This car was acquired by Peter Pearce in 1985. It came equipped as a Carrera GT Speedster, although it was not shipped from the factory in that guise (Serial # 82865).
The engine is a Type 547/5, which is the last of the roller crankshaft Furhmann 4cam engine series. It was the type of engine used in the Type 718 RSK and RS 60/61 Series Porsche Spyders.
The rebuilt engine includes a new remanufactured roller crankshaft from Karl Hloch in Germany, and verified by Adrian Gang at Edelweiss Porschaus.
The newly rebuilt engine includes, in addition to the new roller crankshaft, new pistons and cylinders, new valves, and many other new parts. All parts are either new or completely restored.
The crankcase was refreshed with machining done be Ross Cummings at Phil Riley & Co., including line boring.
The car is a true dual-purpose sports car, which can be set up in full street trim or competition configuration.
The interior has also been refreshed with newly upholstered Speedster seats with corduroy inserts also by Autos International.
When set-up for competition the car windshield is removed and a full bespoke aluminum tonneau is installed with an integral head fairing and wraparound racing screen.
Hidden under the tonneau is a bespoke removable triangulated roll-cage designed by Pearce, and made from chrome-moly steel tubing. Pearce designed and built the structures of Biosphere 2 in Arizona, and is an authority on three-dimensional space truss design and engineering.
This triangulated system not only provides roll-over protection but also adds significantly to the beam adding torsional stiffness. These structural attributes contribute significantly to improved cornering performance.
Cornering performance and directional stability are also improved by reinforced front suspension components with optimized camber and caster geometries.
The car is fitted with an oversize front anti-sway bar and Koni shocks at all four wheels.
The combination of the stiffer chassis and the aforementioned suspension refinements the car exhibits remarkably neutral handling.
The car is fitted with AVON radial tires of correct vintage dimensions.
Another enhancement that contributes to the cars neutral handling is that it is equipped with an authentic vintage ZF limited slip differential, which works perfectly.
Brakes are from the Porsche Type 718 RSK Spyder competition car. All brake lines are stainless steel.
Other performance enhancements include two external oil coolers mounted in each of the front fenders behind the horn grills. The coolers are controlled by a Porsche factory 904 thermostat.
The car currently has a stock 356 fuel tank installed but a GT style fuel cell comes with the car.
The car has been converted to a 12-volt electrical system along with an electronic ignition system.
For safety reasons and to protect the car from rust caused by spilled battery acid, the 12-volt battery is installed in a fully enclosed marine style battery box that is securely mounted to the vehicle bodywork.
The car was the object of a fully stripped to bare metal restoration and is 100% rust free. The silver paint was refreshed recently as was the interior.
