The car is an interpretation of a sports road racing car from the early 70’s – if Porsche had chosen an open cockpit 911 format. Design cues were taken from 356 speedster, 550 Spyder and various European cars raced in sports car classes including SCCA, IMSA and other period series.
The basis of the car is a 1971 911 targa, chosen as it was originally an open top car. Regardless, the body shell was strengthened during restoration, primarily in the sills and B pillar area. The original (sheet metal) targa hoop structure was removed and replaced with a 60’s/70’s style roll hoop braced to the sills, B pillar and rear suspension areas. The roof hoop was designed and installed by an experienced motorsports fabricator, and also incorporates seat belt mounts. The upper windscreen surround has been deleted, with the lower windscreen channel retained to locate and support a small aero screen. The door glass openings have been deleted along with the door handles. The door interiors are inspired by those of the 550 Spyder.
The rear bodywork has been lowered and also further declined to provide a smoother transition to the door line. The engine cover has been similarly modified. This provides a lower rear bodywork line more akin to a 356 speedster than say a 911 targa or 911 speedster.
All bumpers are standard and all bright work and exterior trims have been retained for an “ex-factory” style appearance. The colour is Signal Orange, which was a standard colour available in 71.
The Lexan aero screen includes 2 wind deflectors that can be independently mounted in low (flush), mid or high positions depending on driver height and intended use. This was something used by several open race cars in the relevant period and they are very effective at calming wind buffeting etc. The necessary tools to adjust the deflectors are provided in a leather pouch in the glovebox. Spare screens come with the car as well as a cutting template. The screen profile is very easy to modify to taste.
Interior
The interior has been fully retrimmed using correct era Hargann carpet applied over modern insulation. The seats are 911R style in black leather with Porsche “Jubilee” fabric inserts (blue with a small hint of orange). This fabric also appears in the (550 Spyder styled) door openings.
The dash has been significantly simplified with all holes closed to enable a painted finish (again referencing 356 speedster, 550 Spyder). A gauge mounting fascia was fabricated to mount 3 gauges, as per early 912 dashes. However, the original 5 mounting holes are retained under the plate should a stock 5 gauge setup be desired. A motorsports battery kill switch has been added to the fascia, handy for both security and isolating the battery between drives.
A full length, split tonneau cover is also fitted, with a central zip enabling a single (driver) or dual (driver/passenger) format. The tonneau is made from early 70’s Porsche targa top material.
Mechanical
The engine has been rebuilt with capacity increased 2.4 litres and features S cams, new PMO carburettors, SSI exhaust system and MSD ignition. The engine has been tuned on a rolling road dyno and produced 190hp.
The gearbox is a 901 type 5 speed (aka dog leg) with the desirable 7:31 ring and pinion. A modern Rennshifter has been fitted to improve shift accuracy and ease of use (hidden by a factory rubber boot).
Brakes are S type alloy calipers and have been rebuilt. Suspension is also rebuilt with Bilstein shock absorbers, larger torsion bars and adjustable front and rear anti roll bars.
The wheels are custom made 15×7 steelies with 205/60 tyres on all corners. The fuel tank has been converted to under bonnet centre fill. The car has also been rewired and uses modern blade style fuses.
Driving experience
At 190hp and only circa 900 kilograms the car is quick, and feels even quicker given the open cockpit. It is exceptionally fun to drive, even at moderate speeds. Given the lack of a rear screen, the induction noise is unlike any other 911 I have owned. The car has done about 3000kms since the rebuild and restoration and thus everything feels tight and new.
