Seller's Notes

This Porsche 911 SC is a stylish and engaging modern classic sports car, which was extensively rebuilt in the 1990s into an attention-grabbing open-top 964-era Turbo evocation. Under the rear engine lid sits a highly upgraded 3.0-litre naturally aspirated twin-spark flat-six, delivering around 157kW to the rear wheels via a five-speed manual transmission. This example started life as a US-delivered 1978 911 SC model, which underwent its extensive rebuild in the 1990s, before it was imported and first registered in Australia in around January 1999. The car has only recently been acquired by the seller. The odometer shows 103,962 Kms. This 911 SC was transformed into an eye-catching open-top 964-generation Turbo evocation, which included the original coupe model being professionally converted into a right-hand drive cabriolet, and the fitment of sheet steel 3.2 Turbo-style front and rear wheel arches, which were genuine Porsche components welded to various locations in accordance with Porsche instructions, and all engineering approval was subjected to an official conversion assessment. Further bodywork modifications included the removal of the rear seats, a custom Speedster-style double roll bar setup fitted to the rear cabin, a widened track with larger wheels configured to fit the widebody conversion, the fitment of 964-era Turbo front and rear bumpers, the front fog lights replaced with RS-style air ducts, a 964-era ‘whale tail’ rear spoiler being fitted, and a genuine Porsche convertible roof being installed. This example is now finished in the stylish shade of Midnight Blue with a black convertible roof, over a black leather-trimmed interior. It rides on a set of 18-inch Porsche Cup Kerscher Speedline five-spoke split-rim alloy wheels finished in silver with polished barrels, and fitted with Falken Ziex tyres. Equipment includes a four-spoke steering wheel, white dials, a Kenwood stereo with Bluetooth connectivity, USB and auxiliary inputs, air conditioning, and electric windows. Further upgrades include Rockford Fosgate speakers with a hidden under-seat subwoofer, a high-compression 3.0-litre flat-six engine, a sports cam, a twin-spark setup with coil packs, an EFI conversion, a ceramic-coated exhaust system, and a high-torque starter motor. The car comes with a folder containing an extensive collection of maintenance invoices dating back to the late 1990s. Please refer to the photo gallery to assess the exterior and interior condition. Specific notes from the seller include: the car is believed to have been repainted in 2016, there are some minor paint blemishes on the front bumper from stone chips and scraping underneath, a small blemish on the right-hand rear wheel arch, the odd age-related imperfection, slight creasing and wear on the leather upholstery, and the carpet is showing signs of wear. This 911’s most recent maintenance was carried out in May 2024 at 103,850 Kms by JJ’s Garage, which consisted of a safety inspection, and all the fluids being topped-up as required. A minor service was performed in October 2022 at 84,956 Kms by Hoskin & Hoskin Pty Limited, which included an engine oil and filter change, and a full inspection. The engine was fully rebuilt in 2021 by Promotive Engineering in Brisbane, which cost around A$50,000. Other notable maintenance includes a new air conditioning compressor and drier being installed, an air conditioning re-gas, the gearbox being partially rebuilt in 2021, the gearbox and engine oils being changed in February 2024, a full ECU retune in March 2024, and two new tyres being fitted in June 2024 This Porsche 911 SC is a rewarding and desirable classic air-cooled sports car, which was extensively rebuilt in the 1990s into an attention-grabbing open-top 964-era Turbo evocation. Now presented with an appealing Midnight Blue finish, a commanding widebody conversion, a focused two-seater cabin, and boasting a potent turbocharged flat-six engine coupled to an engaging five-speed manual gearbox, it would make a stand-out addition to any collection, and a stylish and exciting companion for weekend drives, fair-weather cruising, and classic car show visits alike.
