumpers. Meridian #001 runs Eibach coil springs with King Shocks dampers, black Russell Built Baja Lite wheels, and BFGoodrich All-Terrain T/A KO3 tires.
Gloss exposed-carbon front and rear fender extensions are joined by matching carbon fiber bumpers and a carbon fiber roof panel carrying a Baja Designs auxiliary light array. Additional lighting sits at the front edge of the hood and in the front bumper, while darkened headlights and contrasting brake hardware complete the exterior.
Signature Autosports’ in-house upholstery team retrimmed the cabin in black leather and Alcantara with contrast stitching across the seats, dashboard, door panels, headliner, rear seating area, and carpeting. The custom door cards add diagonal stitching, machined aluminum details, and integrated speakers.
Rennline supplied billet dashboard controls, door hardware, gauge surrounds, pedals, and a shift knob, while a MOMO steering wheel with carbon fiber detailing sits ahead of the original five-gauge cluster. The cabin also gets heated front seats, additional sound insulation, a Kenwood digital media receiver, Rockford Fosgate speakers, Sony amplification, a compact Kenwood powered subwoofer, and a Classic Retrofit electric air conditioning system with dual condensers and an upgraded evaporator.
Future Meridian commissions will be built around each client’s choice of materials, exterior treatment, mechanical specification, and equipment.
