The vehicle in detail

Engine: Earlier in its life the original matching number engine #63S80511 suffered a bearing failure which destroyed the case, a common occurrence with the 993 Cup’s due to their more narrow rod journal compared to the 964’s. A correct M64/70 factory 993 cup engine serial number 63S80508 was sourced from Germany and it turned out to be only 3 digits off from the original engine. Ollie’s in Arizona did the machine work on the case and the engine was completely rebuilt to factory specs by Todd Ketchum, long time IMSA Porsche mechanic. The only deviation from stock 993 Cup spec was the replacement of the oil pump with the later 996 GT3 high output oil pump, which helps to prevent bearing damaged that occurred with the original engine.  Additionally the solid rocker setup with shims was replaced with adjustable rockers. Oil coolers were flushed and soda blasted. Oil tank was flushed. Correct cup Motronic ECU is retained. Spark plugs and wires are new. Fan repainted the correct Zermatt Silver. Engine tins were powder coated. Factory motorsport headers retained. Single O2 sensor catalytic converter was cut open to remove clogged cats and rewelded to retain the factory look. Non-original exhaust tips were replaced with reproductions made to match the factory cup pieces which are NLA.  All the factory heat shielding is in place and correct for the 993 cup. New fuel filter and fuel pump.

Drivetrain: The transmission was completely rebuilt to factory cup specs by Cory Friedman of Autometrics in Charleston, South Carolina, new bearings, motorsport synchros, etc. Factory cup gear ratios were retained.  Clutch master cylinder and slave cylinder are new.  CV axles were rebuilt by CV source in Atlanta Georgia. Stub axles are new front and rear. All 4 wheel bearings are new. Correct Speedline Magnesium Supercup wheels were completely refurbished. Outer rims retain the original “Speedline for Porsche” etching.  Speedline wheel bolts were re-chromed. Magnesium centers were soda blasted, inspected for cracks, and repainted in speed yellow. 1995 date codes on the wheels. Brand new Pirelli rain tires.

Brake system: All 4 brake calipers were rebuilt and repainted by PMB performance in Utah. New PFC 97 compound pads installed with new OE brake discs.  All ABS wheel sensors are new. Most brake lines are new. ABS pump was replaced with new unit. Correct cup ABS ecu is fully functional.

Suspension: Bilstein dampers were rebuilt to Cup specs by PSI Shock in Petaluma, California. Suspension coil springs were replaced with slightly softer than Cup spec, 180 front and 200 rear. Factory GT2 Evo uprights retained.  Front and rear sway bars were powder coated. Suspension subframe and suspension arms were inspected and soda blasted, anything out of spec was replaced. Steering rack was rebuilt by The Rack Doctor in South Carolina.

Body: Single stage urethane paint, body is black L741 and bumpers/fenders are speed yellow X4. Paint readings available. Front and rear bumpers along with the side skirts and splitter are all brand new urethane plastic factory pieces, no fiberglass aftermarket components on this car. The front splitter is traditionally a weak point with the 993 cups, so extra bolts were added and special flaring nut-serts were used to fix the metal reinforcement strip to the splitter/lower bumper. The tail/wing is the correct cup tail produced by Turnwald serial number 06347.  The doors are correct for the 993 cup with no internal door bars.  Correct 993 cup aluminum hood is retained with cup hood prop. Windshield washer system is fully functional.  Graphics were reprinted to match the 1996 Supercup season livery.  Adobe illustrator files come with the car.  Xpel paint protection film on the front fenders, hood, front bumper, and splitter.

Interior: Door glass is the correct thinner 3mm, not like the 5mm glass on the street cars.  Rear glass is also the correct thinner cup style without the heating element, very expensive if you need to replace it. The air jack system was completely overhauled by Cup Car Solutions, with a new ergovent and new air jacks. Correct cup MOMO Porsche steering wheel with exceedingly rare Supercup horn button (non-functional).  Seat brackets are correct cup Recaro pieces with offset design to bring the driver closer to the center of the car. 2 Recaro SPG Profile seats, one original Porsche seat with 1995 date code and one new. One original Sabelt 6-point harness from 1995 and one new Sabelt harness. Exceedingly rare original Werner cup fire extinguisher is retained.

Electrical: With Porsche’s history of wiring harness failures on the 993’s, it was decided to completely remove the wiring harness from the car, unwrap for inspection, cleaning, refurbishment and rewrapping.  Any aftermarket wiring additions like cool suit, radios, etc were removed and taken back to stock cup spec.  Engine harness was replaced with a new factory unit as a precautionary measure as well. All fuses replaced. All lighting is functional including back up lights and the correct EU headlights and turn signals. New battery with addition of a battery strap for added safety.

A successful shakedown race was completed at Sebring with HSR in Dec. 2021.  2 hours of runtime.
