Delivered new to Germany in 1977, this Porsche 911 2.7 MFI would later be sourced and imported to the UK by experienced Porsche racer Des Winks. This example had been carefully selected from single ownership due to the excellent condition of the bodyshell. During the early 90s, the car would be converted to 2.7 RS Lightweight specification with the intention of using it for competition. Work included new steel front and rear wings and Kevlar bumpers, bonnet and duck-tail whilst inside the 911 was fitted with full Safety Devices front and rear cage and full lightweight interior trim. Preparation was undertaken by Bob Watson including rebuilding the engine and gearbox to 210bhp, 2.7RS-specification with genuine steel RSL rear trailing arms, RSL brakes and Bilstein suspension to run in the 1993 Pirelli Porsche series. In 1995, the car was sold to Steve Rogers and subsequently in 2004 to Mike Nesbit. Around 2006, the car was fitted with a 993, 3.6-litre engine before competing in the Scottish Classic Sports & Saloons. The Porsche was particularly effective with Mike setting a new track record at Knockhill in 2007.

Our vendor, Motorbase Performance, purchased this 911 in 2018 as a project to showcase the standard of workmanship achievable in their newly established Classic Performance department. Motorbase Performance are a UK-based race team with many years of experience and success within the industry including 2010 Porsche Carrera Cup Champions and 2014 British GT Champions.

Despite having recently received £30,000+ in attention (mainly from Porsche specialist Tech9), the decision was taken to disassemble the old racer and rebuilt it from the ground up in-house at their motorsport facility near Brands Hatch. Photographs and invoices within the file show the shell stripped and rebuilt using genuine heritage parts and panels purchased from Porsche GB. All mechanical parts were stripped and rebuilt where necessary and all electrical items checked and repaired as required. The shell was then professionally finished inside and out by their expert paint-shop in a stunning shade of grey before reassembly. The suspension geometry, including the Bilstein dampers, was set-up correctly for fast-road or race use. The interior was enhanced with a new set of Corbeau race seats and the exterior finished with new genuine headlamps and 16” Fuchs alloys (a set of 15” wheels and tyres accompany the car for track-day use). Also accompanying the car is a substantial history file including the aforementioned restoration documents, detailed history back to the cars import in 1989, current V5 and current MOT Certificate valid until July 2012.

Since completion, the car has had light use and has been on display at Porsche Carrera Cup GB and Silverstone Classic events for Motorbase to showcase their Classic Performance department. In summary, this very special Porsche 911 has been lovingly restored by one of the UK’s best-known racing teams using original parts and utilising many years of motorsport knowledge and experience. Built for fast-road, track-day or full competition use this is a very cool versatile classic 911 with current Supercar performance.

Viewing of this cracking 911 is highly recommended and, as you would expect, the car fires into life on the first turn of the key, sounds amazing and is described as performing extremely well.
