This 1988 Porsche 930 Turbo Coupe is finished in Black over a Champagne Beige and Black special leather interior with optional power-adjustable supple leather seats. The car was reportedly under the care of its second owner since 1988 and had been sitting for 18 years when it was purchased by the current owner in June 2023. This 930 has since undergone nearly $100k worth of service and upgrades, including a rebuilt 3.4-liter engine with 8:1 compression, forged pistons, ported and polished heads, aggressive 911SC cams, European-spec fuel injectors, a modified K27 turbocharger, a RarlyL8 intercooler, and a stainless-steel exhaust system. It also features overhauled brakes, new suspension with Bilstein B6 shocks and strut inserts, a bump-steer kit, Turbo tie rods, and a sport clutch. Modified for increased performance while preserving its original appearance, this 3.4-powered 930 Turbo is now being offered for auction out of Georgia with approximately 57k miles showing on the odometer.

One of the most iconic sports cars of all time, the 930 Turbo is characterized by its wider fenders and “Tea Tray” rear spoiler. This Coupe is finished in Black, and the seller states the paint is in excellent original condition. Equipment includes headlamp washers, integrated fog lights, a front chin spoiler, heated power mirrors, an electric sunroof, a rear window wiper, rear fender stone guard decals, and 16” Fuchs forged alloy wheels. The car rides on Bridgestone Potenza Sport tires showing 2022 production date codes. Additional images, paint meter readings, and a clean CARFAX report can be found in the gallery.

The cabin is appointed with Champagne Beige and Black leather upholstery, including optional power-adjustable supple leather seats with driver’s side lumbar support. It features a black leather four-spoke steering wheel, power windows and door locks, white instrument dials, a central tachometer with an integrated boost gauge, Turbo-logo floor mats, air conditioning, a Continental Bluetooth head unit, and upgraded aftermarket speakers.

In 2024, the car’s original 3.3-liter flat-six engine was rebuilt to a 3.4-liter displacement with 8:1 compression forged pistons and liners, ported and polished heads, new valves and springs with titanium retainers, aggressive Webcam 911SC cams, new rocker arms, European-spec fuel injectors, and an enhanced fuel distributor. It features a RarlyL8 upgraded K27 turbocharger (14.7psi), blow-off valve, intercooler, and a stainless-steel exhaust system. The rear wheels are driven through a 4-speed manual transaxle with an upgraded sport clutch. The seller notes the brakes have been overhauled and the suspension was completely refreshed, including new Bilstein B6 shocks and strut inserts, strut mounts, ball joints, wheel bearings, Turbo tie rods, and a bump-steer kit.

This sale will include owner’s manuals, a window sticker, and a clean title.

 

The seller would like you to know: “This 1988 Porsche 930 Turbo was purchased by a close client and friend of Car Concierge. He is known for his attention to detail and meticulous care of the cars in his collection. As a professional, he owns and operates a high-end service shop focusing on the service and restoration of Porsche, BMW, and Ferrari. When the current owner purchased the 930 Turbo, it had been sitting for 18 years. That owner purchased it directly from the first owner, who had only had the car for three months before selling. Once the 930 Turbo was brought home, the in-house 911 expert built it up with no expense spared. With almost $100,000 invested, this 930 Turbo is ready to go, and you will not find a more sorted example. Since the work was performed, the current owner has only put 500 miles on the car. This vehicle includes two keys, a clean Carfax, no accident history, and is in absolutely concours condition. Additionally, the sale comes complete with the factory Porsche parts. This 930 Turbo has been meticulously maintained and mechanically refreshed by the current owner’s high-end service and restoration shop and is ready to provide its next owner with an unparalleled driving experience. With a rich history in the automotive world and timeless looks, this 930 Turbo is ready for the local concourse, switchbacks, or weekend coffee cruise.”

    Can we get a video of that RarlyL8 exhaust? Thanks.

    @Galevin We haven't run the car on a dyno so it is hard to say. At least 400HP crank.

    @Reline7500 The Fuel system is a euro 930 fuel distributor and a euro WUR ( warm up regulator) with Euro fuel injectors. All modified by RarlyL8 for high performance. The 930 is also running a full exhaust and heater boxes by RarlyL8.

    It has a K27/k29 hybrid turbo running one bar Tial waste gate

    Ported and polished heads

    All new intake and exhaust valves

    High performance valve springs

    New rockers

    Mahle Motorsports 3.4 kit running 7.7:1 compression

    All new ARP cylinder head studs

    Web Cam with 158i profile

    Not running any o2 sensors

    RarlyL8 intercooler

    Estimated horsepower is 350-400

    Any more mods would require a standalone ecu

    This car was built to run off the CIS and avoid any stand alone set up

    What is the estimated HP?

  • Reline7500 1 day, 10 hoursago

    What a great looking car and good job on the build!👍
    I was curious if the car has been converted to EFI with Motec or similar engine management?
    Also is there any HP/torque dyno data available after the upgrades were done.

    The first thing that popped into my head was Styx “Renegade”
