Modifica Classica | 1989 Porsche 911 3.8L C4 Outlaw RS Tribute | MC009
Acquired in July, 2025 from the previous custodian who owned the car for over 24 years, with the goal of adding tasteful modifications as an RS Outlaw tribute. This Stone Grey Metallic 964 is accident free in mostly original paint, as shown in gallery in Porsche color code 693. This 911 964 Carrera 4 carries it’s original flat-six engine that has been bored to 3.8L RSR displacement by renowned air-cooled performance specialists SHK in Hungen, Germany. Paired with it’s original rebuilt G50 5-speed manual transmission and Steve Wong performance chip.
Spark plugs were replaced in April, 2025 along with the blower air duct. An engine out service was completed in Germany in June, 2025 prior to importing to the US with cylinder heads disassembled, blasted and overhauled, as well as renewed exhaust guides, valves ground and re-lapped, and cylinder heads reassembled with new valve springs, new valve cover gaskets, as well as a new SACHS clutch kit.
Upon importing the car to the US in July, 2025, additional service by renowned KMW Motorsports in South Florida including new front and rear brake rotors and pads, brake fluid, oil change and oil filter, new power steering hose, and a new battery. The CCU unit has also been rebuilt and is said to blow ice cold air-condition.
Tasteful modifications include heated Recaro Sportster CS Napa leather seats, updated aero mirrors, RS-style body components including front RS style air ducts, a 991 GT3 center exhaust, Fabspeed RSR high performance headers, a MOMO mod 07 style Porsche design genuine black napa leather steering wheel, BBS E88 motorsport wheels with polished barrels and BBS gold centers, Bilstein RS style coil-overs engineered for street use and fully adjustable, and a host of other upgrades and refurbishments and an entirely updated interior.
This one-of-a-kind 964 is now being offered by its seller with a clean title in Montana showing 201,760km equating to 125,368 miles.
Power comes from the original modified air-cooled M64 flat-six engine, now bored out to 3.8L with 3.8L RSR cams & cylinders. The motor was entirely rebuilt in January, 1996 with 118,068 km equivalent to 73,364 miles. The work was undertaken by reputable air-cooled performance and racing specialist SHK in Germany with 3.8L RSR 103mm cylinder case and 103mm pistons along with 964 RS camshafts. The car has since received a major engine out service with top end rebuild and new clutch in June, 2025 in Germany.
The engine breathes through an upgraded 991 GT3 exhaust system with Fabspeed RSR headers and sends power to all four wheels by way of a 5-speed G50 manual gearbox with a new Sachs clutch kit.
Exterior aesthetic updates include a center outlet 991 GT3 exhaust with the right side outlet filled on bumper, front bumper Euro detent deleted for an ultra smooth finish, RS-style air ducts in the front bumper, updated aero mirrors, and BBS E88 motorsport wheels dressed in Toyo Proxes R1R-SL tires measuring 225/40 ZR18 in front and 265/35 ZR18 in rear.
The cabin has been tastefully modified and updated featuring black Napa Leather Recaro Sportster CS Seats with heat, and a Momo Genuine Porsche deep concave matte black steering wheel with black napa leather. The Recaro Sportster CS seats save approximately 39lbs over the original seats, with the Fabspeed RSR headers and GT3 center outlet exhaust saving another 43lbs in weight, overall estimated weight savings of over 80lbs. Additional equipment includes a Function First black anodized shift knob, Rennline interior trim components such as black anodized perforated interior door handles, black anodized ignition switch bezel, and matte black phone mount. For audiophiles, a Blaupunkt Bremen SQR Bluetooth radio finishes off the cabin acoustics.
A true driving enthusiast's car with tasteful, thoughtful, and methodically appointed details. Vehicle includes clean Montana title, along with the original German title and binder with extensive documented invoices including the 3.8L documentation from SHK & maintenance records and a fully detailed excel sheet of the build by Modifica Classica including all restoration and modifications since acquiring the car. Also includes original German documentation from the previous owner regarding the 3.8L piston and cylinder conversion on this 1991 964 Carrera 4. The car absolutely rips and has to be one of the fastest most engaging 964 driver’s cars I have ever owned and built.
