This 1975 Porsche 911 was acquired as a project car from Johnston Enterprises and transformed into a purpose-built PCA Club Stock E class race car during the late 1990s. It features a Slant Nose style body kit with steel fenders as well as a 3.0-liter 911SC engine which was rebuilt, blueprinted, and precisely balanced along with the installation of 46mm Weber carburetors, headers, and a custom exhaust. The car is also outfitted with a full roll cage, 935-style coilovers, polyurethane suspension bushings, 930 Turbo brakes, HRE wheels, a Quaife limited-slip differential, and a 5-speed manual gearbox rebuilt with a short ring & pinion. Qualified for Vintage PCA Racing, F Stock, and the Carrera Cup series, this custom street-legal 911 is now being offered for auction by its seller out of Delaware.
This 911 was fitted with a Slant Nose style body kit during the late 1990s including wide steel fenders flares, pop-up headlamps, and boxed rocker panels. A carbon fiber 964 RSR-style spoiler is equipped, and the seller states a new fiberglass front bumper was recently installed. Other details include custom front cooling ducts, aftermarket halogen headlights, Porsche 993 side mirrors, and custom three-piece 17” HRE Fuchs-style wheels measuring 9” wide in front and 10” wide in the rear. These wheels were rebuilt and refinished about two years ago and are currently dressed in Falken Azenis tires (2019). An additional set of HRE wheels is included measuring 16”x9” and 16”x10” with Kumho Victoracer tires. The car is said to have been refinished in its current black color within the last 18 months and some imperfections and signs of overspray are present. A crack and pitting is also noted in the windshield. Detailed images are provided in the gallery.
The cabin has been outfitted for racing with the installation of a full roll cage, a Kirkey driver’s seat, an OMP passenger seats, Williams 6-point harnesses (expired), a MOMO steering wheel & shift knob, a window net, and lightweight door panels with pull straps. The seller notes the rear interior, radio, and air-conditioning system have been removed. The clock and sunroof are inoperable, and the windshield wipers only operate at one speed. All other gauges and accessories are said to be fully functional.
Power comes from a 3.0-liter Porsche 911SC engine that was rebuilt, blueprinted, and balanced at a precise level by engineers at a local university. It features Weber 46mm carburetors, headers, and a custom sport exhaust system. The seller indicates the engine’s compression ratio is 8.5:1 and a recent test showed 130-135psi compression across all cylinders with 1-2% leak down. The rear wheels are driven by a 5-speed 915 manual transaxle which was rebuilt by Gary Fairbanks with a short ring & pinion (8.41) and paired with a Quaife limited-slip differential. Upgraded 930 Turbo brakes have been installed along with stainless steel lines and the suspension included 935-style coilovers, polyurethane bushings, and Charlie Bar sway bars. The seller notes the car weighs approximately 2,350 lbs. without a driver and the fluids were changed within the last 500 miles.
This sale will include a clean Montana title and some documentation.
The seller would like you to know: “I have owned this car since 1996. This 911 was built to maximize the rules for PCA Class E (now F). It had a wonderful racing career with many wins and podiums. It has a Worker Choice award. The car is eligible for the PCA Vintage and Carrera Cup classes. It is great to drive on a weekend for Cars and Coffee and back road carving. Slant Nose and turbo body gets a lot of attention.”

@cybersurge11 The car is in Delaware.

Is the car in Delaware or Montana?
@dasanto2 I want to make sure you know that it is registered. All the street lights, horns, etc. work. You would need to be conscious of your local emissions requirements. With local vintage registration, it's fine where I'm at.
@vsreedharala Unfortunately, no. I didn't have a camera mounted back when I ran PCA. Everything was still VHS back then! ;-)
Any driving/track videos of the car ? beautiful car for the track.
Bid in the amount of $20,000
@BruceDuff - Thank you. I appreciate your prompt and transparent response.
@dasanto2 The car is not what I would call a daily driver. Ii has no heat, air conditioning, or radio and you would still need to come in over the rollbar (which could easily be removed). I have used it on weekends to take nice drives and enjoy the backroads around my area. I did have a friend who was interested in converting it back to a street driver. It would not be expensive but, I think it has great value for a dual-purpose track/race/road car.
@BruceDruff - I have no interest in racing (possibly a a track day or two); in its current condition, how well would this car be suited as a daily driver or weekend car? Any concerns you would note with it passing requirement for road legality?
@Jas0nn Hi Jason and all. I have exchanged emails with Walt Fricke, who oversees the 911Cup rules. Based on our exchange the car will be eligible for 911Cup but, may require a weight penalty if it has an unfair performance advantage. The amount is TBD. See comment; "Because these modifications are already there, we'll find a weight for the car (as long as there are no coil springs installed)." I do want to repeat that the car does not now or ever has had coil springs. It does have threaded shock towers from a 935-style suspension without helper springs. It is on torsion bars. If anyone is interested, I will post Walt's full email. Thank you, Bruce
@cybersurge11 The car is currently registered (I took the plates off for photos). I haven't raced the since the mid-2000's. I moved to other race series. I did do a driver's Ed probably 8-10 years ago. It has been a very rarely used Sunday drive car. It only has the 6 point harnesses.
Love the slant-nose look. When was the last time this puppy was registered on the street and the last time on the track? Has it been sitting up long? Are the original seat belts there or have they been taken out completely for the 6-point harnesses?
Correct - that’s our mid year rules change closing the loophole for Prepared cars. And as it says, only EXISTING Prepared cars are eligible for 911CUP on a case-by-case basis. I’m not trying to take anything away from this car; I just want potential racers to understand this car is not currently eligible for 911CUP as it sits. But if you swap the fenders and make sure the rest of the car complies with our rule set, come race in an awesome - and growing - class!
There are headers and no heat exchangers. Some of the vents and fans still exist. They have never been used since this car was built. Thak you, Bruce
Does the heat work or are there aftermarket headers without heat exchangers on the car?
Hi Nick, thanks for your feedback. I received this on July 16th which was requested;
Effective immediately.
Eligible Models
Rule Change: The 911 models eligible for 911CUP, other than those built to SP911 specifications, are 1978-1983 US and ROW standard SCs, and 1984-1989 US Carrera 3.2s, along with the 1973 Carrera RS and 1990-1994 964 C2s and RSAs. Other existing track prepared 911 models listed in classes D through F Stock, including cars moved up to one of those classes due to Prepared modifications other than those allowed in 911CUP, may be considered on a case-by-case basis by the Rules Committee, with weight adjustment appropriate to the modifications.
Rationale: This change is necessary because when this class was first formulated as a balance of performance class, no attention was paid to the effect of unusual models (especially clones) or Prepared modifications on performance in the base D, E, and F classes. The case-by-case exception’s intent is to prevent adding (or creating new clones of) unusual models, or new Prepared cars for 911CUP, but to accommodate existing race cars. Balancing performance is more art than science, and the less it is a factor the better for this class.
Interesting car - and good luck with sale. But it’s misleading to say this car is eligible for 911CUP. - Jason Nikic (I’m the 911CUP Class Advocate)
@sportscarguy3 Hi, a few clarifications. The suspension does not have the perches and springs for the coilover. The 911 is eligible for the 911Cup Series; not the Carrera Cup. Thank you.
The red centers on the wheels were just powder coat a few years ago. I’m sure the wheels could be disassembled painted and put back together again.
Hi, I am the seller. This car was bought it as a stripped out roller. The full interior is not original to the car. No idea if there is any wiring for the stereo and do not have original seats. Happy to answer any additional questions, thank you, Bruce.
Bid in the amount of $15,000
@curiousoffice got it !
@sportscarguy3 I am not the seller. Just pointing out that 1975 vehicles (including model years 1975 and before) are not required for smog certification in CA.
@curiousoffice thank you for the prompt reply to this California smog emissions question
You are correct it’s a 1975 and that is the cut off year I’m just not sure if it’s pre-1975 or includes 1975 vehicles
Are you?
I can call DMV on Monday
How about the radio, music, any existing wiring or speakers that could be used?
Also, not a huge fan of red, the center of the Fuchs wheels are red. Do you believe there’s an easy way to correct that? Powder coating, perhaps?
Do you have the factory seats?
@sportscarguy3 It's a 1975 car. California smog omissions are not applicable.
Probably no cats on the exhaust, I haven’t looked at the pictures yet, but probably would not pass California smog omissions, as is?
Was there ever a radio or any source of music, speakers, wiring, etc.?
