Initially delivered as a Targa, this 1982 Porsche 911SC is said to have been converted into a slant-nose cabriolet under the original ownership in 1989. The car remained in California for much of its life before a two-year refurbishment began in 2017, which included a refinish in Slate Grey along with various upgrades and modifications. It is powered by a 3.3-liter flat-six engine sourced from a 911 Turbo and overhauled by South Shore Performance, paired with a 4-speed manual transmission refreshed by Patrick Motorsports. Performance enhancements include a K27 turbocharger, Fabspeed intercooler, Billy Boat exhaust system, and a limited-slip differential. Additional features include a front-mounted oil cooler, a RUF front valance, steel fender flares, a tea tray rear spoiler, Elephant Racing suspension components, 17” Fuchs-style wheels, Griffiths air conditioning, and a custom sound system. This 911 was awarded Best Air-Cooled Turbo at the 2019 Great Marques Concours in Old Westbury, New York, and has been driven approximately 5k miles since the refurbishment. It is now being offered for auction by the selling dealer out of Ohio.
This 911SC was originally configured as a Targa and finished in Guards Red before being converted to a slant-nose Turbo-style cabriolet in 1989. The conversion included steel fenders, boxed rocker panels, and a tea tray rear spoiler. A RUF front valance has also been fitted. Following a previous owner’s acquisition in 2017, the body was disassembled, stripped, and refinished in Slate Grey. This refurbishment also included a new windshield, new rubber window and door seals, and tinted side windows. The previously installed RS-style oil cooler was replaced with a new unit, and a new black canvas manual convertible top with a matching boot was fitted. The car rides on 17” Lindsey Racing wheels featuring Fuchs centers and BBS deep-dish barrels, mounted with BFGoodrich G-Force Comp 2 A/S tires sized 235/45 in front and 275/40 in the rear, dated from 2019. Detailed images are provided in the gallery along with an accident-free CARFAX report.
The black-upholstered cabin was refreshed using components sourced from a lower-mileage donor 911 and features seats from a 996 model. Replacement front seatbelts were installed, and custom three-point belts were added for the rear seats. A MOMO steering wheel and aluminum gauge bezels were also fitted. Electrical components were updated, including the window switches, side mirror controls, power door locks, and windshield wiper assembly. An upgraded Griffiths air conditioning system has been installed, and removable cupholders are positioned atop the door pockets. The front trunk compartment was repainted and lined with new material. Sound system upgrades include a Pioneer Bluetooth/CD/USB head unit, JL Audio and Alpine speakers, and an 8” Kicker subwoofer with an adjustable gain knob mounted in the center console. Additional equipment includes a Viper alarm system with remote-start capability. The cruise control and automatic heat control systems were retained from the donor car but are currently nonfunctional. Black Lloyd floor mats with red embroidered Porsche script were added over the carpeting. The 180-mph speedometer was rebuilt by Hollywood Speedometer and fitted during the refurbishment, at which point the odometer was reset to zero. A 2-bar boost gauge was installed in place of the factory clock, and a digital air-fuel O2 gauge was mounted in the center console.
The 911 Turbo-sourced 3.3-liter flat-six engine was overhauled in 2019 by South Shore Performance of Freeport, New York. It features a rebuilt K27 hybrid turbocharger, a Fabspeed intercooler and intake system, 964-grind camshafts, a competition valve job, an MSD ignition coil, a rebuilt wastegate with a 1-bar spring, an adjustable warm-up regulator, and a vacuum-activated 993 pop-off valve. The Bosch CDI ignition system was also rebuilt. Power is sent to the rear wheels through a Type 930 4-speed manual transmission, which was refurbished and converted to a short bell housing configuration by Patrick Motorsports. Taller first, second, and fourth gears were installed, along with a factory limited-slip differential. A SACHS sport clutch was paired with a high-performance Stage 1 pressure plate featuring a forged aluminum cover and iron friction plate. Billy Boat exhaust headers and heat exchangers were also added. Suspension upgrades from Elephant Racing include Bilstein shocks and struts, 21mm front and 28mm rear torsion bars, a quick-change strut brace, and Turbo tie rods. Additional improvements include a steering rack spacer kit to reduce bump steer, along with new bushings, camber plates, and ball joints. A full engine reseal was completed in 2021.
This sale will include a clean title. The CARFAX report shows that a branded title was previously issued due to a mileage discrepancy.

@TheCleaner No, there are no build photos available. Without taking it apart, we can't tell what was done.
Starting out as a 911SC Targe does documentation or photos exist addressing the structural components required for cabriolet conversion?
@82turboruf 5,392 miles are on the motor since the restoration. I'm sorry, we don't know about the wastegate.
@r32fan Sorry, we don't. We just uploaded a cold start and walk around video.

Just got back from looking at this car - I thank the sellers for accommodating my request. No test drive; no engine start. Nonetheless I really like this build; it catches your eye (and your breath). The fit/finish is very solid; doors close well; lines seem straight; cabin is great. Top fits like a targa. Seats are a combo of manual and electric; driver’s seat motor worked for up/down while it runs on rails for back and forth. Didn’t get under the car but have no reason to believe the suspension, engine, and exhaust are different from described. Drivable from day 1. Not sure I’ll be the winner but sure do like it.
PS @SV I missed in the original description it has a front oil cooler so def should not run hot
I like this build. Confused about the total miles on it and how many after on
the 3.3 turbo motor. 1 Bar wastegate spring?

@Painlss85 Upon further review and a call to our DMV, we determined that the owner incorrectly chose exceeding mechanical limits when transferring the car to an Ohio title, which brands the title in Ohio. He should have chosen not actual miles because the odometer was set to 0 when the car was restored. We are having this corrected.
@SZ You're welcome. Everything you mentioned is in very good condition with no issues, as the car only has 5,392 miles on it since being completely restored. The top opens and closes smoothly and the seals are still soft and supple. It doesn't leak when being washed, and we've never driven it in the rain. It's also never overheated on us, and the engine compartment seals and paint has no issues.
@Painlss85 It is only due to mileage. The “ Exceeds mechanical limits” is common on cars when the odometer rolls over and is reported as such to Carfax.
Thanks for getting back to me. I don't need a video, but it would be helpful if you could confirm the condition of the convertible top. Does it open and close smoothly and do you know if it's watertight (any water ingress during washing or weather)? I've had 2 80's 911 turbos and noticed both can run hot, especially if there is a non-stock exhaust setup. Have there been any problems with overheating temps or any damage in the engine compartment area to paint, seals etc.? Many thanks for your feedback.
@SZ It is indeed manual. Would you still like a video?
@Collexxxter It is indeed manual. Would you still like a video?
Many thanks Collexxxter.
@SZ - tops were not all electric until - I believe - 1986. My 1985 M491 cab manual. Better, fewer issues. Technically, as a 1982, no cabs at all this year. 1983 first.
Can you please provide a video of the top opening and closing? All convertible 911s have electric roofs but this is apparently manual. It would be helpful to understand the conversion from targa to convertible and how it operates. Many thanks.
I am very interested to know why the title has been "branded". the mileage discrepancy aside, there must be another reason why the title has been issued in this manner. Far from the extensive work that has been done to the car and the refurbishment, which appears first rate the title issue has me concerned. As a dealer one would think that you are knowledgeable and should include all the information associated with that concern initially in the listing. Please explain as to all the facts that have contributed to the branded title. I love the appearance of a slant nose, always have. childhood want. I will bid if the reasons seem to be nominal rather than serious. I am looking forward to your explanation.

@Shredguy Under our ownership of the car, we ran it on a dyno and we have a sheet that says 276 hp. However, we were not pushing it to the max because we were just checking it for reliability. There is, however, a video on a prior add on another platform shows the car topping 425 HP. While we did not confirm that HP on they dyno ourselves, we have not changed anything with the engine since the time it was listed on the other auction.

Any idea on HP?
