1970 Porsche 914/6 GT
- Engine
- 2.0L flat-six Carrera 6 unit, twin-plug ignition, ~212 bhp
- Colour
- Tangerine with Ecurie Biennoise racing livery

Chassis 32 is the first of sixteen factory-prepared Porsche 914/6 GT examples built in 1970, delivered new to Gustav Schlup of the Swiss Ecurie Biennoise racing team. It competed across thirteen European races in 1970–71 under Schlup, then passed to Jean Baptiste Canonica for the 1972 European GT Championship season. After acquisition by its long-term German custodian in 1980, the car underwent bodywork repair and spent decades in careful private ownership. A comprehensive restoration completed in March 2021 returned it to period Tangerine livery with Ecurie Biennoise markings, and the original 2.0-litre Carrera 6 engine was fully rebuilt to factory specification.

Maintenance & restoration
- 1980Bodywork
After acquisition, the chassis was stripped to bare metal and repainted in Guards Red; minor racing damage, primarily to the front left, was identified and repaired at the same time.
Historic photographs on file document the damage and the repair process, as well as structural features confirming factory-prepared provenance.
- 1980Modification
The original 2.0-litre Carrera 6 race engine was removed and placed in dry storage; a 2.7-litre 911/83 unit sourced from a Carrera RS was installed in its place.
The substituted engine allowed the car to be used sparingly on the road while preserving the original competition unit.
- 2020Engine rebuildBSM Salewsky
The original 2.0-litre Carrera 6 engine, recovered after roughly two decades in external storage, was completely overhauled and returned to factory specification by an air-cooled Porsche specialist.
The engine had remained undisturbed on its storage pallet since 1980; specialist workshop is located in Eupen, Belgium.
- 2021Restoration
Comprehensive restoration completed, returning the exterior to the period-correct Tangerine colour with Ecurie Biennoise racing livery reinstated.
Restoration encompassed both cosmetic and mechanical elements; completed March 2021.
